(b) Category B1, divided into the following subcategories: - B1.1 Aeroplanes Turbine; - B1.2 Aeroplanes Piston; - B1.3 Helicopters Turbine; - B1.4 Helicopters Piston. (c) Category B2 The B2 licence is applicable to all aircraft. (d) Category B2L The B2L licence is applicable to all aircraft other than those in Group 1 as set out in point 66.A.5(1) and is divided into the following ‘system ratings’: - communication/navigation (com/nav), - instruments, - autoflight, - surveillance, - airframe systems. A B2L licence shall contain, as a minimum, one system rating. (e) Category B3 The B3 licence is applicable to piston-engine non-pressurised aeroplanes of 2000kg Maximum Take-off Mass (MTOM) and below. (f) Category L, divided into the following subcategories: - L1C: composite sailplanes, - L1: sailplanes, - L2C: composite powered sailplanes and composite ELA1 aeroplanes, - L2: powered sailplanes and ELA1 aeroplanes, - L3H: hot-air balloons, - L3G: gas balloons, - L4H: hot-air airships, - L4G: ELA2 gas airships, Issue: 4.00 3 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements - L5: gas airships other than ELA2. (g) Category C The C licence is applicable to aeroplanes and helicopters. GM 66.A.3 Licence categories ‘ELA1 aeroplanes’ refers to those aeroplanes which meet the definition of ‘ELA1 aircraft’ ‘ELA2 gas airships’ refers to those gas airships which meet the definition of ‘ELA2 aircraft’. ‘Gas airships other than ELA2’ refers to those gas airships which do not meet at least one condition of the definition of ‘ELA2 aircraft’. NOTE: The ‘ELA2 aircraft’ category includes all ‘ELA1 aircraft’. The term ‘powered sailplane’ includes: - those powered sailplanes which may take off solely by means of their own power (self- launching sailplanes); and - self-sustaining powered sailplanes; and - touring motor gliders (TMGs). While the L1C subcategory only includes composite sailplanes, the L1 subcategory includes all sailplanes (composite, metal and wood). While the L2C subcategory only includes composite powered sailplanes and composite ELA1 aeroplanes, the L2 subcategory includes all powered sailplanes and ELA1 aeroplanes (composite, metal and wood). In the case of maintenance of mixed balloons (combination of gas and hot air), it is required to hold both L3G and L3H subcategories. For the B2L licence, a ‘system rating’ is a rating which gives privileges to release maintenance on the aircraft systems covered by the ‘system rating’ and electrical systems. The sentence ‘shall contain, as a minimum, one system rating’ refers to the fact that the application for a B2L licence should be made for any of the system ratings or any combination of the system ratings specified in 66.A.3. There is no specific order in which the system ratings should be applied for. Any combination of system ratings is possible. Issue: 4.00 4 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements The description of systems covered by the different system ratings is provided in Appendix I ‘Basic Knowledge Requirements’ under paragraph ‘2. Modularisation’, subparagraph related to ‘Categories B2 and B2L’. Issue: 4.00 5 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements MCAR-66.A.5 Aircraft groups For the purpose of ratings on aircraft maintenance licences, aircraft shall be classified into the following groups: (1) Group 1: complex motor-powered aircraft; multi-engine helicopters; other than piston- engine aeroplanes, with maximum certified operating altitude exceeding FL290; aircraft equipped with fly-by-wire systems; gas airships other than ELA2. The CAA may decide to classify into Group 2, Group 3 or Group 4, as appropriate, an aircraft which meets the conditions set out in the first subparagraph, if it considers that the lower complexity of the particular aircraft justifies so. (2) Group 2: aircraft other than those in Group 1 belonging to the following subgroups: (i) subgroup 2a: - single turboprop engine aeroplanes, - those turbine-engine aeroplanes classified by the CAA in this subgroup because of their lower complexity. (ii) subgroup 2b: - single turbine engine helicopters, - those multiple turbine engine helicopters classified by the CAA in this subgroup because of their lower complexity. (iii) subgroup 2c: - single piston engine helicopters, - those multiple piston engine helicopters classified by the CAA in this subgroup because of their lower complexity.

(b) (Reserved) (c) In addition to the documents required in points 66.A.10(a) and 66.B.105, as appropriate, the applicant for additional basic categories or subcategories to an aircraft maintenance licence shall submit his/her current original aircraft maintenance licence to the CAA together with CAA Form 19 (d) (Reserved) (e) (Reserved) (f) Each application shall be supported by documentation to demonstrate compliance with the applicable theoretical knowledge, practical training and experience requirements at the time of application. Issue: 4.00 8 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements AMC 66.A.10 Application 1. Maintenance experience should be written up in a manner that the reader has a reasonable understanding of where, when and what maintenance constitutes the experience. A task by task account is not necessary but at the same time a bland statement “X years maintenance experience completed” is not acceptable. A log book of maintenance experience is desirable and the CAA may require such log books to be kept. It is acceptable to cross refer in CAA Form 19 to other documents containing information on maintenance. 2. Applicants claiming the maximum reduction in 66.A.30(a) total experience based upon having successfully completed 147.A.200 approved basic training, should include the MCAR- 147 certificate of recognition for approved basic training. 3. Applicants claiming reduction in MCAR-66.A.30(a) total experience based upon having successfully completed technical training in an organisation or institute recognised by the CAA as a competent organisation or institute, should include the relevant certificate of successful completion of training. GM 66.A.10(a) Application When an application is made for a licence in the B2L category, the applicant should specify on the CAA Form 19: − the system rating or the combination of system ratings the applicant applies for; and − the aircraft rating, considering that according to 66.A.45(e), a B2L licence endorsed with full subgroup 2b can be endorsed also with full subgroup 2c. When applying for the addition of a system rating on a B2L licence, the applicant should provide together with the application, the demonstration of compliance with the experience requirements related to the system the applicant applies for. When a B2L licence holder applies for the extension of a B2L licence to add a new system rating, he/she needs to demonstrate the practical experience required by 66.A.30(a)(2a) for the system rating but also the practical experience required by 66.A.45(e) and (f) in case the aircraft group is different. When a B2L licence holder applies for the change of his/her B2L licence to the B2 category, he/she needs only to: − demonstrate by examination the differences between the basic knowledge corresponding to the B2L licence held and the basic knowledge of the B2 licence, as described in Appendix I; and − demonstrate the additional experience described in Appendix IV. These requirements can be found also in 66.B.110. When an applicant applies for the extension of his/her B2L licence to a B2 licence and he/she meets the relevant requirements, the B2L licence is replaced by the B2 licence. Issue: 4.00 9 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements MCAR-66.A.15 Eligibility An applicant for an aircraft maintenance licence shall be at least 18 years of age.

Issue: 4.00 12 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements GM 66.A.20(a) Privileges 1. The following definitions apply: Electrical system means the aircraft electrical power supply source, plus the distribution system to the different components contained in the aircraft and relevant connectors. Lighting systems are also included in this definition. When working on cables and connectors which are part of these electrical systems, the following typical practices are included in the privileges: - Continuity, insulation and bonding techniques and testing; - Crimping and testing of crimped joints; - Connector pin removal and insertion; - Wiring protection techniques. Avionics system means an aircraft system that transfers, processes, displays or stores analogue or digital data using data lines, data buses, coaxial cables, wireless or other data transmission medium, and includes the system’s components and connectors. Examples of avionics systems include the following: - Autoflight; - Communication, Radar and Navigation; - Instruments (see NOTE below); - In Flight Entertainment Systems; - Integrated Modular Avionics (IMA); - On-Board Maintenance Systems; - Information Systems; - Fly by Wire Systems (related to ATA27 “Flight Controls”); - Fibre Optic Control Systems. NOTE: Instruments are formally included within the privileges of the B2 and B2L with system rating ‘instruments’. However, maintenance on electromechanical and pitot-static components may also be released by a B1, B3 or L license holder. Simple test means a test described in approved maintenance data and meeting all the following criteria: - The serviceability of the system can be verified using aircraft controls, switches, Built-in Test Equipment (BITE), Central Maintenance Computer (CMC) or external test equipment not involving special training. - The outcome of the test is a unique go – no go indication or parameter, which can be a single value or a value within an interval tolerance. No interpretation of the test result or interdependence of different values is allowed. - The test does not involve more than 10 actions as described in the approved maintenance data (not including those required to configure the aircraft prior to the test, i.e. jacking, flaps down, etc, or to return the aircraft to its initial configuration). Pushing Issue: 4.00 13 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements a control, switch or button, and reading the corresponding outcome may be considered as a single step even if the maintenance data shows them separated. Troubleshooting means the procedures and actions necessary, using approved maintenance data, in order to identify the root cause of a defect or malfunction. It may include the use of BITE or external test equipment. Line maintenance: refer to AMC1 145.A.10 Base maintenance: refer to AMC1 145.A.10 2. The category B3 licence does not include any A subcategory. Nevertheless, this does not prevent the B3 licence holder from releasing maintenance tasks typical of the A1.2 subcategory for piston-engine non-pressurized aeroplanes of 2000 Kg MTOM and below, within the limitations contained in the B3 licence. 3. The B1.2 and B3 licences do not include any L subcategory. Nevertheless, the holder of a B1.2 or B3 licence with the appropriate ratings is entitled to receive, upon application, licences in the L1 and L2 subcategories under the conditions described in point 66.B.110(d). 4. The privileges of the B2 licence with given aircraft ratings include the privileges of the B2L licence for all the system ratings for the same aircraft ratings. Nevertheless, the holder of a B2 licence with given aircraft ratings may apply for a B2L licence in order to include a different aircraft rating if the applicant only wants to demonstrate compliance with the experience requirements for certain system ratings. 5. The category C licence permits certification of base maintenance by the issue of a single certificate of release to service for the complete aircraft after the completion of all such maintenance. The basis for this certification is that the maintenance has been carried out by competent mechanics and category B1, B2, B2L, B3 and L support staff, as appropriate, have signed for the maintenance tasks under their respective specialisation. The principal function of category C certifying staff is to ensure that all required maintenance has been called up and signed off by category B1, B2, B2L, B3 and L support staff, as appropriate, before issue of the certificate of release to service. Only category C personnel who also hold category B1, B2, B2L, B3 and L qualifications may perform both roles in base maintenance. AMC 66.A.20(a)(4) Privileges ‘Within the limits of the system ratings specifically endorsed on the licence’ refers to the fact that the privileges of the licence holder are limited: − to the group/subgroup of aircraft endorsed on the licence, but also − to the system rating(s) endorsed. When an applicant wishes to get the privilege to issue certificates of release to service and to act as support staff for electrical and avionics tasks within powerplant and mechanical systems, Issue: 4.00 14 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements he/she should apply for the rating ‘airframe system’ on the B2L licence. The reason is that the ‘airframe systems’ rating is the only rating which covers completely the electrical and avionics tasks of the powerplant and mechanical systems of the aircraft. Issue: 4.00 15 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements AMC 66.A.20(b)2 Privileges The 6 months maintenance experience in 2 years should be understood as consisting of two elements, duration and nature of the experience. The minimum to meet the requirements for these elements may vary depending on the size and complexity of the aircraft and type of operation and maintenance. 1. Duration: Within an approved maintenance organization: - 6 months working with the same organisation; or - 6 months split up into different blocks, working within the same or in different organisations. The 6 months period can be replaced by 100 days of maintenance experience in accordance with the privileges, whether they have been performed within an approved organisation, or as independent certifying staff according to MCAR-M.A.801(b)1 or as a combination thereof. When certifying staff maintains and releases aircraft in accordance with MCAR-M.A.801(b)1, in certain circumstances this number of days may even be reduced by 50% when agreed in advance by the CAA. These circumstances consider the cases where the holder of a MCAR- 66 licence happens to be the owner of an aircraft and carries out maintenance on his own aircraft, or where a licence holder maintains an aircraft operated for low utilization, that does not allow the licence holder to accumulate the required experience. This reduction should not be combined with the 20% reduction permitted when carrying out technical support, or maintenance planning, continuing airworthiness management or engineering activities. To avoid a too long period without experience, the working days should be spread over the intended 6 months period. 2. Nature of the experience: Depending on the category of the aircraft maintenance licence, the following activities are considered relevant for maintenance experience: - Servicing; - Inspection; - Operational and functional testing; - Troubleshooting; - Repairing; - Modifying; - Changing component; - Supervising these activities; - Releasing aircraft to service. For category A licence holders, the experience should include exercising the privileges, by means of performing tasks related to the authorization on at least one aircraft type for each Issue: 4.00 16 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements licence subcategory. This means tasks as mentioned in AMC 145.A.30(g), including servicing, component changes and simple defect rectifications. For category B1, B2, B2L, B3 and L for every aircraft included in the authorization the experience should be on that particular aircraft or on a similar aircraft within the same licence (sub)category. Two aircraft can be considered as similar when they have similar technology, construction and comparable systems, which means equally equipped with the following (as applicable to the licence category): - Propulsion systems (piston or turboprop or turbofan or turboshaft or jet-engine or push propellers); and - Flight control systems (only mechanical controls or hydromechanically powered controls or electromechanically powered controls); and - Avionic systems (analogue systems or digital systems); and - Structure (manufactured of metal or composite or wood). For licences endorsed with (sub)group ratings: - In the case of B1 licence endorsed with group (sub)group ratings (either manufacturer sub-group or full (sub)group) as defined in MCAR-66.A.45 the holder should show experience on at least one aircraft type per (sub)group and per aircraft structure (metal, composite, wood). - In the case of a B2 or B2L licence endorsed with (sub)group ratings (either manufacturer subgroup or full (sub)group) as defined in MCAR-66.A.45 the holder should show experience on at least one aircraft type per (sub)group. - In the case of a B3 licence endorsed with the rating “piston-engine non-pressurized aeroplanes of 2000 Kg MTOM and below” as defined in 66.A.45, the holder should show experience on at least one aircraft type per aircraft structure (metal, metal-tubing with fabric, composite or wooden). For category C, the experience should cover at least one of the aircraft types endorsed on the licence. For a combination of categories, the experience should include some activities of the nature shown in paragraph 2 in each category. A maximum of 20% of the experience duration required may be replaced by the following relevant activities on an aircraft type of similar technology, construction and with comparable systems: - Aircraft maintenance related training as an instructor/assessor or as a student; - Maintenance technical support/engineering; - Maintenance management/planning. The experience should be documented in an individual log book or in any other recording system (which may be an automated one) containing the following data: Issue: 4.00 17 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements - Date; - Aircraft type; - Aircraft identification i.e. registration; - ATA chapter (optional); - Operation performed i.e. 100 FH check, MLG wheel change, engine oil check and complement, SB embodiment, troubleshooting, structural repair, STC embodiment, etc; - In the particular case of MCAR-145 organisations, the type of maintenance i.e. base, line; - Type of activity i.e. perform, supervise, release; - Subcategory used (A1, A2, A3, A4, B1.1, B1.2, B1.3, B1.4, B2, B2L, B3, C or L1, L1C, L2, L2C, L3G, L3H, L4G, L4H, L5); - Duration in days or partial-days Issue: 4.00 18 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements GM 66.A.20(b)2 Privileges The sentence “met the provision for the issue of the appropriate privileges” included in 66.A.20(b)2 means that during the previous 2 years the person has met all the requirements for the endorsement of the corresponding aircraft rating (for example, in the case of aircraft in Group 1, theoretical plus practical element plus, if applicable, on-the-job training). This supersedes the need for 6 months of experience for the first 2 years. However, the requirement of 6 months of experience in the preceding 2 years will need to be met after the second year. Issue: 4.00 19 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements AMC 66.A.20(b)3 Privileges The wording “has the adequate competence to certify maintenance on the corresponding aircraft” means that the licence holder and, if applicable, the organisation where he/she is contracted/employed, should ensure that he/she has acquired the appropriate knowledge, skills, attitude and experience to release the aircraft being maintained. This is essential because some systems and technology present in the particular aircraft being maintained may not have been covered by the training/examination/experience required to obtain the licence and ratings. This is typically the case, among others, in the following situations: - Type ratings which have been endorsed on a licence in accordance with Appendix I to AMC to MCAR-66 “List of Type Ratings” after attending type training/on-the-job training which did not cover all the models/variants included in such rating. For example, a licence endorsed with the rating Airbus A318/A319/A320/A321 (CFM56) after attending type training/on-the- job training covering only the Airbus 320 (CFM56). - Type ratings which have been endorsed on a licence in accordance with Appendix I to AMC to MCAR-66 “List of Type Ratings” after a new variant has been added to the rating in Appendix I, without performing difference training. For example, a licence endorsed with the rating Boeing 737-600/700/800/900 for a person who already had the rating Boeing 737- 600/700/800, without performing any difference training for the 737-900. - Work being carried out on a model/variant for which the technical design and maintenance techniques have significantly evolved from the original model used in the type training/on- the-job training. - Specific technology and options selected by each customer which may not have been covered by the type training/on-the-job training. - Changes in the basic knowledge requirements of Appendix I to MCAR-66 not requiring re- examination of existing licence holders (grandfathered privileges). - The endorsement of group/subgroup ratings based on experience on a representative number of tasks/aircraft or based on type training/examination on a representative number of aircraft. - Persons meeting the requirements of 6 months of experience every 2 years only on certain similar aircraft types as allowed by AMC 66.A.20(b)2. - Persons holding a MCAR-66 licence with limitations, obtained through conversion of national qualifications (66.A.70), where such limitations are going to be lifted after performing the corresponding basic knowledge examinations. In this case, the type ratings endorsed in the licence may have been obtained in the national system without covering all the aircraft systems (because of the previous limitations) and there will be a need to assess and, if applicable, to train this person on the missing systems. Additional information is provided in AMC 145.A.35(a).

Issue: 4.00 27 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements AMC1 66.A.30(a) Basic experience requirements 1. Maintenance experience on operating aircraft: - Means the experience of being involved in maintenance tasks on aircraft which are being operated by airlines, air taxi organisations, aero clubs, owners, etc; as relevant to the licence category/subcategory; - Should cover a wide range of tasks in length, complexity and variety; - Aims at gaining sufficient experience in the real environment of maintenance as opposed to only the training school environment; - May be gained within different types of maintenance organisations (MCAR-145, M.A. Subpart F, MCAR-CAO, FAR-145, etc) or under the supervision of independent certifying staff; - May be combined with MCAR-147 approved training (or other training approved by the CAA) so that periods of training can be intermixed with periods of experience, similar to an apprenticeship; - may be full-time or part-time, either as professional or on a voluntary basis; - in the case of the L licence, it is acceptable that the 1 or 2 years of experience required by 66.A.30(a)(2b) covers maintenance performed only during the weekends (or equivalent periods) as long as the applicant has achieved a sufficient level of competency related to the applicable licence subcategory as attested by the corresponding statement(s) issued by the maintenance organisation(s) or independent certifying staff that supervised the applicant. 2. A skilled worker is a person who has successfully completed a training, acceptable to the CAA, involving the manufacture, repair, overhaul or inspection of mechanical, electrical or electronic equipment. The training would include the use of tools and measuring devices. 3. In the case of an applicant for a licence including several categories/subcategories, it is acceptable to combine the periods of experience as long as there is a sufficient experience for each category/subcategory during the required period. Examples: - Application for a B1.1 (turbine aeroplanes) + B1.3 (turbine helicopters): The Regulation requires 5 years of experience for B1.1 and 5 years of experience for B1.3 for an applicant with no relevant previous technical training: - It is not acceptable to combine the experience in a single 5-year period where the applicant has been working for 3 years on turbine aeroplanes and 2 years on turbine helicopters. Issue: 4.00 28 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements - However, it is acceptable to combine the experience in a single 5-year period if the applicant has been working for 5 years on turbine aeroplanes and turbine helicopters (for example, aeroplanes in the morning, helicopters in the afternoon, or a few days every week on aeroplanes and a few days every week on helicopters). - Application for a B1.1 (turbine aeroplanes) + B2 (avionics): The Regulation requires 5 years of experience for B1.1 and 5 years of experience for B2 for an applicant with no relevant previous technical training. - It is not acceptable to combine the experience in a single 5-year period where the applicant has been working for 3 years on turbine aeroplanes (with no avionics work) and 2 years on avionics systems. - However, it is acceptable to combine the experience in a single 5-year period if the applicant has been working for 5 years on structures, powerplant, mechanical and electrical systems and avionics (for B1.1 tasks in the morning, B2 tasks in the afternoon, or a few days every week for B1.1 tasks and a few days every week for B2 tasks). - Application for a B1.1, B1.2, B1.3, B1.4 and B2: The Regulation requires 5 years of experience for B1.1, B1.3 and B2 and 3 years of experience for B1.2 and B1.4 for an applicant with no relevant previous technical training. - In this case, it is very unlikely that the experience for each category/subcategory would be sufficient. 4. For a category C applicant that holds an academic degree, the participation in the performance of maintenance tasks on operating aircraft may include maintenance, maintenance planning, quality assurance, record-keeping, spare parts management and engineering development. - ‘Experience in working in a civil aircraft maintenance environment on a representative selection of tasks directly associated with aircraft maintenance’ means experience gained at an organisation that is approved in accordance with MCAR-145, MCAR-CAO, MCAR-CAMO or similar, or experience in performing comparable work that is directly related to the continuing airworthiness of aircraft within a competent authority. Similar work performed on state aircraft may be acceptable as well. - ‘Including 6 months of participation in the performance of base maintenance tasks’ on operating aircraft means experience gained through the active participation in base maintenance checks at maintenance organisations. - If the applicant has acquired experience on operating CMPA, the corresponding category C licence should be issued. If the experience acquired has been limited to other Issue: 4.00 29 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements than CMPA, then only the corresponding category C licence with respect to other than CMPA should be issued. - While it is strongly recommended that the participation in the performance of maintenance on aircraft should be at the level required for the issue of a B1 or B2 licence, the objective of the required experience is to gain insight into the performance of base maintenance. The applicant for an academic category C licence should be aware of the type of maintenance carried out before the signature of support staff and understand their roles in the release-to-service process of base maintenance. It is encouraged that the future category C licence holder participates in both simple and complex tasks during their experience in base maintenance and gains insight in some aircraft critical systems. - In the case presented in point 66.A.30(e), for the required experience gained outside the Maldivian civil regulatory framework, at least 1 year should be in a MCAR-145 or MCAR- CAO environment, including participation in the performance of base maintenance tasks for 6 months Issue: 4.00 30 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements GM1 66.A.30(a) Basic experience requirements The table below summarises the basic experience requirements for the category C licence.

When a person already holds a type rating on the licence and such type rating is amended in the Appendix I to AMC to MCAR-66 in order to include additional models/variants, there is no need for additional type training for the purpose of amending the type rating in the licence. The rating should be amended to include the new variants, upon request by the applicant, without additional requirements. However, it is the responsibility of the licence holder and, if applicable, the maintenance organisation where he/she is employed to comply with 66.A.20(b)3, MCAR- 145.A.35(a) and MCAR-M.A.607(a), and MCAR-CAO.A.040 as applicable, before he/she exercises certification privileges. Similarly, type training courses covering certain, but not all the models/variants included in a type rating, are valid for the purpose of endorsing the full type rating. AMC 66.A.45(d);(e)3;(f)1;(g)1;(h) Endorsement with aircraft ratings 1. The ‘practical experience’ should cover a representative cross section including at least: – for categories B1, B2, B2L and B3: 50 % of the tasks contained in Appendix II to the AMC relevant to the licence category and to the applicable aircraft type ratings or aircraft (sub)group ratings being endorsed; − for category L: - in the subcategories L1, L1C, L2 or L2C: 50 % as in the paragraph related to B1, B2, B2L or B3; - in the subcategories L3H and L3G for ‘Balloons’ or L4H, L4G and L5 for ‘Airships’, 80 % of the tasks should be demonstrated, and should include the tasks identified with an asterisk (*) in the Appendix; Issue: 4.00 40 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements This experience should cover tasks from each paragraph of the Appendix II list. Other tasks than those in the Appendix II may be considered as a replacement when they are relevant. In the case of (sub)group ratings, this experience may be shown by covering one or several aircraft types of the applicable (sub)group and may include experience on aircraft classified in group 1, 2 and/or 3 as long as the experience is relevant. The practical experience should be obtained under the supervision of authorised certifying staff. 2. In the case of endorsement of individual type ratings for Group 2 and Group 3 aircraft, for the second aircraft type of each manufacturer (sub)group the practical experience should be reduced to 30% of the tasks contained in Appendix II to AMC relevant to the licence category and to the applicable aircraft type. For subsequent aircraft types of each manufacturer (sub) group this should be reduced to 20%. 3. Practical experience should be demonstrated by the submission of records or a log book showing the Appendix II tasks performed by the applicant. Typical data to be recorded are similar to those described in AMC 66.A.20(b)2. Issue: 4.00 41 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements AMC 66.A.45(e) Endorsement with aircraft ratings 1. For the granting of manufacturer subgroup ratings for Group 2 aircraft, for B1 and C licence holders, the sentence “at least two aircraft types from the same manufacturer which combined are representative of the applicable manufacturer subgroup” means that the selected aircraft types should cover the technologies relevant to the manufacturer subgroup in the following areas: - Flight control systems (mechanical controls / hydromechanically powered controls / electromechanically powered controls); and - Avionic systems (analogue systems / digital systems); and - Structure (manufactured of metal / composite / wood). In cases where there are very different aircraft types within the same manufacturer subgroup, it may be necessary to cover more than two aircraft types to ensure adequate representation. For this purpose it may be possible to use aircraft types from the same manufacturer classified in Group 1 as long as the selected aircraft belong to the same licence subcategory for which the rating will be endorsed. 2. For the granting of full subgroup ratings for Group 2 aircraft, for B1 and C licence holders, the sentence “at least three aircraft types from different manufacturers which combined are representative of the applicable subgroup” means that the selected aircraft types should cover all the technologies relevant to the manufacturer subgroup in the following areas: - Flight control systems (mechanical controls / hydromechanically powered controls / electromechanically powered controls); and - Avionic systems (analogue systems / digital systems); and - Structure (manufactured of metal / composite / wood). In cases where there are very different aircraft types within the same subgroup, it may be necessary to cover more than three aircraft types to ensure adequate representation. For this purpose it may be possible to use aircraft types from different manufacturers classified in Group 1 as long as the selected aircraft belong to the same licence subcategory for which the rating will be endorsed. 3. For manufacturer subgroup ratings, the term “manufacturer” means the TC holder defined in the certification data sheet, which is reflected in the list of type ratings in Appendix I to AMC to MCAR-66. In the case of an aircraft rating where the type rating refers to a TC holder made of a combination of two manufacturers which produce a similar aircraft (i.e. AGUSTA / BELL HELICOPTER TEXTRON or any case of aircraft similarly built by another manufacturer) this combination should be considered as one manufacturer. Issue: 4.00 42 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements As a consequence: - When a licence holder gets a manufacturer type or a manufacturer subgroup rating made of a combination of manufacturers, it covers the combination of such manufacturers. - When a licence holder who intends to endorse a full subgroup rating selects three aircraft from different manufacturers, this means from different combinations of manufacturers as applicable. Issue: 4.00 43 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements GM1 66.A.45(h)(ii) Endorsement with aircraft ratings For subcategories L1 and L2, it is possible to endorse the corresponding ratings with limitations depending on the type of structures covered by the experience gained. For subcategory L3G, it is possible to endorse the rating ‘gas balloons’ with a limitation to ‘other than ELA1 gas balloons’ if the experience gained only covers ELA1 gas balloons. However, the limitations referred to in 66.A.45(h)(ii) do not apply for subcategories L1C, L2C, L3H, L4H and L4G. The ratings on these licences can only be obtained after demonstration of the appropriate experience representative of the full scope of the licence subcategory. Issue: 4.00 44 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements MCAR-66.A.50 Limitations (a) Limitations introduced on an aircraft maintenance licence are exclusions from the certification privileges and, in the case of limitations referred to in point 66.A.45, they affect the aircraft in its entirety. (b) For limitations referred to in point 66.A.45, limitations shall be removed upon: 1. demonstration of appropriate experience, or 2. after a satisfactory practical assessment performed by the CAA. (c) For limitations referred to in point 66.A.70, limitations shall be removed upon satisfactory completion of examination on those modules/subjects defined in the applicable conversion report. Issue: 4.00 45 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements AMC 66.A.50(b) Limitations 1. The appropriate experience required to remove the limitations referred in 66.A.45(f)(g) and (h) should consist of the performance of a variety of tasks appropriate to the limitations under the supervision of authorised certifying staff. This should include the tasks required by a scheduled annual inspection. Alternatively, this experience may also be gained, if agreed by the competent authority, by theoretical and practical training provided by the manufacturer, as long as an assessment is further carried out and recorded by this manufacturer. 2. It is acceptable to have this experience on just one aircraft type, provided this type is representative of the (sub)group in relation to the limitation being removed. 3. (Reserved) 4. The application for the limitation removal should be supported by a record of experience signed by the authorised certifying staff or by an assessment signed by the manufacturer after completion of the applicable theoretical and practical training. Issue: 4.00 46 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements MCAR-66.A.55 Evidence of qualification Personnel exercising certification privileges as well as support staff shall produce their licence, as evidence of qualification, within 24 hours upon request by an authorised person. MCAR-66.A.70 Conversion Provisions (a) The holder of a valid certifying staff qualification issued by the CAA, prior to the date of entry into force of MCAR-66 shall be issued an aircraft maintenance licence without further examinations subject to conditions specified in Section B Subpart D. (b) A person undergoing a certifying staff qualification process approved by the CAA, prior to the date of entry into force of MCAR-66 may continue to be qualified. The holder of a certifying staff qualification gained following such qualification process shall be issued an aircraft maintenance licence without further examination subject to the conditions specified in the applicable conversion report. (c) Where necessary, the aircraft maintenance licence shall contain limitations in accordance with point 66.A.50 to reflect the differences between: i. the scope of the certifying staff qualification valid in the Maldives before the entry into force of MCAR-66 and ii. the basic knowledge requirements and the basic examination standards laid down in Appendix I and II to MCAR-66. (d) By derogation from point (c), for aircraft not used by licenced air carriers in accordance with MCAR-Air Operations, other than complex motor-powered aircraft, and for balloons, sailplanes, motor-powered sailplanes and airships, the aircraft maintenance licence shall contain limitations in accordance with MCAR-66.A.50 to ensure that the certifying staff privileges valid in the Maldives before the entry into force of the applicable MCAR-66 licence category/subcategory and those of the converted MCAR-66 aircraft maintenance licence remain the same. Issue: 4.00 47 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements GM 66.A.70 Conversion provisions 1. As described in point 66.A.70, the conversion provisions apply to the holder of a valid certifying staff qualification issued by the CAA prior to the date of entry into force of MCAR- 66. The sentence “the holder of a valid certifying staff qualification issued by the CAA” means any person who had a qualification issued by the CAA allowing that person the performance of activities identical to the privileges of “certifying staff” contained in MCAR-66. This means that the signature of that person was sufficient to declare that the maintenance had been properly performed and the aircraft was ready for service and fit for flight in respect to such maintenance. 2. The conversion applies to “certifying staff qualifications” such as , for example: − holding a Maldivian licence (or completed the process to obtain such a licence); − having completed a qualification process defined by the CAA; − having completed the qualification requirements for certifying staff within a maintenance organisation, as defined in their procedures. This does not mean that in order to be entitled to a conversion process, the applicant has to be exercising certification privileges. A person may hold a “certifying staff qualification” while not having certification privileges (or while exercising very limited certification privileges below his/her qualification) for different reasons such as, for example, the following: - The person is working as “support staff” in the base maintenance environment; - The person has been authorised only for a very limited range of tasks (lower than what he/she would be entitled if his/her qualification is considered) since the person is working in a line station where the scope of tasks is very limited; - The person holds a licence with a wider scope than the scope of the organisation where he/she is employed; - The person is working outside the aviation industry or is temporarily on leave due to different reasons (medical, personal, etc). These persons are entitled to have the conversion performed in accordance with the full scope of their qualification and the full privileges that they would be entitled to hold on the basis of such qualification. 3. As described in point 66.A.70, certifying staff qualifications eligible for conversion are those valid “prior to the date of entry into force of MCAR-66”, which means those qualifications valid before 15 July 2007. Nevertheless, since the B3, B2L and L licences did not exist at those dates, certifying staff qualifications eligible for conversion to a B3, B2L and L licences are those valid before the Issue: 4.00 48 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements date where the CAA has the obligation to start issuing such licences, which means the following: − for the B3 licence, those qualifications valid before 31 December 2015; − for the B2L licence, those qualifications valid before 31 August 2021; − for the L licence, those qualifications valid before 31 August 2021. 4. (Reserved). 5. A certifying staff qualification can be subject to more than one conversion process and can also be converted to more than one licence (sub)category (with any applicable limitations). This could be the case, for example, of a person who already had the certifying staff qualification converted to a B1.2 licence with limitations linked to some missing elements of the MCAR-66 Appendix I and II standard (following 66.A.70(c)). This person would be entitled to apply and have his/her certifying staff qualification converted to a B1.2 or a B3 or L licence on the basis of 66.A.70(d), which would mean no need to compare with the MCAR-66 Appendix I and II standard, introducing only those limitations required in order to maintain the existing privileges. GM 66.A.70(c) Conversion provisions For example, a limitation could be where a person holds a pre-existing certifying staff qualification which covered, to the standard of MCAR-66 Appendix I and II, all the modules/subjects corresponding to the B1 licence except for electrical power systems. This person would be issued an MCAR-66 aircraft maintenance licence in the B1 category with a limitation (exclusion) on electrical power systems. For removal of limitations, refer to 66.A.50(c). GM 66.A.70(d) Conversion provisions For aircraft not used by air carriers licensed in accordance with MCAR-Air Operations other than complex motor-powered aircraft, an example of limitations could be where a person holds a pre-MCAR-66 qualification which covered privileges to release work performed on aircraft structures, powerplant, mechanical and electrical systems but excluded privileges on aircraft equipped with turbine engine, aircraft above 2 000 kg MTOM, pressurised aircraft and aircraft equipped with retractable landing gear. This person would be issued with a MCAR-66 aircraft maintenance licence in the B1.2 or B3 (sub)category with the following limitations (exclusions):

− aircraft used by air carriers licensed in accordance with MCAR- Air Operations (this limitation always exists); − aircraft above 2 000 kg MTOM; − pressurised aircraft; − aircraft equipped with retractable landing gear. Another example of limitations could be where a pilot-owner holds a pre-MCAR-66 qualification which covered privileges to release work performed on aircraft structures, powerplant, mechanical and electrical systems but limited to their own aircraft and limited to a particular Issue: 4.00 49 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Section A – Technical Requirements aircraft type (for example, a Cessna 172). This pilot-owner would receive a MCAR-66 aircraft maintenance licence in the B1.2 or B3 (sub)category with the following limitations (exclusions): − aircraft used by air carriers licensed in accordance with MCAR-Air Operations (this limitation always exists); − aircraft other than a Cessna 172; − aircraft not owned by the licence holder. One more example would be the case where a person holds a pre-MCAR-66 qualification that covers privileges to release work on composite and metal sailplanes and powered sailplanes, covering aircraft structures, powerplant, mechanical and electrical systems. This person would be issued a MCAR-66 aircraft maintenance licence in the L2 subcategory, with the following limitations (exclusions): − ELA1 aeroplanes; − wooden-structure aircraft covered with fabric; − aeroplanes with metal-tubing structure covered with fabric. And one more example would be the case where a person holds a pre-MCAR-66 qualification that covers privileges to release work on composite sailplanes up to the annual inspection but not including complex maintenance tasks, repairs and changes. This person would be issued a MCAR-66 aircraft maintenance licence in the L1C subcategory, with the following limitations: − complex maintenance tasks described in Appendix VII to MCAR-M, standard changes described in MCAR-21.A.90B, and standard repairs described in MCAR-21.A.431B. The essential aspect is that the limitations are established in order to maintain the privileges of the MCAR-66 qualification without comparing the previous qualification with the standard of MCAR-66 Appendix I and II. For removal of limitations, refer to MCAR-66.A.50(c).

The incorrect alternatives shall seem equally plausible to anyone ignorant of the subject. All of the alternatives shall be clearly related to the question and of similar vocabulary, grammatical construction and length. In numerical questions, the incorrect answers shall correspond to procedural errors such as corrections applied in the wrong sense or incorrect unit conversions: they shall not be mere random numbers. 1.2. Each multi-choice question must have three alternative answers of which only one must be the correct answer and the candidate shall be allowed a time per module which is based upon a nominal average of 75 seconds per question. 1.3. Each essay question requires the preparation of a written answer and the candidate shall be allowed 20 minutes to answer each such question. 1.4. Suitable essay questions shall be drafted and evaluated using the knowledge syllabus in Appendix I Module 7. 1.5. Each question will have a model answer drafted for it, which will also include any known alternative answers that may be relevant for other subdivisions. 1.6. The model answer will also be broken down into a list of the important points known as Key Points. 1.7. The pass mark for each module and sub-module multi-choice part of the examination is 75%. 1.8. The pass mark for each essay question is 75% in that the candidates answer shall contain 75% of the required key points addressed by the question and no significant error related to any required key point. 1.9. If either the multi-choice part only or the essay part only is failed, then it is only necessary to retake the multi-choice or essay part, as appropriate. 1.10. Penalty marking systems must not be used to determine whether a candidate has passed. 1.11. An examination in a module may not be retaken earlier than 90 days following the date of a failed examination in that module, except in the case of a maintenance training organisation approved in accordance with MCAR-147 which delivers a course of retraining tailored to the failed subjects in the particular module; the failed module may be retaken after 30 days.

Issue: 4.00 224 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the Regulations AMC to Appendix III to MCAR-66 ‘Aircraft Type Training and Examination Standard. On- the-Job Training’ Aircraft Type Training and On-the-Job Training The theoretical and practical training providers, as well as the OJT provider, may contract the services of a language translator in the case where training is imparted to students not conversant in the language of the training material. Nevertheless, it remains essential that the students understand all the relevant maintenance documentation. During the performance of examinations and assessments, the assistance of the translator should be limited to the translation of the questions, but should not provide clarifications or help in relation to those questions. AMC1 Appendix III “Aircraft type training and type evaluation standard- on-the-Job Training (OJT) Section 1 Aircraft Type Training 1. Aircraft type training may be sub-divided in airframe and/or powerplant and/or avionics/electrical systems type training courses. - Airframe type training course means a type training course including all relevant aircraft structure and electrical and mechanical systems excluding the powerplant. - Powerplant type training course means a type training course on the bare engine, including the build-up to a quick engine change unit. - The interface of the engine/airframe systems should be addressed by either airframe or powerplant type training course. In some cases, such as for general aviation, it may be more appropriate to cover the interface during the airframe course due to the large variety of aircraft that can have the same engine type installed. - Avionics/electrical systems type training course means type training on avionics and electrical systems covered by but not necessarily limited to ATA (Air Transport Association) Chapters 22, 23, 24, 25, 27, 31, 33, 34, 42, 44, 45, 46, 73 and 77 or equivalent. 2. Practical training may be performed either following or integrated with the theoretical elements. However, it should not be performed before theoretical training. 3. The content of the theoretical and practical training should: - address the different parts of the aircraft which are representative of the structure, the systems/components installed and the cabin; and - include training on the use of technical manuals, maintenance procedures and the interface with the operation of the aircraft. Issue: 4.00 225 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the Regulations Therefore it should be based on the following elements: - Type design including relevant type design variants, new technology and techniques; - Feedback from in-service difficulties, occurrence reporting, etc; - Significant applicable airworthiness directives and service bulletins; - Known human factor issues associated with the particular aircraft type; - Use of common and specific documentation, (when applicable, such as MMEL, AMM, MPD, TSM, SRM, WD, AFM, tool handbook), philosophy of the troubleshooting, etc.; - Knowledge of the maintenance on-board reporting systems and ETOPS maintenance conditions where applicable; - Use of special tooling and test equipment and specific maintenance practises including critical safety items and safety precautions; - Significant and critical tasks/aspects from the MMEL, CDL, Fuel Tank Safety (FTS), airworthiness limitation items (ALI) including Critical Design Configuration Control Limitations (CDCCL), CMR and all ICA documentation such as MRB, MPD, SRM, AMM, etc., when applicable. - Maintenance actions and procedures to be followed as a consequence of specific certification requirements, such as, but not limited to, RVSM (Reduced Vertical Separation Minimum) and NVIS (Night Vision Imaging Systems); - Knowledge of relevant inspections and limitations as applicable to the effects of environmental factors or operational procedures such as cold and hot climates, wind, moisture, sand, de-icing / anti-icing, etc. The type training does not necessarily need to include all possible customer options corresponding to the type rating described in the Appendix I to AMC to MCAR-66. 4. Limited avionic system training should be included in the category B1 type training as the B1 privileges include work on avionics systems requiring simple tests to prove their serviceability. 5. Electrical systems should be included in both categories of B1 and B2 type training. 6. The theoretical and practical training should be complementary and may be: - Integrated or split; Issue: 4.00 226 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the Regulations - Supported by the use of training aids, such as trainers, virtual aircraft, aircraft components, maintenance simulation training devices (MSTDs) and maintenance training devices (MTDs). 7. The integration and usage of MSTDs and MTDs, as defined in AMC 147.A.30(a), in maintenance type training (theoretical and/or practical) should consider the following: - The use of actual aircraft components should be allowed for any MSTD or MTD, even if the components are in a non-airworthy condition. - The complexity and degree of simulation for an MSTD may vary and should support type training elements that address a component, a system or the entire aircraft. Based on its characteristics and capabilities, the MSTD may be: − a training device capable of providing, for the respective component or system, the representation of aircraft location, access and layout, and for servicing with an acceptable level of accuracy and limited simulation; or − a training device capable of providing, for the respective component or system, the representation of aircraft location, access and layout with sufficient accuracy and with interactive simulation for servicing, and the applicable maintenance data for operational (O) and functional (F) test elements including built-in test (BIT) initiation and monitoring from outside the cockpit; such representation should have the capability to accommodate some troubleshooting scenarios; or − a training device capable of providing, for the respective component or system, the representation of onboard (flight deck/cockpit or cabin) indication and controls with an acceptable level of accuracy and limited interactive simulation; or − a training device capable of providing, for the respective component or system, the representation of onboard (flight deck/cockpit or cabin) indication and controls with sufficient accuracy and with interactive simulation for servicing, and the applicable maintenance data for operational (O) and functional (F) test elements including built- in test (BIT) initiation and monitoring; such representation should have the capability to accommodate some troubleshooting scenarios; or − any combination of the above. - Flight simulation training devices (FSTDs) may be used as MSTDs whenever their characteristics and capabilities are considered appropriate for, and supportive of, the delivery of the respective maintenance training element(s). - An MTD is any training device other than an MSTD used for maintenance training and/or examination and/or assessment. Issue: 4.00 227 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the Regulations AMC to Paragraphs 1(b), 3.2 and 4.2 of Appendix III to MCAR-66 ‘Aircraft Type Training and Examination Standard. On-the-Job Training’ Practical Element of the Aircraft Type Training 1. The practical training may include instruction in a classroom or in simulators but part of the practical training should be conducted in a real maintenance or manufacturer environment. 2. The tasks should be selected because of their frequency, complexity, variety, safety, criticality, novelty, etc. The selected tasks should cover all the chapters described in the table contained in paragraph 3.2 of Appendix III to MCAR-66. 3. The duration of the practical training should ensure that the content of training required by paragraph 3.2 of Appendix III to MCAR-66 is completed. Nevertheless, for aeroplanes with a MTOM equal or above 30000kg, the duration for the practical element of a type rating training course should not be less than two weeks unless a shorter duration meeting the objectives of the training and taking into account pedagogical aspects (maximum duration per day) is justified to the competent authority. 4. The organisation providing the practical element of the type training should provide trainees a schedule or plan indicating the list of tasks to be performed under instruction or supervision. A record of the tasks completed should be entered into a logbook which should be designed such that each task or group of tasks may be countersigned by the designated assessor. The logbook format and its use should be clearly defined. 5. In paragraph 4.2 of Appendix III to MCAR-66, the term ‘designated assessors appropriately qualified’ means that the assessors should demonstrate training and experience on the assessment process being undertaken and be authorised to do so by the organisation. Further guidance about the assessment and the designated assessors is provided in Appendix III to AMC to MCAR-66. 6. The practical element (for powerplant and avionic systems) of the Type Rating Training may be subcontracted by the approved MCAR-147 organisation under its quality system according to the provisions of 147.A.145(d)3 and the corresponding Guidance Material. AMC to Paragraph 1(c) of Appendix III to MCAR-66 ‘Aircraft Type Training and Examination Standard. On-the-Job Training’ Differences Training Approved difference training is not required for different variants within the same aircraft type rating (as specified in Appendix I to AMC to MCAR-66) for the purpose of type rating endorsement on the aircraft maintenance licence. However, this does not necessarily mean that no training is required before a certifying staff authorisation can be issued by the maintenance organisation (refer to AMC 66.A.20(b)3). Issue: 4.00 228 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the Regulations GM1 Appendix III Aircraft type training and type evaluation standard — on-the-job training (OJT) Section 1(c) DIFFERENCES TRAINING If the holder of a B1 and B2 licence, without any type rating, successfully completes a combined type training course (B1 + B2) followed by an OJT tailored only to B1 tasks, they can obtain only the type-rating endorsement that is applicable to the B1 subcategory. Within the next 3 years from the completion of the combined training course, endorsement of the aircraft type for the B2 category is possible after carrying out an OJT programme limited to the tasks relevant to the B2 category only. When instead, the aircraft type endorsement would be requested after more than 3 years, the applicant would be required to also pass a differences type training course (from B1 to B2) plus the OJT programme limited to the tasks relevant to the B2 category only. All common theoretical and practical elements, and OJT tasks, already demonstrated as B1, shall be considered fulfilled. AMC1 Appendix III Aircraft type training and type evaluation standard — on-the-job training (OJT) Section 3 AIRCRAFT TYPE TRAINING STANDARD Training methods are categorised as ‘instructor-centred’, ‘student-centred’ and ‘blended training’. The actual training method and the training tools should be adapted to suit the training subject and be chosen considering their intrinsic characteristics, such as but not limited to their efficiency and the pedagogical benefits of the method/tool. A complex or critical subject should not normally be taught solely through a student-centred method unless provisions are in place to verify the actual and progressive acquisition of knowledge of the student. Complex and critical areas should be identified by the training needs analysis (TNA). The complexity and criticality of the areas could differ on a case-by-case basis (that is, areas proven to be critical by organisations’ ‘in-service events’, occurrence reporting, human factors, safety, etc.), but should in any case cover the maintenance areas with special emphasis (MASE) identified by the type-certificate holder (TCH) in its operational suitability data (OSD). Issue: 4.00 229 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the Regulations AMC1 Appendix III Aircraft type training and type evaluation standard- on-the-Job Training (OJT) Section 3.1 (d) Training Needs Analysis (TNA) for the theoretical element of the aircraft type training 1. The minimum duration for the theoretical element of the type rating training course, as described in Appendix III to MCAR-66, has been determined based on: - generic categories of aircraft and minimum standard equipment fit - the estimated average duration of standard courses imparted in the world 2. The purpose of the Training Needs Analysis (TNA) is to adapt and justify the duration of the course for a specific aircraft type. This means that the TNA is the main driver for determining the duration of the course, regardless of whether it is above or below the minimum duration described in Appendix III to MCAR-66. In the particular case of type training courses approved on the basis of the requirements valid before Issue 2 of MCAR-66 was applicable (31 December 2015) and having a duration for the theoretical element equal to or above the minimum duration contained in paragraph 3.1(c) of Appendix III to MCAR-66, it is acceptable that the TNA only covers the differences introduced by Issue 2 of MCAR-66 in paragraph 3.1(e) “Content” and the criteria introduced in paragraph 3.1(d) “Justification of course duration” related to the minimum attendance and the maximum number of training hours per day. This TNA may result in a change in the duration of the theoretical element. 3. The content and the duration deriving from this TNA may be supported by an analysis from the Type Certificate holder. 4. In order to approve a reduction of such minimum duration, the CAA will perform an assessment on a case-by-case basis, and the assessment will be appropriate to the aircraft type and to the training methods and tools proposed. For example: (a) While it would be exceptional for a theoretical course for a large transport category aircraft, such as an A330 or a B777, to be below the minimum duration shown, it would not necessarily be exceptional in the case of a business aircraft, such as a Learjet 45 or similar. The TNA for a business aircraft course could demonstrate that a course of a shorter duration satisfies the applicable requirements. (b) The use of an MSTD (i.e. flat panel trainer) comprising aircraft-type-specific software may result in the duration of the training being reduced due to a more effective transfer of knowledge. (c) The use of multimedia-based training (MBT), or blending the training methods, may improve the efficiency of the training and, consequently, contribute to the reduction of the overall time needed to achieve the learning objectives. Issue: 4.00 230 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the Regulations 5. When developing the TNA, the following should be considered: (a) The TNA should include an analysis identifying all the areas and elements where there is a need for training as well as the associated learning objectives, considering the design philosophy of the aircraft type, the operational environment, the type of operations and the operational experience. This analysis should be written in a manner which provides a reasonable understanding of which areas and elements constitute the course in order to meet the learning objectives. (b) As a minimum, the Training Need Analysis (TNA) should take into account all the applicable elements contained in paragraph 3.1 of MCAR-66 Appendix III and associated AMCs. (c) The TNA should set-up the course content considering the Appendix III objectives for each level of training and the prescribed topics in the theoretical element table contained in paragraph 3.1 of MCAR-66 Appendix III. (d) For each chapter described in the theoretical element table contained in paragraph 3.1 of MCAR-66 Appendix III, the corresponding training time should be recorded. (e) Typical documents to be used in order to identify the areas and elements where there is a need for training typically include, among others, the Aircraft Maintenance Manual, MRB report, CMRs, airworthiness limitations, Troubleshooting Manual, Structural Repair Manual, Illustrated Parts Catalogue, Airworthiness Directives and Service Bulletins. (f) During the analysis of these documents: - Consideration should be given to the following typical activities: ▪ Activation/reactivation; ▪ Removal/Installation; ▪ Testing; ▪ Servicing; ▪ Inspection, check and repairs; ▪ Troubleshooting / diagnosis. - For the purpose of identifying the specific elements constituting the training course, it is acceptable to use a filtering method based on criteria such as: ▪ Frequency of the task; ▪ Human factor issues associated to the task; ▪ Difficulty of the task; ▪ Criticality and safety impact of the task; ▪ In-service experience; ▪ Novel or unusual design features (not covered by MCAR-66 Appendix I); ▪ Similarities with other aircraft types; Issue: 4.00 231 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the Regulations ▪ Special tests and tools/equipment. - It is acceptable to follow an approach based on: ▪ Tasks or groups of tasks, or ▪ Systems or subsystems or components (g) The TNA should: - Identify the learning objectives for each task, group of tasks, system, subsystem or component; - Associate the identified tasks to be trained to the regulatory requirements (table in Paragraph 3.1 of Appendix III to MCAR-66); - Organise the training into modules in a logical sequence (adequate combination of chapters as defined in Appendix III of MCAR-66); - Determine the sequence of learning (within a lesson and for the whole syllabus); - Identify the scope of information and level of detail with regard the minimum standard to which the topics of the TNA should be taught according to the set-up objectives. - Address the following: ▪ Description of each system/component including the structure (where applicable); ▪ System/component operation taking into account: a. Complexity of the system (e.g. the need of further break down into subsystems, etc.); b. Design specifics which may require more detailed presentation or may con- tribute to maintenance errors; c. Normal and emergency functioning; d. Troubleshooting; e. Interpretation of indications and malfunctions; f. Use of maintenance publications; g. Identification of special tools and equipment required for servicing and maintaining the aircraft; h. Maintenance Practices; i. Routine inspections, functional or operational tests, rigging/adjustment, etc. - Describe the following: ▪ The instructional methods and training tools and their blended application, in order to ensure the effectiveness of the training. Issue: 4.00 232 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the Regulations ▪ The maintenance training documentation/material to be delivered to the student. ▪ Facilitated discussions, questioning session, additional practiced-oriented training, etc. ▪ The homework, if developed, i.e. to support the achievement of the learning objectives while using asynchronous distance-learning or self-learning methods. ▪ The training provider’s resources available to the learner. (h) It is acceptable to differentiate between subjects which have to be led by an instructor and subjects which may be delivered through interactive simulation training devices and/or covered by self-paced elements. The overall time of the course will be allocated accordingly. (i) The maximum number of training hours per day for the theoretical element of type training should not be more than 6 hours. A training hour means 60 minutes of tuition excluding any breaks, examination, revision, preparation and aircraft visit. In exceptional cases, the CAA may allow deviation from this standard when it is properly justified that the proposed number of hours follows pedagogical and human factors principles. These principles are especially important in those cases where: - Theoretical and practical training are performed at the same time; - Training and normal maintenance duty / apprenticeship are performed at the same time. (j) The minimum participation time in order for the trainee to meet the objectives of the course should not be less than 90% of the tuition hours, or 95% completion of the content in case of student-centred methods in a theoretical training course. Additional training may be provided by the training organisation in order to meet the minimum participation time. If the minimum participation defined for the course is not met, a certificate of recognition should not be issued. (k) The TNA is a living process and should be reviewed/updated based on operation feedback, maintenance occurrences, airworthiness directives, major service bulletins impacting maintenance activities or requiring new competencies for mechanics, alert service bulletins, feedback from trainees or customer satisfaction, evolution of the maintenance documentation such as MRBs, MPDs, MMs, etc. The frequency at which the TNA should be reviewed/updated is left to the discretion of the organisation conducting the course. NOTE: The examination is not part of the TNA. However, it should be prepared in accordance with the learning objectives described in the TNA.

The OJT may be split in several parts and carried out at different AMOs, also combining line and base facilities from the same or different organisations. The organisation at which the final assessment is carried out, should control and coordinate the OJT activities and have the responsibility for the entire OJT programme. The procedures for the OJT should be included in the Exposition Manual of the approved maintenance organisation. ‘Skills and responsibilities of a typical certifying staff’ include but are not limited to: − understanding the importance of professional integrity, behaviour and having an appropriate attitude towards safety; − understanding the conditions for ensuring the continuing airworthiness of aircraft and components; − the ability to identify and rectify existing and potential unsafe conditions; − the ability to prioritise tasks, coordinate with a team, and report discrepancies; − the ability to determine the required qualifications for the performance of maintenance tasks; − the ability to confirm the proper accomplishment of maintenance tasks; − the ability to compile and control completed work cards; − knowledge of safety risks linked to a particular working environment; − understanding of human performance and limitations; − understanding of the AMO’s (where the OJT is performed) privileges and limitations; − understanding of the AMO’s personnel authorisations and limitations; − being familiar with the AMO’s documents/forms (work packages, work orders, work cards, etc.); Issue: 4.00 235 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the Regulations − being familiar with AMO’s release-to-service procedures: use of the aircraft technical logbook (ATLB), deferral of items and dispatch under MEL/CDL; − access, use and control of the required tools and equipment; − access, use and control of the required ICAs (AMM, TSM, SRM, etc.). OJT content and OJT logbook If the aircraft manufacturer has defined the OJT tasks during the type certification of a particular aircraft type (e.g. the operational suitability data (OSD) has been approved for a particular aircraft type), those tasks should be selected. In particular, the analysis performed for the maintenance areas of specific emphasis (MASE), as defined in point 430 of EASA CS-MCSD, helps the organisation identify the more appropriate tasks. Where no such data exists, the task list in Appendix II to the AMC to MCAR-66 serves as the basis to develop an OJT programme including the applicable tasks for a particular aircraft type, based typically on the AMM. The tasks may be selected from the table in Appendix II in order to cover a broader representative sample of both simple and complex tasks on the particular aircraft type in order to reach a balanced distribution of the tasks between line and base maintenance. The tasks should be selected among those that are applicable to the aircraft type and the licence (sub)category applied for; for example, the selection could exclude location tasks (LOC) and tasks that can be considered under the category A licence privileges (seat covers, boilers, wheels, etc.). A minimum number of tasks, as described in point 2 ‘List of tasks for OJT’ of Appendix II, of each of the following categories should be performed: INS/inspections, FOT/functional or operational, SGH/servicing, R/I removal and installation, MEL, and T/S troubleshooting. The licensing authority may accept that a limited number of tasks is not performed as long as the relevant cross section of the tasks as regards quality, quantity and complexity is still assured. A task may be performed on the analogous system installed on a different aircraft type when the systems are similar in terms of design architecture, technology, and functionality. This can be the case, for example, for tasks performed on engines or landing gear of aircraft of the same manufacturer. Such task should be clearly identified and recorded. Certain maintenance tasks could be performed on non-airworthy aircraft that still maintain functionality of systems to the extent that the maintenance tasks can be completely performed without any deviation from the maintenance instructions. Tasks circumscribed to system components may be performed at the workshop. This can be the case, for example, for avionics functional tests. Such scenarios should be limited to specific tasks that may not occur often in the maintenance of operational aircraft. The use of MSTDs and MTDs for OJT should be restricted to a minimum. Issue: 4.00 236 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the Regulations When an existing licence is changed to include an additional category with a type rating, a different OJT from the category held to the new one may be permissible.

In those cases, only tasks corresponding to the differences between the two categories should be performed. The organisation that has control over the OJT should provide candidates with a schedule or plan which indicates the list of tasks to be performed under supervision. A record of the completed tasks is to be entered into a logbook whose design and format should be such that each task or group of tasks is countersigned by the corresponding mentor(s). Regarding day-to-day supervision of the OJT programme in the approved maintenance organisation and the role of the mentor(s), the following should be considered: − It is sufficient for the completion of the individual OJT tasks to be confirmed by the direct mentor(s), without the direct evaluation of the assessor being necessary. − During the day-to-day OJT performance, the aim of the supervision is for mentors to oversee the whole process, including task completion, use of manuals, adherence to procedures, observance of safety measures, warnings, cautions and recommendations, and demonstration of appropriate behaviour in the maintenance environment. − The mentor(s) should personally observe the work being performed to ensure its safe completion, and should be readily available for consultation if needed during the OJT. − The mentor(s) should sign the tasks and release the maintenance tasks as the candidate is still not qualified to do so. − The mentor(s) should be designated by the approved maintenance organisation to supervise. For training in release-to-service procedures, following the completion of the performance of a specific task chosen by the mentor, the candidate should prepare a document with simulated release to service which has to be marked as ‘for training purposes only’ (e.g. ATL page, maintenance task card, CRS). If both the task and the simulated release to service have been performed to the satisfaction of the mentor, the task may be countersigned in the OJT task list by the mentor. A physical or electronic copy of the document with simulated release should be added to the syllabus. Tasks which are usually performed with more than one person may be performed by more than one candidate under the supervision of one mentor. During the performance of the tasks, the mentor is limited to overseeing three candidates at the same time, given that the candidates can be properly seen ‘at a glance’ from the mentor’s position. Those tasks should be marked as ‘group tasks’ when applying for the approval. All other tasks should be a one-to-one mentorship. In such cases, all the candidates involved should be noted on the work order. At the end of the performance of the OJT, a compliance report shall be made which verifies and documents the correct and complete performance and the recommendation of the mentor(s) Issue: 4.00 237 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the Regulations for the following assessment. The mentor(s) may deny a recommendation if the candidate has not demonstrated the knowledge, skills, behaviour and/or ethics required from certifying staff. Final assessment of the applicant The OJT assessment should consist of a theoretical part and a practical part. The theoretical part comprises the regulatory framework, safety procedures, knowledge of aircraft and its systems, maintenance procedures, and other typical certifying staff activities such as: − the review and acceptance of work orders; − shift-handover procedures and team coordination; − communication and interaction with the flight crew; − dispatch with unserviceable items; − clear aircraft logbook entries and reporting notes; − checks before release to service. The practical part should include maintenance tasks on the aircraft (e.g. rem./inst., TS, R/I, FOT, MEL dispatch). The assessor may decide to simulate some aspects of the maintenance tasks. The aircraft type on which the OJT is performed needs to be available for the assessment together with access to the required maintenance data, equipment, and tools. A training aircraft may be acceptable. It is good practice to assess the practical skills on the aircraft in question while the assessment of knowledge may be performed either on the aircraft or in theory. Further guidance about the designated assessors is provided in the AMC to Appendix III to MCAR-66. If an independent observer is required for the OJT, they shall be selected by the maintenance organisation among the maintenance personnel that have not taken part in the OJT performance but do have an adequate understanding of the OJT procedures.

The purpose of this Appendix is to establish the requirements for the assessment and approval by the CAA of any course that includes MBT in accordance with point 66.B.135. This Appendix may be used for the assessment of other training courses if the CAA decides that the assessment method laid down in this Appendix are appropriate for such other courses. The assessment will be conducted by the CAA against all the criteria laid down in Table (A), grouped in four categories from (a) to (d). The CAA will clearly identify in the table the MBT product being assessed and its production and update versions. 2. The CAA will put itself in the position of the student or the end user and will rate each criterion listed in Table (A) individually on a rating scale from 1 to 5, as follows: 1: Not acceptable. Does not meet the required criteria. 2: Partially acceptable, but improvement is needed to meet the required criteria. 3: Acceptable. Meets the required criteria. 4: Good. Meets the required criteria with enhancements made. 5: Excellent. Exceeds the required criteria. 3. If one or more of the criteria is rated below 3, an alternative learning process will be requested by the CAA in order to enhance the suitability of the product to an acceptable level. 4. Once the CAA has rated each of the individual criteria listed in Table (A) , the following combined rating scale will be used by the CAA to determine the overall suitability level for each MBT learning resource: − 100–80: Excellent learning resource. It offers different functionalities and meets the required suitability criteria. − 79–60: The learning resource meets the required suitability criteria. − 59–40: The learning resource does not allow for a sufficiently worthy educational use. It can be used for ‘informal’ training only. − 39–20: The learning resource is below the average. It does not meet several required suitability criteria. Before approving the product, the CAA will check that the final score of the MBT is equal to or above 60, and that there is no single criterion that is rated below 3.

The information complies with the current regulatory requirements. (ii) Relevance: the information is relevant to the learning objectives defined for the course. It supports the student in achieving the learning objectives. (b) Pedagogical quality The MBT emphasises the activities which promote the development of the required knowledge and skills. The main criteria for each product are related to three aspects: (i) Pedagogical formulation/construction: it is characterised by the quality of simplification, the presence of summaries as well as the use of diagrams, figures, animations, and illustrations. It evaluates whether the structure of the learning resource promotes its use in a pedagogical context. This refers to the ease of orientation (summary, lesson plan), presence of appropriate interactions, usability (back, forward, scroll boxes, etc.), and communication resources (questions and answers, FAQs, forum, etc.) (ii) Pedagogical strategies: teaching and learning styles should be based on active teaching approaches to build meaningful situations related to learning objectives and to learner motivation. (iii) Student assessment methods: methods are implemented to measure the achievement of learning objectives. (c) Didactic quality (i) Learning activities: the content refers to real-life situations the student could possibly face in an actual maintenance environment. (ii) Learning content: the content is adequate to meet the learning objectives. (d) Technical quality This section assesses the design, browsing and technological aspects of the learning resources: (i) Design: the content and organisation of the learning resource shall promote the appropriate use of colours, interactivity, graphic quality for selected images, animations, and illustrations.

The suggested choices or guidelines shall be clear and the groupings within the menus shall be consistent. (iii) Technological aspects: multimedia techniques aim to combine and exploit the capacities of any new technology in education to enhance the transfer of knowledge. Therefore, the system shall favour the use of animations, simulations, or any other interactive elements. Issue: 4.00 286 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the Regulations APPENDICES TO THE AMCs Issue: 4.00 287 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the Regulations Appendix I to AMC to MCAR-66 - Aircraft Type Ratings for MCAR-66 Aircraft Maintenance Licence The following aircraft type ratings will be used to ensure a common standard. Notes on type rating (TR) endorsement covering several models/variants: The endorsement of a type rating (TR) on the aircraft maintenance licence (AML), covering several models/variants, does not automatically imply that the AML holder has acquired the appropriate knowledge on each model/variant. In fact, the AML holder may only have received TR training and/or gained experience that was limited to one or several models or variants. To demonstrate adequate competence on the relevant model(s)/variant(s), the AML holder and/or the maintenance organisation where the AML holder is contracted/employed is (are) responsible to verify that the model/variant has been adequately covered by the TR course or gained experience and is up to date. Further explanation can be found in AMC 66.A.20(b)3 and AMC 145.A.35(a). Notes on when and how the licences will be modified: The CAA will implement the new type rating list once this Regulation becomes effective. New applications for type ratings that are no longer certified by CAA will not be accepted. Licences with the old type ratings will be endorsed with the amended type ratings, whenever the CAA deems necessary or the holder requests it; however, no later than the next renewal of the licence. Notes on aircraft modified by a Supplemental Type Certificate (STC): ▪ It is not the intention of this document to include all aircraft modified by STCs. ▪ When an aircraft has been modified by an STC for installation of another engine, the MCAR-66 type rating of this aircraft may change i.e. from Group 2 to Group 1. This is not reflected in this document. In case the applicant to a licence faces such a case, he/she can inform the CAA and a new type rating will be defined by the CAA. In the following tables: ▪ The column “TC Holder” includes the TC holder as defined in the TCDS (EASA, FAA or other) or the Specific Airworthiness Specifications (SAS). ▪ Some TC holders’ designations may include ‘Aircraft with an SAS’, this means that the aircraft listed under this TC holder designation is considered an ‘orphan aircraft’. ▪ In Group 3, the column ‘Type of structure’ intends to assist in identifying the experience required for this type with a view to removing existing limitations on the licence. ▪ In Group 4, the column ‘Type of structure’ intends to assist in identifying the required ‘L’ subcategories. Issue: 4.00 288 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the Regulations ▪ Wooden structure covered with fabric is considered to fall under wooden structure. For Aeroplanes with a combination of structures; e.g. metal tubing fuselage and wooden wings, both experience ‘metal tube covered with fabric’ and ‘wooden structure’ are required. ▪ In Group 3, the column ‘MTOM’ intends to assist in identifying the aeroplane types where the maximum take-off mass (MTOM) is: − above 2t requires a B1.2 and B2 or B2L licence, or − 2t and below requires a B1.2 or B3 and B2 or B2L licence. ▪ The column ‘NOTE’ includes some useful information, when relevant, e.g. ELA1 or ELA2 aircraft.

List of tasks for OJT The minimum list of tasks should be selected from the table below according to the following procedures and criteria: (i) Filter the ATA chapters (or sub-chapters, when required) applicable to the specific aircraft type (add others if they are missing). (ii) Identify relevant and significant tasks for each required category of INS, FOT, SGH, R/I, MEL and TS. (iii) Retain the required percentage for each task category, and throughout ATA chapters, as much as relevant to the particular aircraft type. The selection of tasks should give precedence to tasks which are critical and complex in terms of: − difficulty to execute; − interpretation of the maintenance procedures / work instructions; − specific tools and equipment; − coordination among maintenance staff (teamwork); − human factors (accessibility, human–machine interface (HMI), etc.); − safety impact on the aircraft and the crew. Removal and installation tasks include the final confirmation test, if required. Credit may be given for similar tasks between ATA systems (e.g. pneumatic valves in ATA 21, 30 and 36), but this should be kept to a minimum. Some tasks may be performed on another aircraft type as long as both the system and the task are similar. The following table provides an acceptable method of selection of OJT tasks for B1 and B2 AML categories, per ATA chapter or sub-chapters, as required by point 6.2(e) of Appendix III to MCAR- 66.

Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the AMC Appendix III Evaluation of the competence: assessment and assessors This Appendix applies to the competence assessment performed by the designated assessors (and their qualifications). 1) What does “competence” mean and areas of focus for assessment The assessment should aim at measuring the competence by evaluating three major factors associated to the learning objectives: ▪ Knowledge; ▪ Skills; ▪ Attitude; Generally, knowledge is evaluated by examination. The purpose of this document is not to describe the examination process: this material mainly addresses the evaluation of “skills” and “attitude” after training containing practical elements. Nevertheless, the trainee needs to demonstrate to have sufficient knowledge to perform the required tasks. “Attitude” is indivisible from the “skill” as this greatly contributes to the safe performance of the tasks. The evaluation of the competence should be based on the learning objectives of the training, in particular: ▪ the (observable) desired performance. This covers what the trainee is expected to be able to do and how the trainee is expected to behave at the end of the training; ▪ the (measurable) performance standard that must be attained to confirm the trainee’s level of competence in the form of tolerances, constraints, limits, performance rates or qualitative statements; and ▪ the conditions under which the trainee will demonstrate competence. Conditions consist of the training methods, the environmental, situational and regulatory factors. The assessment should focus on the competencies relevant to the aircraft type and its maintenance such as, but not limited to: ▪ Environment awareness (act safely, apply safety precautions and prevent dangerous situations); ▪ Systems integration (demonstrate understanding of aircraft systems interaction – identify, describe, explain, plan, execute); ▪ Knowledge and understanding of areas requiring special emphasis or novelty (areas peculiar to the aircraft type, domains not covered by MCAR-66 Appendix I, practical training elements that cannot be imparted through simulation devices, etc.); ▪ Using reports and indications (the ability to read and interpret); ▪ Aircraft documentation finding and handling (identify the appropriate aircraft documentation, navigate, execute and obey the prescribed maintenance procedures); Issue: 4.00 351 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the AMC ▪ Perform maintenance actions (demonstrate safe handling of aircraft, engines, components and tools); ▪ Aircraft final/close-up and report (apply close up, initiate appropriate actions/follow- up/records of testing, establish and sign maintenance records/logbooks). 2) How to assess As far as feasible, the objectives of the assessment should be associated with the learning objectives and the passing level; it means that observable criteria should be set in order to measure the performance and should remain as objective as possible. The general characteristics of effective assessment are: objective, flexible, acceptable, comprehensive, constructive, organised and thoughtful. At the conclusion, the trainee should have no doubt about what he/she did well, what he/she did poorly and how he/she can improve. The following is a non-exhaustive list of questions that may be posed to assist assessment: ▪ What are the success factors for the job? ▪ What are typical characteristics of a correct behaviour for the task? ▪ What criteria should be observed? ▪ What level of expertise is expected? ▪ Is there any standard available? ▪ What is the pass mark? For example: o “Go-no go” situation; o How to allocate points? Minimum amount to succeed; o “Must know or execute” versus “Good to know or execute” versus “Don’t expect the candidate to be an expert”. ▪ Minimum or maximum time to achieve? Use time effectively and efficiently. ▪ What if the trainee fails? How many times is the trainee allowed to fail? ▪ When and how should the trainee be prepared for the assessment? ▪ What proportion of judgment by the instructor out of collaboration with the trainee is needed during the evaluation stage? The assessment may be: ▪ diagnostic (prior to a course), formative (re-orientate the course on areas where there is a need to reinforce) or summative (partial or final evaluation); ▪ performed task-by-task, as a group of tasks or as a final assessment; One method might be an initial assessment to be performed by the trainee himself, then discussing areas where the perceptions of the trainee’s performance by the assessors differ in order to: ▪ develop the self-assessment habits; ▪ make the assessment more acceptable and understandable to both parties. Issue: 4.00 352 24 April 2025 Maldivian Civil Aviation Regulations MCAR-66 – Certifying Staff Maldives Civil Aviation Authority Appendices to the AMC A “box-ticking” exercise would be pointless. Experience has shown that assessment sheets have largely evolved over time into assessment of groups of “skills” because in practice such things eventually detracted from the training and assessment that it was intended to serve: evaluate at a point of time, encourage and orientate the training needs, improve safety and ultimately qualify people for their duties. In addition, many other aspects should be appropriately considered during the assessment process such as stress and environmental conditions, difficulty of the test, history of evaluation (such as tangible progresses or sudden and unexpected poor performance made by the trainee), amount of time necessary to build competence, etc. All these reasons place more emphasis on the assessor and highlight the function of the organisation’s approval. 3) Who should assess In order to qualify, the assessor should: ▪ Be proficient and have sufficient experience or knowledge in: o human performance and safety culture; o the aircraft type (necessary to have the certifying staff privileges in case of CRS issuances); o training/coaching/testing skills; o instructional tools to use; ▪ Understand the objective and the content of the practical elements of the training that is being assessed; ▪ Have interpersonal skills to manage the assessment process (professionalism, sincerity, objectivity and neutrality, analysis skills, sense of judgement, flexibility, capability of evaluating the supervisor’s or instructor’s reports, handling of trainee’s reactions to failing assessment with the cultural environment, being constructive, etc.); ▪ Be ultimately designated by the organisation to carry out the assessment. The roles may be combined for: ▪ the assessor and the instructor for the practical elements of the Type Rating Training; or ▪ the assessor and the supervisor for the On-the-Job Training. provided that the objectives associated to each role are clearly understood and that the competence and qualification criteria according to the company’s procedures are met for both functions. Whenever possible (depending on the size of the organisation), it is recommended to split the roles (two different persons) in order to avoid any conflicts of interests. When the functions are not combined, the role of each function should be clearly understood. _____________________ Issue: 4.00 353 24 April 2025
