The document the work is organised around
The work card for MSN-EXAMPLE-014 gives an interval. That interval is an entry in the aircraft maintenance programme. M.A.302 is the rule for the programme under Part-M: content, approval, the derogation, the reliability programme, and the review.
The overview quotes who is responsible, and which aircraft are in Part-ML. This page does not restate either.
M.A.302
(a)Maintenance of each aircraft shall be organised in accordance with an AMP.
(b)The AMP and any subsequent amendments thereto shall be approved by the competent authority.
(c)When the continuing airworthiness of aircraft is managed by a CAMO or CAO, or when there is a limited contract between the owner and a CAMO or CAO concluded in accordance with point M.A.201(i)(3), the AMP and its amendments may be approved through an indirect approval procedure.
In that case, the indirect approval procedure shall be established by the CAMO or CAO concerned as part of the continuing airworthiness management exposition (‘CAME’) referred to in point CAMO.A.300 of Annex Vc or point M.A.704 of this Annex, or as part of the combined airworthiness exposition (‘CAE’) referred to in point CAO.A.025 of Annex Vd and shall be approved by the competent authority responsible for that CAMO or CAO.
The indirect approval procedure shall only be used when the CAMO or CAO concerned is under the oversight of the Member State of registry of aircraft, unless a written contract has been concluded in accordance with point 3 of point M.1 transferring responsibility for the approval of the aircraft maintenance programme to the competent authority responsible for the CAMO or CAO.
(d)The AMP shall demonstrate compliance with:
(1)the instructions issued by the competent authority;
(2)the instructions for continuing airworthiness:
(i)issued by the holders of the type certificate, restricted type certificate, supplemental type certificate, major repair design approval, ETSO authorisation or the declarant of a declaration of design compliance or the holder of any other relevant approval issued under Annex I (Part 21) or, as applicable, Annex Ib (Part 21 Light), to Regulation (EU) No 748/2012;
(ii)included in the certification specifications referred to in points 21.A.90B or 21.A.431B of Annex I (Part 21) to Regulation (EU) No 748/2012, if applicable;
(iii)included in the certification specifications referred to in points 21L.A.62, 21L.A.102, 21L.A.202 or 21L.A.222 of Annex Ib (Part 21 Light) to Regulation (EU) No 748/2012, if applicable;
(3)the applicable provisions of Annex I (Part-26) to Regulation (EU) 2015/640;
(e)By derogation to point (d), the owner or the organisation managing the continuing airworthiness of the aircraft may deviate from the instruction referred to in point (d)(2) and propose escalated intervals in the AMP, based on data obtained from sufficient reviews carried out in accordance with point (h). Indirect approval is not permitted for the escalation of safety-related tasks. The owner or the organisation managing the continuing airworthiness of the aircraft may also propose additional instructions in the AMP.
(f)The AMP shall contain details of all maintenance to be carried out, including frequency and any specific tasks linked to the type and specificity of operations.
(g)For complex motor-powered aircraft, when the AMP is based on maintenance steering group logic or on condition monitoring, the AMP shall include a reliability programme.
(h)The AMP shall be subject to periodic reviews and be amended accordingly when necessary. Those reviews shall ensure that the AMP continues to be up to date and valid in light of the operating experience and instructions from the competent authority, while taking into account new or modified maintenance instructions issued by the type-certificate and supplemental type-certificate holders, declarant of a declaration of design compliance and any other organisation that publishes such data in accordance with Annex I (Part 21) or, as applicable, Annex Ib (Part 21 Light) to Regulation (EU) No 748/2012.
Quoted word for word from Regulation (EU) No 1321/2014, Easy Access Rules for Continuing Airworthiness, 2 Sep 2025 revision.
Points (d) and (f) are the content. A working list of when each interval next falls due is a separate thing from the approved programme; Aviation Tracking Spreadsheet: Free Template and Registers covers that list.
Point (e)
Quoted above in full. The reliability guide does not restate it.
Approval
Point (b) and point (c) are the approval routes. Read (c) to the end, including point M.A.704 and point 3 of point M.1. The CAMO and CAO guide quotes the exposition. It does not restate this approval rule.
Where the overview keeps an aircraft in Part-M rather than Part-ML, that listing condition is quoted there. It is not restated here.
Review and the reliability programme
The next guide quotes (g) and (h) again, and quotes the AMC. It does not restate point (e).
Part-ML
Which aircraft are in Part-ML is quoted in the overview. The list is not repeated here. For an aircraft that is in Part-ML, the programme rule is ML.A.302.
[…]
(b)The AMP and any subsequent amendments thereto shall be, alternatively:
(1)declared by the owner in accordance with point (c)(7) of point ML.A.302, 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.
[…]
(7)when declared by the owner, shall contain a signed statement by which the owner declares that this is the AMP for the particular aircraft registration and that he is fully responsible for its content and, in particular, for any deviations from the DAH’s recommendations;
[…]
(9)shall be reviewed at least annually in order to assess its effectiveness, and this review shall be performed, alternatively:
(a)in conjunction with the airworthiness review of the aircraft by the person who performs such an airworthiness review;
(b)by the CAMO or CAO managing the continuing airworthiness of the aircraft in those cases where the review of the AMP is not performed in conjunction with an airworthiness review.
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 competent authority of the Member State of registry if he does not agree with the measures amending the AMP taken by the owner, CAMO or CAO. The competent authority shall decide which amendments to the AMP are necessary, raising the corresponding findings and, if necessary, reacting in accordance with point ML.B.304.
[…]
(e)By derogation from points (b) and (c), a declaration by the owner or an approval by a CAMO or CAO is not required, and an AMP document is not required to be produced when the following conditions are met:
(1)all the ICA issued by the DAH are being followed without any deviations;
(2)all maintenance recommendations, such as TBO intervals, issued through service bulletins, service letters, and other non-mandatory service information, are being followed without any deviations;
(3)there are no additional maintenance tasks to be performed resulting from any of the following:
(a)specific installed equipment and modifications of the aircraft;
(b)repairs carried out in the aircraft;
(c)life-limited components and flight-safety-critical components;
(d)special operational approvals;
(e)use of the aircraft and operational environment.
(4)Pilot-owners are authorised to perform Pilot-owner maintenance.
This derogation is not applicable if the pilot-owner or, in case of jointly-owned aircraft, any of the pilot-owners is not authorised to perform Pilot-owner maintenance because this has to be specified in the declared or approved AMP.
(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;
(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.
Quoted word for word from Regulation (EU) No 1321/2014, Easy Access Rules for Continuing Airworthiness, 2 Sep 2025 revision.
Read (e) and (f) before treating (b) as the only route.
