M.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 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.
