Airworthiness Directives; Pacific Aerospace Limited Airplanes

FAA / Federal Register · 2021-15954

The FAA proposes to adopt a new airworthiness directive (AD) for certain Pacific Aerospace Limited Model 750XL airplanes. This proposed AD was prompted by 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 describes the unsafe condition as chafing damage in the port wing skin caused by the fuel system finger filters. This proposed AD would require inspecting the wing internal skin for chafing and taking any necessary corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
