Full official abstract

This amendment adopts a new airworthiness directive (AD) that applies to certain Pilatus Britten-Norman Ltd. (PBN) BN-2, BN-2A, BN- 2B, and BN-2A MK. 111 series airplanes that are equipped with a PBN Modification NB/M/256, 50A generator system. This AD requires inspecting the airplanes that are equipped with a 50A generator system for a 70A generator. If a 70A generator is installed, this AD requires replacing the 70A generator with a 50A generator, or (for the BN-2, BN-2A, and BN-2B series only) upgrading the airplane generator system to a 70A system to match the 70A generator. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. The actions specified by this AD are intended to detect and correct damage to the components of the electrical system, which could result in electrical system failure during critical phases of flight.
