Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Model PC-12/47E airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as inward vent valves installed during production without chromate conversion coating on the bonding surface. This proposed AD would require modifying the inward vent valves and prohibiting installation of unmodified inward vent valves. The FAA is proposing this AD to address the unsafe condition on these products.
