(b) Aircraft operated under Part-NCO by its owner together with an ATO or a DTO flight instructor for the purpose of training, when the contract between the owner and the training organisation and the procedures of the training organisation allow it. The continuing airworthiness of such aircraft remains under the responsibility of the owner, or of the CAMO or CAO contracted by the owner, if the owner has elected to contract a CAMO or CAO in accordance with ML.A.201(f). (c) Aircraft used for very limited training flights due to the specific configuration of the aircraft and limited need for such flights. Issue: 1.00 7 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements GM1 ML.A.201(f) Responsibilities If an owner (see definition in point ML.1(c)(3)) decides not to make a contract with a CAMO or CAO, the owner is fully responsible for the proper accomplishment of the corresponding continuing airworthiness management tasks. As a consequence, it is expected that the owner properly and realistically self-assesses his or her own competence to accomplish those tasks or otherwise seek the necessary expertise. GM1 ML.A.201(h) Responsibilities USE OF AIRCRAFT INCLUDED IN AN AOC FOR NON-COMMERCIAL OPERATIONS OR SPECIALISED OPERATIONS As point (h) is not a derogation, points ML.A.201(e) and (f) are still applicable. Therefore, the management of continuing airworthiness of the aircraft by the CAMO or CAO of the AOC holder means that the other operator has established a written contract as per Appendix I to MCAR-ML with this CAMO or CAO. MCAR-ML.A.202 Occurrence reporting (a) Without prejudice to the reporting requirements set out in MCAR-145 and MCAR-CAMO, any person or organisation responsible in accordance with point ML.A.201 shall report any identified condition of an aircraft or component which endangers flight safety to: (1) the CAA; (2) to the organisation responsible for the type design or supplemental type design. (b) The reports referred to in point (a) shall be made in a manner determined by the CAA and shall contain all pertinent information about the condition known to the person or organisation making the report. (c) Where the maintenance or the airworthiness review of the aircraft is carried out on the basis of a written contract, the person or the organisation responsible for those activities shall also report any condition referred to in point (a) to the owner of the aircraft and, when different, to the CAMO or CAO concerned. (d) The person or organisation shall submit the reports referred to in points (a) and (c) as soon as possible, but no later than 72 hours from the moment when the person or organisation identified the condition to which the report relates, unless exceptional circumstances prevent this. AMC1 ML.A.202 Occurrence reporting Issue: 1.00 8 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements Accountable persons or organisations should ensure that the design approval holder (DAH) receives adequate reports of occurrences for that aircraft or component, to enable the DAH to issue appropriate service instructions and recommendations to all owners or operators. Accountable persons or organisations should establish a liaison with the DAH to determine whether published or proposed service information will resolve the problem or to obtain a solution to a particular problem. MCAR-13B provides further details on occurrence reporting. Issue: 1.00 9 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements Subpart C — CONTINUING AIRWORTHINESS MCAR-ML.A.301 Continuing airworthiness tasks The aircraft continuing airworthiness and the serviceability of both operational and emergency equipment shall be ensured by: (a) the accomplishment of pre-flight inspections; (b) the rectification of any defect and damage affecting safe operation in accordance with data specified in points ML.A.304 and ML.A.401, as applicable, while taking into account the minimum equipment list (‘MEL’) and configuration deviation list, when they exist; (c) the accomplishment of all maintenance in accordance with the AMP referred to in point ML.A.302; (d) the accomplishment of any applicable: (1) airworthiness directive (‘AD’); (2) operational directive with a continuing airworthiness impact, (3) continuing airworthiness requirement established by the CAA and the State of Design, (4) measures mandated by the CAA in immediate reaction to a safety problem; (e) the accomplishment of modifications and repairs in accordance with ML.A.304; (f) maintenance check flights, when necessary. Issue: 1.00 10 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements GM1 ML.A.301(f) Continuing airworthiness tasks MAINTENANCE CHECK FLIGHTS (MCFs) (a) The definition of and operational requirements for MCFs are laid down in the MCAR-Air Operations and are carried out under the control and responsibility of the aircraft operator. During the flight preparation, the flight and the post-flight activities as well as for the aircraft handover, the processes requiring the involvement of maintenance personnel or organisations should be agreed in advance with the operator. The operator should consult as necessary with the person or organisation in charge of the airworthiness of the aircraft. (b) Depending on the aircraft defect and the status of the maintenance activity performed before the flight, different scenarios are possible and are described below: (1) The aircraft maintenance manual (AMM), or any other maintenance data issued by the DAH, requires that an MCF be performed before completion of the maintenance ordered. In this scenario, a certificate after incomplete maintenance, when in compliance with ML.A.801(f) or MCAR-145.A.50(e), should be issued and the aircraft can be flown for this purpose under its airworthiness certificate. Due to incomplete maintenance, it is advisable to open a new entry into the ML.A.305 aircraft logbook, to identify the need for an MCF. This new entry should contain or refer to, as necessary, data relevant to perform the MCF, such as aircraft limitations and any potential effect on operational and emergency equipment due to incomplete maintenance, maintenance data reference and maintenance actions to be performed after the flight. After a successful MCF, the maintenance records should be completed, the remaining maintenance actions finalised and a certificate of release to service (CRS) issued. (2) Based on its own experience and for reliability considerations and/or quality assurance, an operator, owner, CAO or CAMO may wish to perform an MCF after the aircraft has undergone certain maintenance while maintenance data does not call for such a flight. Therefore, after the maintenance has been properly carried out, a CRS is issued and the aircraft airworthiness certificate remains valid for this flight. (3) After troubleshooting of a system on the ground, an MCF is proposed by the maintenance personnel or organisation as confirmation that the solution applied has restored the normal system operation. During the maintenance performed, the maintenance instructions are followed for the complete restoration of the system and therefore a CRS is issued before the flight. The airworthiness certificate is valid for the flight. An open entry requesting this flight may be recorded in the aircraft logbook. (4) An aircraft system has been found to fail, the dispatch of the aircraft is not possible in accordance with the maintenance data, and the satisfactory diagnosis of the cause of the fault can only be made in flight. The process for this troubleshooting is not described in the maintenance data and therefore scenario (1) does not apply. Since the aircraft cannot Issue: 1.00 11 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements fly under its airworthiness certificate because it has not been released to service after maintenance, a permit to fly issued in accordance with MCAR-21 is required. After the flight and the corresponding maintenance work, the aircraft can be released to service and continue to operate under its original certificate of airworthiness. (c) For certain MCFs, the data obtained or verified in flight will be necessary for assessment or consideration after the flight by the maintenance personnel or organisation prior to issuing the maintenance release. For this purpose, when the maintenance staff cannot perform these functions in flight, it may rely on the crew performing the flight to complete this data or to make statements about in-flight verifications. In this case, the maintenance staff should appoint the crew personnel to play such a role on their behalf and, before the flight, brief the appointed crew personnel on the scope, functions and the detailed process to be followed, including required reporting information after the flight and reporting means, in support of the final release to service to be issued by the certifying staff. Issue: 1.00 12 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements MCAR-ML.A.302 Aircraft Maintenance programme (a) Maintenance of each aircraft shall be organised in accordance with an AMP. (b) The AMP and any subsequent amendments thereto shall be, alternatively: (1) declared by the owner in accordance with ML.A.302(c)(7), where the continuing airworthiness of the aircraft is not managed by a CAMO or CAO; (2) approved by the CAMO or CAO responsible for managing the continuing airworthiness of the aircraft. The owner declaring the AMP in accordance with point (b)(1) or the organisation approving the AMP in accordance with point (b)(2) shall keep the AMP updated. (c) The AMP: (1) shall clearly identify the owner of the aircraft and the aircraft to which it relates, including any installed engine and propeller, as applicable; (2) shall include, alternatively: (a) the tasks or inspections contained in the applicable minimum inspection programme (‘MIP’) referred to in point (d); (b) the instructions for continuing airworthiness (‘ICA’) issued by the design approval holder (‘DAH’); (3) may include additional maintenance actions to those referred to in point (c)(2) or maintenance actions alternative to those referred to in point (c)(2)(b) at the proposal of the owner, CAMO or CAO, once approved or declared in accordance with point (b).

If the review shows deficiencies of the aircraft linked with deficiencies in the content of the AMP, the AMP shall be amended accordingly. In this case the person performing the review shall inform the CAA if he does not agree with the measures amending the AMP taken by the owner, CAMO or CAO. The CAA shall decide which amendments to the AMP are necessary, raising the corresponding findings and, if necessary, reacting in accordance with point ML.B.304. (d) A MIP: (1) shall contain the following inspection intervals: (a) for aeroplanes, touring motor gliders (‘TMGs’) and balloons, every annual or 100- h interval, whichever comes first, to which a tolerance of 1 month or 10 h may be Issue: 1.00 14 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements applied.

(f) If the conditions provided for in points (e)(1) to (e)(4) are met, the AMP applicable to the aircraft shall consist of the following: (1) the ICA issued by the DAH; (2) the maintenance recommendations, such as TBO intervals, issued through service bulletins, service letters, and other non-mandatory service information; Issue: 1.00 16 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements (3) the mandatory continuing airworthiness information, such as repetitive ADs, the ALS of the ICA and specific maintenance requirements contained in the TCDS; (4) the tasks due to specific operational or airspace directives or requirements in relation to particular instruments and equipment. AMC1 ML.A.302 Aircraft maintenance programme (a) The aircraft should only be maintained according to one maintenance programme at a given point in time. Where an owner wishes to change from one programme to another (e.g. from an AMP based on minimum inspection programme (MIP) to an AMP based on DAH’s data), certain additional maintenance may need to be carried out on the aircraft to implement this transition. (b) The maintenance programme may take the format of the standard template provided in AMC2 ML.A.302 (CAA Form AMP). This maintenance programme may include several aircraft registrations as long as the maintenance requirements for each registration are clearly identified.

CAA Form AMP, Issue 1, 15 November 2021 Issue: 1.00 21 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements GM1 ML.A.302 Aircraft maintenance programme The responsibilities associated with maintenance programmes developed in accordance with ML.A.302 are the following: (a) If the owner has contracted a CAMO or CAO in order to manage the continuing airworthiness of the aircraft, this organisation is responsible for developing and approving a maintenance programme which: (1) indicates whether this programme is based on data from the DAH or on the MIP described in ML.A.302(d);

(2) identifies the owner and the specific aircraft, engine, and propeller (as applicable); (3) includes all mandatory continuing airworthiness information and any additional tasks derived from the assessment of the DAH’s instructions; (4) justifies any deviations from the DAH’s instructions; when the DAH’s instructions are the basis for the AMP development, these deviations should not fall below the requirements of the MIP; and (5) is customised to the particular aircraft type, configuration and operation, in accordance with ML.A.302(c)(5). (b) If the owner has not contracted a CAMO or CAO in order to manage the continuing airworthiness of the aircraft, then the owner is responsible for developing and declaring the maintenance programme, assuming full responsibility for its content, and for any deviations from the DAH’s instructions (ref. ML.A.201(f) and ML.A.302(c)(7)) and the possible consequences of such deviations. In this case, these deviations do not need to be justified, but are to be identified in the AMP. However, the maintenance programme still needs to comply with the requirements contained in ML.A.302(c), in particular with the obligation to not fall below the requirements of the MIP and to comply with the mandatory continuing airworthiness information. (c) The content of the owner-declared maintenance programme cannot be challenged up front either by the CAA or by the contracted maintenance organisation. This declared maintenance programme is the basis for adequate planning of maintenance, as well as for the ARs and the aircraft continuing airworthiness monitoring (ACAM) inspections in accordance with ML.B.303. Nevertheless, the maintenance programme will be subject to periodic reviews at the occasion of the AR and, in case of discrepancies, linked with deficiencies in the content of the maintenance programme, the owner shall amend the maintenance programme accordingly, as required by ML.A.302(c)(9). (d) When the CAA is notified of deficiencies linked with the content of the declared maintenance programme for a particular aircraft (in case no agreement is reached between the owner and the AR staff about the changes required in the maintenance programme), the CAA will contact the owner, request a copy of the maintenance Issue: 1.00 22 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements programme, decide which amendment to the AMP is necessary and raise the associated finding (ref. ML.A.302(c)(9)). If necessary, the CAA may also react in accordance with ML.B.304. Based on the information received, the reported deficiencies and the identified risks, the CAA may in addition adapt the ACAM programme accordingly (ref. ML.B.303). (e) Although there is no requirement for the owner to send a copy of the maintenance programme to the CAA, this does not prevent the CAA from requesting at any time the owner to send information about, or a copy of the AMP, even if deficiencies have not been reported (see AMC1 ML.B.201). (f) Since the maintenance programme has to identify the alternatives tasks to the DAH’s instructions, the ARs and ACAM inspections can place emphasis on the inspection of the areas affected by those deviations in order to make sure that the maintenance programme is effective. (g) Since the CAA is not responsible for the content of a declared maintenance programme, the CAA does not authorise the accomplishment of the scheduled maintenance to deviate from the AMP content (other than the tolerances provided for in ML.A.302(d)(1)). In such cases, the owner may declare an amended AMP. GM2 ML.A.302 Aircraft Maintenance Programme The following table provides a summary of the provisions contained in ML.A.302 in relation to the content of the maintenance programme, its approval and its link with the AR: OPTION 1 OPTION 2 Responsibility for Contracted CAMO or CAO Owner (if allowed under developing the AMP ML.A.201(f)) Approval/declaration of the Approved by the CAMO or Declaration by the owner or maintenance programme CAO, or none required in case none required in case of of compliance with MCAR- compliance with MCAR- ML.A.302(e) ML.A.302(e) Basis for the maintenance MIP (not applicable to rotorcraft and airships) or ICA issued by programme the DAH Deviations from the DAH’s Deviations from the DAH’s Deviations do not need to be ICA instructions are justified. The justified. CAMO/CAO keeps a record of the justifications and provides a copy of them to the owner. AMP annual review In conjunction with the AR, by the AR staff or, if not performed in conjunction with the AR (e.g. in case of ARC extension), by the CAMO or CAO. AMC1 ML.A.302(c) Aircraft Maintenance Programme When evaluating an alternative to a maintenance task issued or recommended by the DAH, such Issue: 1.00 23 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements as the extension of TBO intervals, or when considering not to include a maintenance task issued or recommended by the DAH, a risk-based approach should be taken, considering aspects such as the operation of aircraft, type of aircraft, hours and years in service, maintenance of the aircraft, compensating measures, redundancy of components, etc. The following table provides more details of aspects that should be considered: Examples OPS approval HIGHER RISK: commercial operation, commercial flight training MEDIUM RISK: flight training by an association, non- commercial specialised operations (SPO) LOWER RISK: private Flight rules HIGHER RISK: instrument flight rules (IFR) MEDIUM RISK: visual flight rules (VFR) at night LOWER RISK: VFR by day Aircraft weight HIGHER RISK: Other than ELA1 MEDIUM RISK: ELA1 aircraft other than light sport aeroplanes (LSA), very light aircraft (VLA), sailplanes and powered sailplanes LOWER RISK: LSA, VLA, sailplanes and powered sailplanes Who manages the HIGHER RISK: owner airworthiness of the LOWER RISK: CAMO/CAO aircraft?

It may also be useful for the owner in order to take an informed decision before introducing deviations from the DAH’s recommendations. Nevertheless, as allowed by MCAR-ML.A.302(c)(7) and explained in GM ML.A.302, when the owner issues a declaration for the maintenance programme, they do not need to justify such deviations. AMC1 ML.A.302(c)(9) Aircraft Maintenance Programme ANNUAL REVIEW OF AMP (a) During the annual review of the maintenance programme, as required by point ML.A.302(c)(9), the following should be taken into consideration: (1) the results of the maintenance performed during that year, which may reveal that the current maintenance programme is not adequate; (2) the results of the AR performed on the aircraft, which may reveal that the current maintenance programme is not adequate; (3) revisions introduced on the documents affecting the programme basis, such as the ML.A.302(d) MIP or the DAH’s data; (4) changes in the aircraft configuration, and type and specificity of operation; (5) changes in the list of pilot-owners; and (6) applicable mandatory requirements for compliance with MCAR-21, such as airworthiness directives (ADs), airworthiness limitations, certification maintenance requirements and specific maintenance requirements contained in the type certificate data sheet (TCDS). (b) When reviewing the effectiveness of the AMP, the AR staff (or the CAMO/CAO staff if the review of the AMP is not performed in conjunction with an AR) may need to review the maintenance carried out during the last 12 months, including unscheduled maintenance. To this end, he or she should receive the records of all the maintenance performed during that year from the owner/CAMO/CAO. (c) When reviewing the results of the maintenance performed during that year and the results of the AR, attention should be paid as to whether the defects found could have been prevented by introducing in the maintenance programme certain DAH’s recommendations, which were initially disregarded by the owner, CAMO or CAO. Issue: 1.00 25 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements GM1 ML.A.302(c)(2)(b) Aircraft maintenance programme ‘DAH’ refers to the holder of a type certificate (TC), restricted type certificate, supplemental type certificate (STC), Technical Standard Order (TSO) authorisation / European Technical Standard Order (ETSO) authorisation, repair or change to the type design. The ‘instructions for continuing airworthiness (‘ICA’) issued by the design approval holder (‘DAH’)’ do not include the data issued by other original equipment manufacturer (OEM), except when the DAH’s ICA makes clear reference to such OEM data. Tasks or intervals (e.g. escalations) alternative to those of the DAH’s ICA and selected by the CAMO or CAO for the AMP do not need to be approved by the CAA. Justification of these deviations are to be kept by the CAMO or CAO. GM1 ML.A.302(c)(3) Aircraft maintenance programme ALTERNATIVE MAINTENANCE ACTIONS ‘Maintenance actions alternative to those referred to in point (c)(2)(b)’ refer to when the DAH’s ICA are used as the basis for the AMP development and the CAMO, CAO or owner (as applicable), when developing the AMP, decides to deviate from certain of these DAH’s instructions, introducing, for example, a less frequent interval or a different task type (inspection instead of check) than the one established by the ICA. These alternative maintenance actions shall not be less restrictive than those set out in the applicable MIP. This means that the extent of the maintenance to be covered by the deviating task cannot be less than the extent of the corresponding task in the MIP in terms of frequency and task type. Examples of alternative maintenance actions: ICA task AMP proposed MIP task Alternative alternative acceptable Yes/No Inspection XX Inspection XX Inspection XX Yes 6 months interval 12 months interval 12 months interval Inspection XX Inspection XX Inspection XX No 12 months interval 24 months interval 12 months interval Inspection XX Inspection XX Inspection XX No 24 months interval 36 months interval 12 months interval (24 months to be kept) Functional test Operational test Functional test No* system XX system XX (same system XX (same interval) or general interval) visual inspection system XX (same interval) Issue: 1.00 26 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements Operational test Functional test Operational test Yes* system XX system XX (same system XX (same interval) interval) Inspection XX Inspection XX None relevant Yes 24 months interval 36 months Functional test General visual None relevant Yes inspection *A functional test is considered more restrictive than an operational test. Remark: the above does not apply to one-time interval extensions, for which ML.A.302(d)(1) provides 1-month or 10-h tolerance (i.e. permitted variation) for aeroplanes, touring motor gliders (TMGs) and balloons and 1-month tolerance for sailplanes and powered sailplanes other than TMGs. GM1 ML.A.302(c)(4) Aircraft maintenance programme MANDATORY CONTINUING AIRWORTHINESS INFORMATION OTHER THAN ADS ‘Mandatory continuing airworthiness information’ other than ADs may be different from one aircraft to another, depending on the type certification basis used. The aircraft may have been certified before the term ‘ALS (Airworthiness Limitations Section)’ was introduced in the certification specification (or airworthiness code). However, the intent is that the AMP (whether based on MIP or not) includes all mandatory scheduled maintenance requirements identified during the initial airworthiness activity, by the TC holder, STC holder and, if applicable, engine TC holder. These requirements may be identified under a variety of designations such as: — Airworthiness limitations or Airworthiness limitation items (ALI) — Certification maintenance requirements (CMR) — Safe life items or safe life limits or safe life limitations — Life-limited parts (LLP) — Time limits — Retirements life — Mandatory Inspections or Mandatory Airworthiness Inspections — Fuel airworthiness limitations or Fuel tank safety limitations In case of doubt, it is advised to check the TCDS or contact the DAH. The intervals of the mandatory continuing airworthiness information cannot be extended by a CAMO/CAO. The escalation of such tasks is to be approved by the Agency. AMC1 ML.A.302(d) Aircraft maintenance programme Issue: 1.00 27 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements This AMC contains an acceptable MIP for aeroplanes of 2730 kg maximum take-off mass (MTOM) and below, and for ELA2 aircraft other than airships, grouped in the following categories: — aeroplanes of 2730 kg MTOM and below; — ELA2 sailplanes and ELA2 powered sailplanes; and — ELA2 balloons. These MIPs already comply with the requirements of ML.A.302(d) and may be used in order to define the basic information for the maintenance programme as required by ML.A.302(c)(2)(a). However, the maintenance programme must be customised as required by ML.A.302(c)(5), which may be achieved by using the standard template contained in AMC ML.A.302. It should be noted that using the 1-month tolerance permitted by ML.A.302(d)(1) for the annual inspection may result in an expired ARC. MIP for aeroplanes of 2730 kg MTOM and below To be performed at every annual/100-h interval, whichever comes first. A tolerance of 1 month or 10 h may be applied. The next interval shall be calculated from the time the inspection takes place. Note 1: Use the manufacturer’s maintenance manual to accomplish each task/inspection. Note 2: Proper operation of backup or secondary systems and components should be performed wherever a check for improper installation/operation is carried out.

However, if doing so, he or she has the obligation to receive the agreement of the owner, or the contracted CAMO or CAO. The term ‘required’ refers to equipment that is required by the applicable airworthiness code (certification specification) or required by the relevant regulations for air operations or the applicable rules of the air or as required by air traffic management (e.g. a transponder in certain controlled airspace). AMC1 ML.A.403(d) Aircraft defects All deferred defects should be made known to the pilot/flight crew, whenever possible, prior to their arrival at the aircraft. Deferred defects should be listed on the current list of deferred maintenance (ML.A.305(d)(6)) and rectified at the next appropriate maintenance event and within the limit specified in the maintenance data. Any deferred defect that is not rectified during the next maintenance event, should be re-entered on the list of deferred maintenance and the original date of the defect should be retained.

Issue: 1.00 50 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements GM1 ML.A.501 Classification and installation Components accepted by the owner in accordance with MCAR-21.A.307(c) of MCAR-21, or standard parts are eligible for installation without a CAA Form 1. AMC1 ML.A.501(a)(ii) Classification and installation CAA FORM 1 OR EQUIVALENT Refer to AMC1 M.A.501(a)1. AMC1 ML.A.501(e) Classification and installation BALLOONS Baskets, burners and fuel cylinders are components which are often interchanged between different balloons. Furthermore, they are often removed/installed by the pilot-owner (or by other persons when such removal/installation is not considered maintenance because the task is described in the AFM). As a consequence, a CAA Form 1 does not need to be issued when these components are removed in serviceable condition from a balloon, and can be installed on another balloon as long as the person performing the installation has access to the appropriate maintenance records necessary to establish their serviceable condition. In particular, due attention should be paid to the inspection dates of the various components. This does not supersede the requirement to release any maintenance performed on such components either on a CAA Form 1 or equivalent or on the balloon maintenance log book, as applicable. MCAR-ML.A.502 Component maintenance (a) Components accepted by the owner in accordance with point (c) of point MCAR-21.A.307 of MCAR-21 shall be maintained by any person or organisation, subject to reacceptance by the owner under the conditions of point MCAR-21.A.307(c) of MCAR-21. This maintenance is not eligible for the issuance of a CAA Form 1, as set out in Appendix II of MCAR-M, and shall be subject to the aircraft release requirements. (b) Components shall be released in accordance with the following table: Released using a CAA Form 1 (as Released at aircraft level per set out in Appendix II of MCAR-M) point ML.A.801 (not possible to issue a CAA Form 1) Components maintained in accordance with component maintenance data (data issued by the component manufacturer) Maintenance other than Engine-rated (for engine) or (i) Aircraft-rated maintenance overhaul component-rated (for other organisations; and/or Issue: 1.00 51 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements components) maintenance (ii) independent certifying staff organisations Overhaul of components Component-rated maintenance Not possible other than engines and organisations propellers Overhaul of engines and Engine-rated (for engine) or (i) Aircraft-rated maintenance propellers for CS-VLA, CS-22 component-rated (for propeller) organisations; and/or and LSA aircraft maintenance organisations (ii) independent certifying staff Overhaul of engines and Engine-rated (for engine) or Not possible propellers for other than CS- component-rated (for propeller) VLA, CS-22 and LSA aircraft maintenance organisations Components maintained in accordance with aircraft maintenance data (data issued by the aircraft manufacturer) All components and all types Engine-rated (for engine) or - Aircraft-rated maintenance of maintenance component-rated (for other organisations; and/or components) maintenance - independent certifying staff organisations GM1 ML.A.502 Component maintenance COMPONENT MAINTENANCE BY INDEPENDENT CERTIFYING STAFF The cases where the independent certifying staff can release component maintenance are only valid when the independent certifying staff is allowed, according to ML.A.201, to carry out maintenance (refer to GM1 ML.A.201) and when he or she is competent for such component maintenance. As an example, in accordance with ML.A.201(e), the independent certifying staff cannot carry out maintenance when the balloon is operated commercially. MCAR-ML.A.503 Service-life-limited components (a) The term ‘service life-limited components’ contains the following components: (1) components subject to a certified life limit after which the components should be retired, and; (2) components subject to a service life limit after which the components shall undergo maintenance to restore their serviceability. (b) Installed service-life-limited components shall not exceed the approved service life limit as specified in the AMP and ADs, except as provided for in point ML.A.504(c). (c) The approved service life is expressed in calendar time, flight hours, landings or cycles, as appropriate. (d) At the end of the approved service life limit, the component must be removed from the Issue: 1.00 52 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements aircraft for maintenance, or for disposal in the case of components with a certified life limit. MCAR-ML.A.504 Control of unserviceable components (a) A component shall be considered unserviceable in any of the following circumstances: (1) expiry of the component’s service life limit as defined in the AMP; (2) non-compliance with the applicable ADs and other continued-airworthiness requirement mandated by the CAA or the State of Design; (3) absence of the necessary information to determine the airworthiness status of the component or its eligibility for installation; (4) evidence of component defects or malfunctions; (5) component involvement in an incident or accident likely to affect its serviceability. (b) Unserviceable components shall be identified as one of the following: (1) unserviceable and stored in a secure location under the control of an approved maintenance organisation or independent certifying staff until a decision is made on the future status of such components; (2) unserviceable by the person or organisation that declared the component unserviceable, and its custody shall be transferred to the aircraft owner after documenting such transfer in aircraft maintenance record system referred to in point ML.A.305. (c) Components which have reached their certified life limit or contain a non-repairable defect or malfunction shall be classified as unsalvageable and shall not be permitted to re-enter the component supply system unless certified life limits have been extended or a repair solution has been approved in accordance with point ML.A.304. (d) Any person or organisation responsible pursuant to point ML.A.201 shall in the case of an unsalvageable component, as provided for in point (c), take one of the following actions: (1) retain such component in a location referred to in point (b)(1); (2) arrange for the component to be mutilated in a manner that ensures that it is beyond economic salvage or repair before relinquishing responsibility for such a component. (e) Notwithstanding point (d), a person or organisation responsible pursuant to point ML.A.201 may transfer responsibility of components classified as unsalvageable without mutilation to an organisation for training or research. Issue: 1.00 53 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements Subpart H — CERTIFICATE OF RELEASE TO SERVICE (CRS) MCAR-ML.A.801 Aircraft certificate of release to service (a) A CRS shall be issued after the required maintenance has been carried out properly on an aircraft. (b) The CRS shall be issued, alternatively by: (1) appropriate certifying staff on behalf of the approved maintenance organisation; (2) independent certifying staff; (3) the pilot- owner in compliance with point ML.A.803. (c) By derogation from point (b), in the case of unforeseen circumstances, when an aircraft is grounded at a location where no appropriately approved maintenance organisation and no appropriate certifying staff are available, the owner may authorise any person, with no less than 3 years of appropriate maintenance experience and holding the proper qualifications, to maintain the aircraft according to the standards set out in Subpart D of this Regulation and release the aircraft. The owner shall in that case: (1) obtain and keep in the aircraft records, details of all the work carried out and of the qualifications held by the person issuing the certification; (2) ensure that any such maintenance is rechecked and released in accordance with point (b) of point ML.A.801 at the earliest opportunity and within a period not exceeding 7 days or, in the case of aircraft operated under Annex VII to MCAR-Air Operations (Part- NCO) or, in the case of balloons, not engaged in commercial operations or, in the case of sailplanes not engaged in commercial operations, within a period not exceeding 30 days; (3) notify the contracted CAMO or CAO, or the competent authority in the absence of such a contract, within 7 days of the issuance of such authorisation.

(f) By derogation from point (a) and notwithstanding point (g), when the required maintenance cannot be completed, a CRS may be issued within the approved aircraft limitations. In that case, the CRS shall indicate that the maintenance could not be completed, as well as indicate any applicable airworthiness or operations limitations, as part of the information required in point (e)(4) . (g) A CRS shall not be issued in the case of any known non-compliance with the requirements of this Annex which endangers flight safety. AMC1 ML.A.801 Aircraft certificate of release to service AIRCRAFT CERTIFICATE OF RELEASE TO SERVICE (CRS) AFTER EMBODIMENT OF A STANDARD CHANGE OR A STANDARD REPAIR (SC/SR) 1. Release to service and eligible persons Only natural or legal persons entitled to release to service an aircraft after maintenance (see ML.A.801(b)) are considered as an eligible installer responsible for the embodiment of a SC/SR when in compliance with applicable requirements. Since the design of the SC/SR does not require specific approval, the natural or legal person releasing the embodiment of the change or repair takes the responsibility that the applicable certification specifications within EASA CS-STAN are fulfilled while being in compliance with this Regulation / MCAR-M Subpart F/MCAR-CAO and/or MCAR-145 and not in conflict with the TC holder’s data. This includes responsibility in respect of an adequate design, the selection/manufacturing of suitable parts and their identification, documenting the change or repair, generation or amendment of aircraft manuals and instructions as needed, embodiment of the change/repair, releasing the aircraft to service and record-keeping. Depending on its nature, for certain SCs/SRs, EASA CS-STAN might restrict the eligibility for the issuance of the release to service to certain persons (e.g. standard change/repair not suitable for release to service by the pilot-owner). 2. Parts and appliances to be installed as part of a SC/SR Issue: 1.00 55 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements The design of the parts and appliances to be used in a SC/SR is considered a part of the change/repair, and, therefore, there is no need of a specific design approval. However, it is possible that for a particular SC, these certification specifications specifically require the use of parts and appliances that meet a technical standard. In this case, when the parts and appliances are required to be authorised as an ETSO article, other articles recognised as equivalent by means of an international safety agreement or grandfathered in accordance with MCAR-21 are equally acceptable. Normally, a SC/SR shall not contain specifically designed parts that should be produced by a production organisation. However, in the case that the change or repair would contain such a part, it should be produced by an acceptable Production Organization (POA), and delivered with a CAA Form 1 or equivalent. Eligibility for installation of parts and appliances belonging to a SC/SR is subject to compliance with the MCAR-21 and this Regulation and maintenance-organisation-related provisions, and the situation varies depending on the aircraft in/on which the SC/SR is to be embodied, and who the installer is. The need for a CAA Form 1 is addressed in MCAR-21 and this Regulation, while less restrictive rules may, for instance, apply for ELA1 and ELA2 aircraft parts (e.g. MCAR-21.A.307) and sailplane parts (e.g. AMC 21.A.303 of the ‘AMC and GM to MCAR-21’). Furthermore, MCAR-M Subpart F, MCAR-CAO and MCAR-145 contain provisions (i.e. MCAR- M.A.603(c), MCAR-CAO.A.020(c) and MCAR-145.A.42(c)) that allow maintenance organisations to fabricate certain parts to be installed in/on the aircraft as part of their maintenance activities. 3. Parts’ and appliances’ identification The parts modified or installed during the embodiment of the SC/SR need to be permanently marked in accordance with MCAR-21 Subpart Q. 4. Documenting the SC/SR and declaring compliance with the certification specifications In accordance with this Regulation, MCAR-M Subpart F, MCAR-CAO or MCAR-145 (e.g. MCAR- ML.A.801(e), MCAR-M.A.612, MCAR-CAO.A.065 and MCAR-145.A.50(b)), the legal or natural person responsible for the embodiment of a change or a repair should compile details of the work accomplished. In the case of SCs/SRs, this includes, as necessary, based on the complexity, an engineering file containing drawings, a list of the parts and appliances used for the change or repair, supporting analysis and the results of tests performed or any other evidence suitable to show that the design fulfils the applicable certification specifications within EASA CS-STAN together with a statement of compliance and amendments to aircraft manuals, to instructions for continuing airworthiness and to other documents such as aircraft parts list, wiring diagrams, etc. as deemed necessary. The CAA Form 123 is prepared for the purpose of documenting the preparation and embodiment of the SC/SR. The aircraft logbook should contain an entry referring to CAA Form 123; both CAA Form 123 and the release to service required after the embodiment of the SC/SR should be signed by the same person. Issue: 1.00 56 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements CAA Form 123 and all the records listed on it should follow elementary principles of controlled documentation, e.g. contain reference number of documents, issue dates, revision numbers, name of persons preparing/releasing the document, etc. 5. Record-keeping The legal or natural person responsible (see paragraph 1. above) for the embodiment of the change/repair should keep the records generated with the SC/SR as required by this Regulation, MCAR-M Subpart F, MCAR-CAO or MCAR-145 and EASA CS-STAN. In addition, ML.A.305 requires that the aircraft owner (or CAMO or CAO, if a contract in accordance with ML.A.201 exists) keeps the status of the changes/repairs embodied in/on the aircraft in order to control the aircraft configuration and manage its continuing airworthiness. With regard to SCs/SRs, the information provided to the owner, CAMO or CAO may be listed in CAA Form 123 and should include, as required, a copy of any modified aircraft manual and/or instructions for continuing airworthiness. All this information should normally be consulted when the aircraft undergoes an AR, and, therefore, a clear system to record the embodiment of SCs/SRs, which is also easily traceable, would be of help during subsequent aircraft inspections. 6. Instructions for continuing airworthiness (ICA) As stipulated in ML.A.302, the aircraft owner, CAMO or CAO needs to assess if the changes in the ICA of the aircraft require the amendment of the AMP. 7. Embodiment of more than one SC The embodiment of two or more related SCs described in Subpart B of EASA CS-STAN is permitted as a single change (the use of one CAA Form 123 only) as long as adequate references to and records of all SCs embodied are captured. Restrictions and limitations of the two (or more) SCs would apply. It is permitted to issue a single release to service containing adequate traceability of all the SCs embodied. 8. Acceptable form to be used to record the embodiment of SCs/SRs See CAA Form 123 specified in AMC M.A.801 to MCAR-M. AMC1 ML.A.801(e) Aircraft certificate of release to service (a) The aircraft CRS should contain one of the following statements: Issue: 1.00 57 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements (1) ‘certifies that the work specified, except as otherwise specified, was carried out in accordance with MCAR-ML, and in respect to that work, the aircraft is considered ready for release to service.’; or (2) for a pilot-owner: ‘certifies that the limited pilot-owner maintenance specified, except as otherwise specified, was carried out in accordance with MCAR-ML, and in respect to that work, the aircraft is considered ready for release to service.’. (b) The CRS should relate to the task specified in the DAH’s or operator’s instruction or the AMP which itself may cross-refer to a DAH’s/operator’s instruction in a maintenance manual, service bulletin, etc. This should indicate the revision status of the maintenance instruction used. (c) The CRS should include the date when the maintenance took place relative to any life or overhaul limitation in terms of date/flying hours/cycles/ landings etc. as appropriate. (d) When extensive maintenance has been carried out, it is acceptable for the CRS to summarise the maintenance as long as there is a unique cross reference to the work pack containing full details of the maintenance carried out. Dimensional information should be retained in the work pack record. (e) The person issuing the CRS should use his or her normal signature except in the case where a computer release-to-service system is used. In this latter case, the CAA needs to be satisfied that only this particular person may electronically issue the CRS. One such method of compliance is the use of a magnetic or optical personal card in conjunction with a personal identification number (PIN) known only to the individual, which is keyed into the computer. A certification stamp is optional. (f) At the completion of all maintenance, owners, certifying staff, operators and maintenance organisations should ensure they have a clear, concise and legible record of the work performed. (g) In the case of an MCAR-ML.A.801(b)(2) CRS, the independent certifying staff should retain all records necessary to prove that all requirements have been met for the issuance of a CRS. AMC1 ML.A.801(f) Aircraft certificate of release to service Certain maintenance data issued by the DAH (e.g. AMM) requires that a maintenance task be performed in flight as a necessary condition to complete the maintenance ordered. Within the aircraft limitations, the person authorised to certify the maintenance per ML.A.801 should release the incomplete maintenance before this flight. GM1 ML.A.301(f) describes the relations with the aircraft operator, which retains the responsibility for the MCF. After performing the flight and any additional maintenance necessary to complete the maintenance ordered, a CRS should be issued in accordance with point ML.A.801. Issue: 1.00 58 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements MCAR-ML.A.802 Component certificate of release to service (a) A component CRS shall be issued after the required maintenance has been carried out properly on an aircraft component in accordance with point ML.A.502. (b) The authorised release certificate identified as CAA Form 1, as set out Appendix II of MCAR- M , constitutes the component CRS, except when such maintenance is released at aircraft level, as indicated in point ML.A.502(b). MCAR-ML.A.803 Pilot-owner authorisation (a) To qualify as a pilot-owner, the person must: (1) hold a valid pilot licence or equivalent licence issued or validated by the CAA for the aircraft type or class rating; (2) own the aircraft, either as a sole or joint owner; that owner must be, alternatively: (i) one of the natural persons on the registration form; (ii) a member of a non-profit recreational legal entity, where the legal entity is specified on the registration document as owner or operator; that member must be directly involved in the decision-making process of the legal entity and designated by that legal entity to carry out Pilot-owner maintenance. (b) For aircraft operated under Annex VII (Part-NCO) to MCAR-Air Operations or, in the case of balloons, not engaged in commercial operations or, in the case of sailplanes, not engaged in commercial operations, the pilot-owner may issue a CRS after limited Pilot-owner maintenance as provided for in Appendix II to this Regulation. (c) The CRS shall be entered in the logbooks and contain basic details of the maintenance carried out, the maintenance data used, the date on which that maintenance was completed, as well as the identity, the signature and the pilot licence (or equivalent) number of the pilot-owner issuing such a certificate. AMC1 ML.A.803 Pilot-owner authorisation (a) A pilot-owner may only issue a CRS for the maintenance he or she has performed (ref. ML.A.201(c), ML.A.801 and ML.A.803). (b) In the case of jointly-owned aircraft, the AMP should list the names of all pilot-owners that are competent and designated to perform pilot-owner maintenance (ref. ML.A.302(c)(6)). As an alternative, the AMP may contain a procedure to ensure how such a list should be managed and kept current. Issue: 1.00 59 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements (c) An equivalent valid pilot-owner licence may be any document attesting a pilot qualification recognised by the CAA. (d) Not holding a valid medical examination does not invalidate the pilot licence (or equivalent) required under ML.A.803(a)(1) for the purpose of the pilot-owner authorisation. Issue: 1.00 60 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements Subpart I — AIRWORTHINESS REVIEW CERTIFICATE (ARC) MCAR-ML.A.901 Aircraft airworthiness review To ensure the validity of the aircraft airworthiness certificate ('ARC'), an airworthiness review of the aircraft and its continuing airworthiness records shall be carried out periodically. (a) An ARC is issued in accordance with Appendix IV (CAA Form 15c) to MCAR-ML upon completion of a satisfactory airworthiness review. The ARC shall be valid for 1 year; (b) The airworthiness review and the issuance of the ARC shall be performed in accordance with point MCAR-ML.A.903, alternatively by: (1) the CAA; (2) an appropriately approved CAMO or CAO; (3) the approved maintenance organisation while performing the 100-h/annual inspection contained in the AMP; (4) for aircraft operated under Annex VII (Part-NCO) to MCAR-Air Operations or, in the case of balloons, not engaged in commercial operations or, in the case of sailplanes, not engaged in commercial operations, the independent certifying staff while performing the 100-h/annual inspection contained in the AMP, when holding: (i) a licence issued in accordance with MCAR-66 rated for the corresponding aircraft; and (ii) an authorisation issued by the CAA Whenever circumstances reveal the existence of a potential safety threat, the CAA will carry out the airworthiness review and issue the ARC itself. (c) The validity of an ARC may be extended maximum two consecutive times, for a period of one year each time, by an appropriately approved CAMO or CAO, subject to the following conditions: (1) the aircraft has been continuously managed for the previous 12 months by this CAMO or CAO; (2) the aircraft has been maintained for the previous 12 months by approved maintenance organisations; this includes pilot-owner maintenance tasks carried out and released to service either by the pilot-owner or by independent certifying staff; (3) the CAMO or CAO does not have any evidence or reason to believe that the aircraft is not airworthy. Issue: 1.00 61 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements This extension by the CAMO or CAO is possible regardless of which staff or organisation, as provided for in point (b), initially issued the ARC.

(e) When the CAA carries out the airworthiness review and issues the ARC itself, the owner shall provide the CAA with: (1) the documentation required by the CAA; (2) suitable accommodation at the appropriate location for its personnel; (3) when necessary, the support of appropriate certifying staff. GM1 ML.A.901 Aircraft airworthiness review If a CAMO/CAO holding the AR privilege is contracted by the owner, this organisation does not have the obligation to carry out the AR itself. The owner may select another CAMO or CAO to carry out the AR, or request the maintenance organisation to carry it out and issue the ARC in conjunction with the annual inspection. Please refer to GM1 ML.A.201 to identify the cases where the owner may also request an independent certifying staff (authorised by the CAA) to carry out the AR and issue the ARC in conjunction with the annual inspection. ML.A.901(b) gives a list of the different organisations or persons that are allowed to perform an AR; it does not presume that they have the obligation to accept a request to carry out an AR. MCAR-ML.A.902 Validity of the airworthiness review certificate (a) An ARC becomes invalid if, alternatively: (1) it is suspended or revoked; (2) the airworthiness certificate is suspended or revoked; (3) the aircraft is not in the aircraft register of Maldives; (4) the type certificate under which the airworthiness certificate was issued is suspended or revoked. (b) An aircraft shall not fly if the ARC is invalid or if any of the following circumstances are present: Issue: 1.00 62 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Section A – Technical Requirements (1) the continuing airworthiness of the aircraft or any component fitted to the aircraft does not meet the requirements of this Regulation; (2) the aircraft does not remain in conformity with the type design approved by the State of Design; (3) the aircraft has been operated beyond the limitations of the approved flight manual or airworthiness certificate, without appropriate action being taken; (4) the aircraft has been involved in an accident or incident that affects the airworthiness of the aircraft, without subsequent appropriate action to restore airworthiness; (5) a modification or repair to the aircraft or any component fitted to the aircraft is not in compliance with MCAR-21. (c) Upon surrender or revocation, the ARC shall be returned to the CAA. MCAR-ML.A.903 Airworthiness review process (a) To satisfy the requirement for the airworthiness review of an aircraft referred to in ML.A.901, the airworthiness review staff shall perform a documented review of the aircraft records to verify that: (1) airframe, engine and propeller flying hours and associated flight cycles have been properly recorded; (2) the flight manual is applicable to the aircraft configuration and reflects the latest revision status; (3) all the maintenance due on the aircraft according to the AMP has been carried out; (4) all known defects have been corrected or deferred in a controlled manner; (5) all applicable ADs have been applied and properly registered; (6) all modifications and repairs made to the aircraft have been registered and are in compliance with MCAR-21; (7) all service-life-limited components installed on the aircraft are properly identified, registered and have not exceeded their approved service life limit; (8) all maintenance has been certified in accordance with this Regulation; (9) if required, the current mass-and-balance statement reflects the configuration of the aircraft and is valid; Issue:

(b) The contract shall be developed taking into account the requirements of this Regulation and shall define the obligations of the signatories in relation to continuing airworthiness of the aircraft. (c) It shall contain, as a minimum the following information: (1) the aircraft registration, type and serial number; (2) the aircraft owner’s or registered lessee’s name or company details including the address; (3) details of the contracted CAMO or CAO, including the address; (4) the type of operation. (d) It shall state the following: ‘The owner entrusts the CAMO or CAO with the management of the continuing airworthiness of the aircraft, the development of a maintenance programme, and the organisation of the maintenance of the aircraft according to said maintenance programme. According to the present contract, both signatories undertake to follow the respective obligations of this contract. The owner declares, to the best of its knowledge, that all the information given to the CAMO or CAO concerning the continuing airworthiness of the aircraft is and will be accurate, and that the aircraft will not be altered without prior approval of the CAMO or CAO. In case of any non-conformity with this contract, by either of the signatories, the contract will become null. In such a case, the owner will retain full responsibility for every task linked to the continuing airworthiness of the aircraft, and the owner will inform the CAA within 2 weeks about the termination of the contract.’ (e) When an owner contracts a CAMO or CAO in accordance with point ML.A.201, the obligations of each party shall be shared as follows: (1) Obligations of the CAMO or CAO: (i) have the aircraft type included in its terms of approval; (ii) respect all the conditions listed below with regard to maintaining the continuing airworthiness of the aircraft: Issue: 1.00 74 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Appendices to the Rules (A) develop and approve the AMP for the aircraft; (B) once it has been approved, provide the owner with a copy of the AMP, as well as a copy of the justifications for any deviations from the DAH’s recommendations; (C) organise a bridging inspection using the aircraft’s prior AMP; (D) organise that all maintenance is carried out by an approved maintenance organisation or, if permitted, by independent certifying staff; (E) organise that all applicable ADs are applied; (F) organise that all defects discovered during maintenance, airworthiness reviews or reported by the owner are corrected by an approved maintenance organisation or, if permitted, by independent certifying staff; (G) coordinate scheduled maintenance, the application of ADs, the replacement of service-life-limited parts, and component inspection requirements; (H) inform the owner each time the aircraft must be brought to an approved maintenance organisation or, if permitted, to independent certifying staff; (I) manage and archive all technical records; (iii) organise the approval of any modification to the aircraft in accordance with MCAR- 21 before this modification is embodied; (iv) organise the approval of any repair to the aircraft in accordance with MCAR-21 before this repair is carried out; (v) inform the CAA whenever the aircraft is not presented by the owner for maintenance as requested by the contracted CAMO or CAO; (vi) inform the CAA whenever the present contract has not been respected; (vii) ensure that the airworthiness review of the aircraft is carried out, when necessary, and ensure that the ARC is issued; (viii) send within 10 days a copy of any ARC issued or extended to the CAA; (ix) carry out all occurrence reporting mandated by applicable regulations; (x) inform the CAA whenever the present contract is denounced by either party. (2) Obligations of the owner: Issue: 1.00 75 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Appendices to the Rules (i) have a general understanding of the AMP; (ii) have a general understanding of this Regulation; (iii) present the aircraft for maintenance as directed by the contracted CAMO or CAO; (iv) not modify the aircraft without first consulting the contracted CAMO or CAO; (v) inform the contracted CAMO or CAO of all maintenance exceptionally carried out without the knowledge and control of the contracted CAMO or CAO; (vi) report to the contracted CAMO or CAO through the logbook all defects found during operations; (vii) inform the CAA whenever the present contract is denounced by either party; (viii) inform the CAA and the contracted CAMO or CAO whenever the aircraft is sold; (ix) carry out all occurrence reporting mandated by applicable regulations; (x) inform on a regular basis the contracted CAMO or CAO about the aircraft flying- hours and any other utilisation data, as agreed with the contracted CAMO or CAO; (xi) enter the CRS in the logbooks, as mentioned in point ML.A.803(c), when performing pilot-owner maintenance; (xii) inform the contracted CAMO or CAO no later than 30 days after completion of any Pilot-owner maintenance task. Issue: 1.00 76 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Appendices to the Rules Appendix II Limited Pilot-Owner Maintenance In addition to the requirements laid down in this Regulation, the pilot-owner shall comply with the following basic principles before it carries out any maintenance task: (a) Competence and responsibility (1) The Pilot-owner shall always be responsible for any maintenance that he performs. (2) The pilot-owner shall hold satisfactory level of competence to perform the task. It is the responsibility of a pilot-owner to familiarise himself with the standard maintenance practices for his aircraft and with the AMP. (b) Tasks The Pilot-owner may carry out simple visual inspections or operations to check the airframe, engines, systems and components for general condition, obvious damage and normal operation. A maintenance task shall not be released by the pilot-owner if any of the following conditions occurs: (1) is a critical maintenance task; (2) it requires the removal of major components or a major assembly; (3) it is carried out in compliance with an AD or an airworthiness limitation item (ALI) unless specifically allowed in the AD or the ALI; (4) it requires the use of special tools or calibrated tools (except for torque wrench and crimping tool); (5) it requires the use of test equipment or special testing (e.g. non-destructive testing (NDT), system tests or operational checks for avionics equipment); (6) it is composed of any unscheduled special inspections (e.g. heavy-landing check); (7) it affects systems essential for the instrumental flight rules (IFR) operations; (8) it is a complex maintenance task in accordance with Appendix III, or it is a component maintenance task in accordance with point (a) or (b) of point ML.A.502; (9) it is part of the 100-h/annual check (for those cases the maintenance task is combined with the airworthiness review performed by maintenance organisations or independent certifying staff). The criteria referred to in points (1) to (9) cannot be overridden by less restrictive Issue: 1.00 77 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Appendices to the Rules instructions issued in accordance with the AMP referred to in point ML.A.302. Any task described in the aircraft flight manual (or other operational manuals), for example preparing the aircraft for flight (assembling the sailplane wings, or performing a preflight inspection, or assembling a basket, burner, fuel cylinders and an envelope combination for a balloon, etc.), is not considered a maintenance task and, therefore, does not require a CRS. Nevertheless, the person assembling those parts is responsible for ensuring that those parts are eligible for installation and in a serviceable condition. (c) Performance and records of the pilot-owner maintenance tasks The maintenance data, as specified in point ML.A.401, must always be available during the conduct of pilot-owner maintenance and must be complied with. Details of the data referred to in the conduct of pilot-owner maintenance must be included in the CRS in accordance with point (d) of point ML.A.803. The pilot-owner must inform the contracted CAMO or CAO (if such contract exists) about the completion of the pilot-owner maintenance tasks no later than 30 days after completion of these tasks in accordance with point (a) of point ML.A.305. Issue: 1.00 78 30 March 2022 Maldivian Civil Aviation Regulations MCAR-ML Continuing Airworthiness for Light Aircraft Maldives Civil Aviation Authority Appendices to the Rules AMC 1 to Appendix II to MCAR-ML — Limited pilot-owner maintenance (a) The lists below specify items that may be expected to be completed by an owner who holds a current and valid pilot licence for the aircraft type involved and who meets the competence and responsibility requirements of Appendix II to this Regulation. (b) The list of tasks may not address in a detailed manner the specific needs of the various aircraft categories. In addition, the development of technology and the nature of the operations undertaken by these categories of aircraft cannot be always adequately considered. (c) Any other task meeting the requirements of Appendix II to this Regulation may also be performed by the pilot-owner. (d) Therefore, the following lists are considered to be the representative scope of limited Pilot- owner maintenance referred to in ML.A.803 and Appendix II to this Regulation: (1) Part A applies to aeroplanes; (2) Part B applies to rotorcraft; (3) Part C applies to sailplanes and powered sailplanes; and (4) Part D applies to balloons and airships. (e) Inspection tasks/checks of any periodicity included in an approved maintenance programme can be carried out providing that the specified tasks are compliant with the basic principles of Appendix II to this Regulation. The content of periodic inspections/checks as well as their periodicity is not regulated or standardised in an aviation specification. It is the decision of the DAH to recommend a schedule for each specific type of inspection/check. For an inspection/check with the same periodicity for different aircraft, the content may differ and in some cases, may be critically safety-related and need the use of special tools or knowledge and thus, not qualify for pilot-owner maintenance. Therefore, the maintenance carried out by the pilot-owner should not be generalised to specific inspections such as of a 50-h, 100-h or 6-month periodicity. The Inspections to be carried out are limited to those areas and tasks listed in this AMC to Appendix II; this allows flexibility in the development of the maintenance programme and does not limit the inspection to certain specific periodic inspections. A 50-h /6 Month periodic inspection for a fixed-wing aeroplane as well as the 1-year inspection for a glider may normally be eligible for pilot-owner maintenance.
