Airworthiness Directive · Amendment 39-10475 · Pilatus Aircraft Ltd. Models PC-12 and PC-12/45 Airplanes
Pilatus Aircraft Ltd. Models PC-12 and PC-12/45 Airplanes
Model PC-12 and PC-12/45 airplanes, serial numbers MSN 001 through MSN 168, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that applies to certain Pilatus Aircraft Ltd. (Pilatus) Models PC-12 and PC- 12/45 airplanes. This AD requires installing aluminum bonding bushings over certain screws in certain fuel tank underwing access panels. Several reports from the field revealing fuel tank access panels insufficiently electrically bonded to the airframe prompted this action. The actions specified by this AD are intended to prevent electrical arcing in the fuel tanks and detonation of the fuel-air mixture, which can be created by poor electrical bonding of fuel tank underwing access panels, and could result in a fire on the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
