The FAA has issued a notice of proposed rule-making for the CFM LEAP-1A, requiring inspection and the replacement of certain parts after multiple take-off aborts have been reported caused by compressor stall of the engine. The LEAP-1A powers the Airbus A320neo family.
The NRPM was published on Tuesday. It says that “the FAA was notified by the engine manufacturer of three aborted takeoffs and two air-turn back (ATBs) caused by High-Pressure Compressor stall. Additional manufacturer investigation revealed that wear on the No. 3 bearing spring finger housing can lead to high levels of non-synchronous vibration (NSV), which could induce HPC stall.”
