Airworthiness Directives; Fokker Services B.V. Airplanes

概要

We propose to adopt a new airworthiness directive (AD) for Fokker Services B.V. Model F28 Mark 0100 series airplanes equipped with Rolls-Royce TAY 650-15 engines. This AD was prompted by reports of uncontained engine fan blade failures in Rolls-Royce TAY 650-15 engines. The fan blade failures occurred due to cracking of the fan blades, which was initiated under conditions of fan blade flutter during engine ground operation. This proposed AD would require installation of a caution placard in the flight compartment. We are proposing this AD to prevent certain engine thrust settings during ground operation, which can cause the fan blades to flutter and fail, resulting in damage to the airplane and possible injury to personnel.
