Airworthiness Directive · Amendment 39-21285 · Doors
Pilatus Aircraft Ltd. Airplanes
This AD applies to Pilatus Aircraft Ltd. Model PC-24 airplanes, all serial numbers, with an emergency exit grommet part number (P/N) 944.87.32.001 installed, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd Model PC-24 airplanes. This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as the vinyl grommets on the upper panel assembly on the left-hand (LH) and right-hand (RH) emergency exits becoming rigid after exposure to low temperatures, which could result in failure of the emergency exits to open during an evacuation. This AD requires replacing the grommets. The FAA is issuing this AD to address the unsafe condition on these products.
Unless already done, do the following actions in paragraphs (f)(1) and (2) of this AD.
(1) Within 3 months after the effective date of this AD, replace each grommet P/N 944.87.32.001 holding the upper panel assembly in position on the LH and RH emergency exits with grommet P/N 525.26.24.035 in accordance with the Accomplishment Instructions, section 3.B., of Pilatus Aircraft Ltd PC-24 Service Bulletin No. 25-005, dated August 12, 2019.
(2) As of the effective date of this AD, do not install a grommet P/N 944.87.32.001 on any airplane.
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.
