Airworthiness Directive · Amendment 39-11433 · 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 number (MSN) 101 through MSN 300, 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 modifying the flap inboard attachment fittings through the installation of a reinforcement angle bracket on the inside of the center web of both flap inner attachment fittings. 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 the potential of the inboard flap attachment fittings buckling while operating at full flaps with full power into a head-on wind gust, which could result in loss of control of 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.
