Acceptable Means of Compliance (AMC) and Guidance Material (GM)


Acceptable means of compliance (AMC) means non-binding standards adopted by the Agency (European Aviation Safety Agency (EASA)) to illustrate means to establish compliance with Regulation (EC) No 216/2008 and its Implementing Rules (IR-OPS). (Annex I to Regulation (EC) No 965/2012 (IR-OPS)).

Guidance Material (GM) may be provided by the Agency to assist the user in complying with an Implementing Rule (IR), where this material does not form part of the IR or associated AMC.


The term Acceptable Means of Compliance (AMC) (as referred to in Articles 18 and 19 of the ‘Basic Regulation’ and its Implementing Rules) is primarily used to qualify technical interpretative material to be used in the certification process. In this respect, the AMC serve as means by which the certification requirements contained in the ‘Basic Regulation, its Implementing Rules and, more specifically, in their annexes (also referred to as "Parts"), can be met by those subject to the Regulation.

For example, IR-OPS Setion ARO.GEN.120 Means of compliance sub-paragraph (a) states that:

The Agency (EASA) shall develop acceptable means of compliance (AMC) that may be used to establish compliance with Regulation (EC) No 216/2008 (the Basic Regulation) and its Implementing Rules. When the AMC are complied with, the related requirements of the Implementing Rules are met.

AMC material is not binding on those applying for regulatory approval, who may decide to show compliance with the applicable certification requirements using other means (Alternative Means of Compliance). Competent NAAs may also produce their own acceptable means of compliance, based or not on those issued by EASA. Just as with AMC issued by EASA, such national means of compliance cannot bind the applicants either; the applicant can always choose to comply by other means; however, such alternative means of compliance must be approved by the competent authority.
