• Regulation (EU) No. 1321/2014 determines the rules for the continuing airworthiness and maintenance of aircraft subject to EASA regulation. Part M Subpart G of this regulation concerns the management of continuing airworthiness of EASA aircraft.

    Organisations approved to Part M Subpart G can additionally be approved to make recommendations to a competent authority that an Airworthiness Review Certificate (EASA Form 15a) may be issued or in certain cases issue and extend an Airworthiness Review Certificate (EASA Form 15b) under the terms of their approval.

    Part M Subpart G organisations holding the Airworthiness Review privilege may also be approved to issue Permits to Fly in accordance with Part 21 Subpart P when the aircraft is in conformity with the approved Flight Conditions. Please note: this privilege does not allow the Part M Subpart G organisation to approve the Flight Conditions.

    There are two elements of a Part M Subpart G approval:

    1. Those associated with the aircraft registrations listed on the organisation's Air Operators Certificate (AOC) and covering the continuing airworthiness management of commercial air transport (CAT) aircraft.
    2. Those associated with the continuing airworthiness management of aircraft not involved in commercial air transport (non-CAT), as listed on their Part M Subpart G approval certificate.


    Organisations must ensure that both aspects of their approval are changed (the AOC and Part MG).

    Who can apply?

    An organisation with their principal place of business located in the UK that wishes to carry out the management of continuing airworthiness management of EASA aircraft.

    Organisations with their principal place of business located outside the UK, including the Channel Islands, should apply directly to EASA.

    Organisations needing to change a Registered Company or Limited Liability Partnership (LLP) Number will require a new initial approval as it cannot be classed as a change to an existing approval. See CAP 562, Leaflet C-30 for further information.

    If adding an aircraft which falls within a generic aircraft group that you already hold on your approval certificate (e.g. Piston engine aeroplanes – metal structure not exceeding 5700 kg) then you should email an exposition amendment to apply@caa.co.uk or attach/upload the draft exposition to the online application form (where applicable). Please do not send to your surveyor directly as it will delay your application processing.
