7 Continuing Airworthiness Requirements GAR Part 39 Page 1 Subpart A General 39.1 Purpose (a) This Part details requirements governing aircraft registered in Guernsey and issued with an airworthiness certificate under Part 21 Subpart E and any aeronautical product associated with those aircraft. The requirements of this GAR Part cover continuing airworthiness management and the grant and renewal of continuing airworthiness inspection programmes. The owner or charterer by demise of an aircraft registered in Guernsey shall have arrangements for continuing airworthiness management to the requirements of Subpart B and, if applicable, Subpart G of this GAR Part. (b) For continuing airworthiness management of Guernsey registered aircraft, these are the options under this GAR Part: (1) acceptance under GAR by the Director of a Technical Co-ordinator appointed by the owner or charterer by demise of the aircraft; (2) Subpart G option 1: validation of an organisation approved to undertake continuing airworthiness management of aircraft to the requirements of EASA Part M Subpart G as amended (EASA CAMO); (3) Subpart G option 2: validation of an organisation approved to undertake continuing airworthiness management of aircraft to the requirements equivalent to those of EASA Part M Subpart G as amended, subject to acceptance by the Director of Civil Aviation (EASA equivalent CAMO); (4) Subpart G Option 3: the approval of an organisation that does not hold an approval identified in paragraph 39.1(b)(1) or 39.1(b)(2). (c) These Requirements are not in themselves Law. Failure to comply may not constitute an offence. However, the Requirements repeat or reproduce many of the provisions of the Air Navigation (Bailiwick of Guernsey) Law 2012, as amended ( the Law ), including the Rules of the Air set out in Schedule 4 to the Law. Therefore, failure to comply with these Requirements may: (1) constitute a breach of the Law; and (2) result in proceedings for breaches of the Law; or (3) result in the refusal of an application for renewal of a certificate; or (4) result in action to suspend or revoke a certificate.
8 Continuing Airworthiness Requirements GAR Part 39 Page 2 (d) The Law details the legal obligations governing the continuing airworthiness of aircraft on Guernsey s register. The Law specifies these obligations in rather general terms, therefore there is a provision in Section 135 (Publication of Requirements) to the Law which requires the Director to publish Requirements to augment, amplify and detail more precisely the manner in which these obligations shall be met. The Requirements are the means by which the operator, the Technical Co-ordinator, the Continuing Airworthiness Management Organisation or maintenance organisation will be able to satisfy the Director as to the fulfilment of the obligations in respect of continuing airworthiness and the entitlement of the holder to hold and exercise the privileges of a certificate or approval. (e) The issue of a certificate or approval indicates only compliance with the relevant requirements. The possession of a certificate or approval does not relieve the operator, owner of an aircraft or the pilot-in-command from the responsibility for compliance with the Law and any other legislation in force. Neither does it relieve them of their responsibility for the safe conduct of any particular flight, as the ultimate responsibility for the safety of flight operations always rests with the operator and the pilot-in-command Definitions Definitions, in the context of this Part of the GARs shall have the meanings listed in GAR Part 1 (Definitions, Abbreviations and Units of Measurement).
9 Continuing Airworthiness Requirements GAR Part 39 Page 3 Subpart B Continuing Airworthiness Management Management personnel (a) Section 7(1)(a) of the Air Navigation (Bailiwick of Guernsey) Law, 2012 states that an aircraft registered in Guernsey in respect of which a certificate of airworthiness is in force shall not fly unless: (1) the aircraft's continuing airworthiness, (including that of its engines, equipment and radio station), is managed by a person or organisation approved by the Director in accordance with a maintenance programme under a maintenance control manual or equivalent document approved by the Director in relation to that aircraft, (2) for aircraft having an MTOM authorised exceeding 2,700kg, a Technical Coordinator, acceptable to the Director, shall be appointed who shall ensure that appropriate arrangements for continuing airworthiness management required by this GAR Part are in place. (b) As an alternative to GAR 39.51(a)(2), applicants may choose to use the services of a continuing airworthiness management organisation to satisfy the requirements in 39.51(a), as follows: (1) Option 1 Subpart G: an organisation approved to undertake continuing airworthiness management of aircraft to the requirements of EASA Part M Subpart G as amended; (2) Option 2 Subpart G: an organisation approved to undertake continuing airworthiness management of aircraft to the requirements equivalent to those of EASA Part M Subpart G as amended, subject to acceptance by the Director of Civil Aviation; (3) Option 3 Subpart G: an organisation that does not hold an approval identified in paragraph 39.51(b)(1) or 39.51(b)(2) Technical Co-ordinator (a) The owner or charterer by demise of an aircraft above 2,700 kg MTOM that does not choose to have the continuing airworthiness of its aircraft managed by a Continuing Airworthiness Management Organisation as per GAR 39.51(b) shall nominate a Technical Co-ordinator for acceptance by the Director. The Director shall evaluate the nominee for his or her capability to perform the functions as per GAR and GAR and confirm acceptance by means of a Technical Co-ordinator acceptance. (b) Acceptance of a Technical Co-ordinator is specific to a specific owner or charterer by demise and a specific aircraft as identified by aircraft type and serial number.
