AD 2021-23-16 86 FR 69161

The FAA is adopting a new airworthiness directive (AD) for certain Pacific Aerospace Limited Model 750XL airplanes. This 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 identifies the unsafe condition as chafing of the engine fuel feed line hoses. This AD requires inspecting the engine fuel feed line hoses and the electrical wiring and rerouting all fuel lines. The FAA is issuing this AD to address the unsafe condition on these products.
