Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Model PC-12/47E airplanes. This AD was prompted by a report of the stall warning protection system (SWPS) engaging when not appropriate. This AD requires updating operational software and incorporating a pilot's operating handbook (POH) temporary revision (TR). This AD also prohibits the installation of affected software. The FAA is issuing this AD to address the unsafe condition on these products.
