EASA Airworthiness Review Certificate | AESA-Agencia Estatal de Seguridad Aérea

A CAMO may extend the ARC of an aircraft, during maintenance, with a partial CRS prior to the MCF (Maintenance Check Flight).

M.A.901(c)(2) and (f) allow the CAMO managing the aircraft to extend the ARC subject to the conditions of M.A.901(b), for controlled environment, and M.A.901(j), regarding the prohibition to extend the ARC if there is evidence that the aircraft is not airworthy.

The fact that the ARC expires during base maintenance and was subsequently extended after partial CRS prior to the MCF would not automatically imply that the aircraft was not in a controlled environment.
