Airworthiness Directives; Pacific Aerospace Limited Airplanes

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 installation of the wing leading edge tank fuel pickup assembly in a pre-stressed condition, which could cause cracks in the wing spar web or the fuel pickup assembly pipe. This AD requires inspecting the angle of the support bracket on the wing leading edge tank fuel pickup assembly and taking any necessary corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
