FAQ n.19400

What is an Alternative Method of Compliance (AMOC) to an Airworthiness Directive (AD)?

Answer

An Alternative Method of Compliance (AMOC) is an EASA approved deviation to an AD. 
It is a different way, other than the one specified in an AD, to address an unsafe condition on products, parts and appliances. An AMOC must provide a level of safety equivalent to the level of safety to be restored by  compliance with the original AD.
AMOCs may be issued in respect of, but are not necessarily limited to, the following:

  • Alternative modifications,
  • Alternative inspection procedures,
  • Alternative maintenance intervals and/or procedures,
  • Specific operating procedures or limitations, etc.
