Notice of proposed rulemaking (NPRM).
Summary
The FAA proposes to adopt a new airworthiness directive (AD) for IAE V2500-A1, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, and V2533- A5 turbofan engines. This proposed AD would require a onetime inspection of certain vortex reducers for cracks, and replacing the reducer and high-pressure (HP) compressor stage 3-8 drum if the reducer is cracked. This proposed AD results from reports of fractured vortex reducers found at shop visits. We are proposing this AD to inspect for cracks in the vortex reducer. Cracks in the vortex reducer could cause an uncontained failure of the HP compressor stage 3-8 drum, which could result in damage to the airplane.
