Full official abstract

This amendment adopts a new airworthiness directive (AD) that applies to certain Pilatus Aircraft Ltd. (Pilatus) Model PC-12 airplanes. This AD requires replacing and re-routing the power return cables on the starter generator and generator 2, inserting a temporary revision to the pilot operating handbook (POH), and installing a placard near the standby magnetic compass. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. The actions specified by this AD are intended to prevent directional deviation on the standby magnetic compass caused by an overload of electrical current in the airplane structure, which could result in flight-path deviation during critical phases of flight in icing conditions and instrument meteorologic conditions (IMC).
