FAQ n.19212

What are alternative means of compliance (AltMoC)?

Answer

Implementing Rules of the EASA Basic Regulation define AltMoC as follows:

‘Alternative means of compliance’ mean those means that propose an alternative to an existing Acceptable Means of Compliance or those that propose new means to establish compliance with Regulation (EU) 2018/1139 (Regulation (EC) No 216/2008 for CH,IS, LI and NO) and  its Implementing Rules for which no associated AMC have been adopted by the Agency´.

Complementing the legal provisions, the Agency has developed further criteria that may be used to characterise an AltMoC:

  • It is technically different in character to the published EASA AMC;
  • A form included in EASA AMC is changed in layout or by adding/deleting fields;
  • A change of numbering, e.g. table of contents of the Operations Manual, is not per se an AltMoC, only if the order or numbering of whole chapters is changed (e.g. Chapter 7 becomes Chapter 8).

Editorial changes to an EASA AMC are not considered to constitute an AltMoC.

Please note that the above can only be a general guideline. Organisations and competent authorities may need to evaluate each case to establish if a means of compliance is an AltMoC.
