M.A.901 Aircraft airworthiness review Regulation (EU) 2022/1360 To ensure the validity of the aircraft airworthiness certificate, an airworthiness review of the aircraft and its continuing airworthiness records shall be carried out periodically. (a) An airworthiness review certificate is issued in accordance with Appendix III ([EASA Form 15a](#_DxCrossRefBm1518545212) or [15b](#_DxCrossRefBm1518545213)) to this Annex upon completion of a satisfactory airworthiness review. The airworthiness review certificate shall be valid for 1 year; (b) An aircraft in a controlled environment is an aircraft which, during the preceding 12 months: 1. has had its airworthiness continuously managed by a unique CAMO or CAO; 2. has been maintained by a maintenance organisation approved in accordance with Subpart F of this Annex, Annex II (Part-145) or Annex Vd (Part-CAO), including the cases when maintenance tasks referred to in point (b) of point [M.A.803](#_DxCrossRefBm1518544871) are carried out and released to service in accordance with point (b)(1) or (b)(2) of point [M.A.801](#_DxCrossRefBm1518544907) of this Annex. (c) For all aircraft used by air carriers licensed in accordance with Regulation (EC) No 1008/2008, and for aircraft above 2 730 kg MTOM that are in a controlled environment, the organisation referred to in point (b)(1) managing the continuing airworthiness of the aircraft may in accordance with [CAMO.A.125(e)](#_DxCrossRefBm1518545216) of Annex Vc or point [M.A.711(b)](#_DxCrossRefBm1518545123) of this Annex or point [CAO.A.095(c)(1)](#_DxCrossRefBm1518545215) of Annex Vd, as applicable, and subject to compliance with point (j): 1. issue an airworthiness review certificate in accordance with point [M.A.901](#_DxCrossRefBm1518544877); 2. extend at most twice the validity of the airworthiness review certificate it has issued, for a period of 1 year each time, where the aircraft concerned has remained within a controlled environment. (d) The airworthiness review certificate shall be issued by the competent authority upon a satisfactory assessment based on a recommendation made by a CAMO or CAO, sent together with the application from the owner or operator for all aircraft used by air carriers licensed in accordance with Regulation (EC) No 1008/2008, and for aircraft above 2 730 kg MTOM that complies with the following alternative conditions: 1. they are not in a controlled environment; 2. their continuing airworthiness is managed by an organisation that does not hold the privilege to carry out airworthiness reviews. The recommendation referred to in the first subparagraph shall be based on an airworthiness review carried out in accordance with point [M.A.901](#_DxCrossRefBm1518544877). (e) For aircraft of 2 730 kg MTOM and below not used by air carriers licensed in accordance with Regulation (EC) No 1008/2008, any CAMO or CAO chosen by the owner or operator may in accordance with CAMO.A.125(e) of Annex Vc or point M.A.711(b) of this Annex or CAO.A.095(c) of Annex Vd, as applicable, and subject to compliance with point (j): 1. issue the airworthiness review certificate in accordance with point [M.A.901](#_DxCrossRefBm1518544877); 2. extend at most twice the validity of the airworthiness review certificate it has issued, for a period of 1 year each time, where the aircraft has remained within a controlled environment under its management. (f) By derogation from points (c)(2) and (e)(2) of point [M.A.901](#_DxCrossRefBm1518544877), for aircraft that are in a controlled environment, the organisation referred to in point (b)(1) managing the continuing airworthiness of the aircraft, may, subject to compliance with point (j), extend at most twice the validity of an airworthiness review certificate that the competent authority or another CAMO or CAO has issued, for a period of 1 year each time. (g) Whenever circumstances reveal the existence of a potential risk to aviation safety, the competent authority shall carry out the airworthiness review and issue the airworthiness review certificate itself. (h) Without prejudice to point (g), the competent authority may carry out the airworthiness review and issue the airworthiness review certificate itself in the following cases: 1. when the continuing airworthiness of the aircraft is managed by a CAMO or CAO which has its principal place of business located in a third country; 2. for any other aircraft of 2 730 kg MTOM and below, if the owner so requests. (i) Where the competent authority issues the airworthiness review certificate itself in accordance with points (g) or (h) or after assessing the recommendation in accordance with point [M.B.901](#_DxCrossRefBm1518545214), the owner or operator of the aircraft shall, where necessary for those purposes, provide the competent authority with: 1. any documentation required by the competent authority; 2. suitable accommodation at the appropriate location for its personnel; 3. the support of the certifying staff (j) An airworthiness review certificate shall not be issued, nor extended if there is evidence or indications that the aircraft is not airworthy.
