Model PC-12/47E airplanes, serial numbers 2001 and larger, certificated in any category. (d) SUBJECT Joint Aircraft Service Component (JASC) Code: 2800, Aircraft Fuel Sys- tem. (e) 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 PC12/47E 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.
