Airworthiness Directive · Amendment 39-21381 · Electrical power system wiring
Pilatus Aircraft Ltd. Airplanes
This AD applies to Pilatus Aircraft Ltd. Model PC-24 airplanes, serial numbers 101 through 160 inclusive, 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 results from 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 electrical harness installations on PC-24 airplanes that are not in compliance with the approved design. This unsafe condition could lead to wire chafing and potential arcing or failure of wires having the incorrect length, possibly resulting in loss of system redundancy, or generation of smoke and smell, or loss of power plant fire protection function. This AD requires modifying the electrical harness installation. The FAA is issuing this AD to address the unsafe condition on these products.
Unless already accomplished, during the next annual inspection after the effective date of this AD or within 12 months after the effective date of this AD, whichever occurs later, modify the electrical harness installation in accordance with sections 3.A. through 3.H. of the Accomplishment Instructions in Pilatus PC-24 Service Bulletin No. 91-001, dated April 7, 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.
