AD 2016-12-01 81 FR 37494

We are adopting a new airworthiness directive (AD) for PILATUS AIRCRAFT LTD. Models PC-12, PC-12/45, PC-12/47, and PC-12/47E airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as incorrect installation instructions of the torlon plates in the airplane maintenance manual resulting in the incorrect installation of the torlon plates in the forward wing-to-fuselage attachment. We are issuing this AD to require actions to address the unsafe condition on these products.
