AD FAA-2025-2555

The FAA proposes to adopt a new airworthiness directive (AD) for certain International Aero Engines AG (IAE AG) Model V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, V2531-E5, and V2533-A5 engines. This proposed AD was prompted by a manufacturer investigation that revealed that certain 3rd stage HPC rotor blades were susceptible to shroud wear and blade failure. This proposed AD would require replacement of affected 3rd stage HPC rotor blades with parts eligible for installation. The FAA is proposing this AD to address the unsafe condition on these products.
