Airworthiness Directive · Amendment 39-21880 · Fuel dump system
Pilatus Aircraft Ltd. Airplanes
This AD applies to Pilatus Aircraft Ltd. Model PC-24 airplanes, serial numbers 101 through 184, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Model PC-24 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 describes the unsafe condition as insufficient performance of the fuel drain system that could lead to fire and damage of the airplane. This AD requires modifying the fuel drain pipe routing and installing a drain mast. The FAA is issuing this AD to address the unsafe condition on these products.
Within 5 months after the effective date of this AD, modify the fuel drain pipe routing and install the drain mast by following paragraphs A. and B. of the Accomplishment Instructions in Pilatus PC-24 Service Bulletin No. 28-003, Revision 1, dated January 23, 2020.
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.
