EASA does not approve AD compliance time extension requests for individual cases.
For an aircraft registered in an EASA Member State, the National Aviation Authority of the Member State can grant individual (temporary) exemptions on AD compliance time in the event of unforeseen urgent operational circumstances or operational needs of a limited duration, in accordance with Basic Regulation, Article 71.
For any other aircraft, the State of Registry authority should be contacted.
An extension of the AD compliance time for an individual product without ‘compensating factors’ that would provide for an equivalent level of safety is not to be considered as Alternative Method of Compliance (AMOC) to an AD. See also AMOC FAQ.
