While EASA has issued its final airworthiness directive, the FAA is yet to do so, despite publishing an NPRM in October 2023.

SUMMARY

·          EASA is targeting non-synchronous vibrations (NSV)

          on LEAP-1A engines, one of the two options for the 

          A320neo family.

·          Operators must evaluate NSV within 125 flight cycles 

          and replace parts as necessary.

·          FAA also proposed a directive for the same issue, 

          requiring inspections and calculations of NSV.

      The European Union Aviation Safety Agency (EASA) is targeting non-synchronous vibrations (NSV) on CFM International LEAP 1-A engines used on the Airbus A319neo, A320neo, and A321neo aircraft. The regulator noted cases of non-synchronous engine vibrations on these engines, which prompted the airworthiness directive (AD).
