Applicability*9
This AD applies to Pilatus Aircraft Ltd. Model PC-12/47E airplanes, serial numbers 2001 and larger, certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
(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.
Unsafe condition
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 a batch of incorrectly sized fuel transfer ejector nozzles that were installed on Model PC-12/47E airplanes during production. The FAA is issuing this AD to correct the installation of incorrectly sized fuel transfer ejectors nozzles. If not addressed, this unsafe condition could result in a restriction of motive fuel flow due to ice accumulation and lead to a reduction of safety margins in the fuel system with loss of engine power or engine shutdown.
Affected ADs
None.
