Airworthiness Directive · Amendment 39-21770 · Aircraft fuel system
Pacific Aerospace Limited Airplanes
This AD applies to Pacific Aerospace Limited Model 750XL airplanes, serial numbers 100 through 205, 207 through 213, and 8001, certificated in any category.
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 damage in the port wing skin caused by the fuel system finger filters. This AD requires inspecting the wing internal skin for chafing and taking any necessary corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
Within 165 hours time-in-service after the effective date of this AD, modify the LH inspection panel assembly and inspect the LH wing and fuel tank for chafing, and then, before further flight, repair any chafing and install the panels in accordance with the Accomplishment Instructions in Pacific Aerospace Limited Mandatory Service Bulletin PACSB/XL/099, Issue 1, dated January 16, 2019.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
