Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Pilatus Aircraft Ltd. (Pilatus) Models PC-12 and PC-12/45 airplanes. This proposed AD would require you to inspect the pedestal leg assembly on aft facing passenger seats for correct configuration. If incorrectly configured, this proposed AD would require you to modify to the correct configuration. This proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. The actions specified by this proposed AD are intended to detect and correct pedestal leg assemblies on aft facing passenger seats that are in nonconformance with manufacturing standards. Nonconforming passenger seats could result in passenger injury in an emergency situation.
