ED Decision 2020/002/R
The responsibilities associated with maintenance programmes developed in accordance with ML.A.302 are the following:
ED Decision 2020/002/R
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 developing the AMP | Contracted CAMO or CAO | Owner (if allowed under ML.A.201(f)) |
| Approval/declaration of the maintenance programme | Approved by the CAMO or CAO, or none required in case of compliance with ML.A.302(e) | Declaration by the owner or none required in case of compliance with ML.A.302(e) |
| Basis for the maintenance programme | MIP (not applicable to rotorcraft and airships) or ICA issued by the DAH | |
| Deviations from the DAH’s ICA | Deviations from the DAH’s instructions are justified. The CAMO/CAO keeps a record of the justifications and provides a copy of them to the owner. | Deviations do not need to be justified. |
| 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. | |
ED Decision 2020/002/R
When evaluating an alternative to a maintenance task issued or recommended by the DAH, such 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 airworthiness of the aircraft? | HIGHER RISK: owner |
| LOWER RISK: CAMO/CAO | |
| Who maintains the aircraft? | HIGHER RISK: pilot-owner |
| MEDIUM RISK: independent certifying staff | |
| LOWER RISK: maintenance organisation | |
| Time in service (flight hours, years) | HIGHER RISK: very high number of hours or years |
| MEDIUM RISK: medium number of hours or years | |
| LOWER RISK: low number of hours or years | |
| Aircraft utilisation | HIGHER RISK: less than 50 h per year |
| MEDIUM RISK: around 200 h per year | |
| LOWER RISK: more than 400 h per year | |
| ACAM findings | HIGHER RISK: numerous findings in ACAM or ramp inspections |
| MEDIUM RISK: few findings in ACAM inspections | |
| LOWER RISK: rare findings in ACAM inspections | |
| System redundancy (for components such as engine/propeller) | HIGHER RISK: single-engined aircraft |
| LOWER RISK: multi-engined aircraft | |
| Supplementary maintenance measures | HIGHER RISK: no supplementary measures |
| LOWER RISK: supplementary measures (such as oil analysis, engine data monitoring, boroscope inspections, corrosion inspections, etc.) | |
| Risk factor of the component failure | HIGHER RISK: engine failure on a helicopter |
| MEDIUM RISK: engine failure on an aeroplane | |
| LOWER RISK: sailplane, or powered sailplane |
The above information may be useful for CAMOs and CAOs when developing and approving maintenance programmes, and for the AR staff performing ARs and reviewing the effectiveness of the declared maintenance programme. 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 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.
ED Decision 2020/002/R
ANNUAL REVIEW OF THE AMP
ED Decision 2020/002/R
‘DAH’ refers to the holder of a type certificate (TC), restricted type certificate, supplemental type certificate (STC), 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 competent authority. Justification of these deviations are to be kept by the CAMO or CAO.
ED Decision 2020/002/R
‘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 alternative | MIP task | Alternative acceptable Yes/No |
|---|---|---|---|
| Inspection XX 6 months interval | Inspection XX 12 months interval | Inspection XX 12 months interval | Yes |
| Inspection XX 12 months interval | Inspection XX 24 months interval | Inspection XX 12 months interval | No |
| Inspection XX 12 months interval | Inspection XX 24 months interval | Inspection XX 12 months interval | No (24 months to be kept) |
| Functional test system XX | Operational test system XX (same interval) or general visual inspection system XX (same interval) | Functional test system XX (same interval) | No* |
| Operational test system XX | Functional test system XX (same interval) |
interval)|Yes*|
| Inspection XX 24 months interval | Inspection XX 36 months | None relevant | Yes |
| Functional test | General visual inspection | None relevant | Yes |
*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.
ED Decision 2020/002/R
MANDATORY CONTINUING AIRWORTHINESS INFORMATION OTHER THAN ADS
‘Mandatory continuing airworthiness information’ other than ADs may be different from one aircraft to an other, 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:
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.
ED Decision 2020/002/R
This AMC contains an acceptable MIP for aeroplanes of 2 730 kg maximum take-off mass (MTOM) and below, and for ELA2 aircraft other than airships, grouped in the following categories:
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.
Betrifft Ballone nicht, gelegentlich einfügen.
Betrifft Ballone nicht - gelegentlich einfügen.
To be performed at every 100-h/annual 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 carried out wherever a check for improper installation/operation is performed.

ED Decision 2020/002/R
OPERATIONAL TEST AND FUNCTIONAL TEST
An operational test (or operational check) is a task used to determine that an item is operating normally. It does not require quantitative tolerances.
A functional test (or functional check) is a quantitative check to determine if one or more functions of an item performs within the limits specified in the appropriate maintenance data. The measured parameter should be recorded.
ED Decision 2020/002/R
OPERATIONAL TEST OF TRANSPONDER
A transponder test that is carried out in accordance with EASA SIB 2011-15 or US Title 14 CFR Part 43 Appendix F is considered to include the MIP task described in ML.A.302(d)(2)(d).
