Airworthiness Directive · Amendment 39-22039 · Aircraft fuel system
Pilatus Aircraft Ltd. Airplanes
This AD applies to Pilatus Aircraft Ltd. Model PC-12/47E airplanes, serial numbers 2001 and larger, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Model PC-12/47E 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 a batch of incorrectly sized fuel transfer ejector nozzles that were installed on Model PC-12/47E airplanes during production. This AD requires removing the affected fuel transfer ejectors from service and prohibits installation of the affected fuel transfer ejectors. The FAA is issuing this AD to address the unsafe condition on these products.
(1) For purposes of this AD, an “affected fuel transfer ejector” is a fuel transfer ejector part number (P/N) 968.84.71.112 with a serial number listed in the table on page 1 in section 1.C. of Pilatus PC-12 Service Bulletin No. 28-014, dated August 12, 2020 (Pilatus SB 28-014).
(2) For purposes of this AD, a “Group 1 airplane” is an airplane with an affected fuel transfer ejector installed.
(3) For purposes of this AD, a “Group 2 airplane” is an airplane without an affected fuel transfer ejector installed.
For Group 1 airplanes: Within 4 months after the effective date of this AD, remove each fuel transfer ejector from service and install a serviceable part in accordance with Paragraph 3.B.(1) of the Accomplishment Instructions in Pilatus SB 28-014.
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.
