Airworthiness Directive · Amendment 39-21182 · Power plant
Pacific Aerospace Limited Airplanes
This AD applies to Pacific Aerospace Limited Model 750XL airplanes, serial numbers up to and including 221, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for Pacific Aerospace Limited Model 750XL airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 ineffective firewall sealing for firewall wiring penetrations. The FAA is issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, within 3 months after August 19, 2020 (the effective date of this AD) or within 300 hours time-in-service after August 19, 2020 (the effective date of this AD), whichever occurs first, install new sealant components into the main loom firewall penetration hole and the ADAS or DAAM firewall penetration holes if installed by following the Accomplishment Instructions in Pacific Aerospace Mandatory Service Bulletin PACSB/XL/101, Issue 1, dated May 9, 2018, except you are not required to contact Pacific Aerospace Limited if there is any chafing or damage on a loom. Instead, your repair must be accomplished before further flight using a method approved by the Manager, Small Airplane Standards Branch, FAA, using the contact information in paragraph (g) of this AD, or approved by the Civil Aviation Authority (CAA) of New Zealand. For a repair method to be approved as required by this paragraph, the FAA or CAA approval letter must specifically refer to this AD.
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.
