Airworthiness Directive · Amendment 39-11081 · Pilatus Aircraft Ltd. Models PC-12 and PC-12/45 Airplanes
Pilatus Aircraft Ltd. Models PC-12 and PC-12/45 Airplanes
Models PC-12 and PC-12/45 airplanes, manufacturer serial numbers (MSN) 101 through MSN 180, 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 a support bracket and a cut-out relay for the second generator control unit. This AD also requires making all the wiring additions and adjustments necessary for the above-referenced installations. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. The actions specified in this AD are intended to prevent damage to electrical components because incorrectly connected cables or broken or damaged wires cause excessive voltages to the second generator, which could result in loss of electrical power during any phase of flight.
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.
