Summary
The FAA is adopting 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 AD was prompted by a manufacturer investigation that revealed that certain 3rd stage high pressure compressor (HPC) rotor blades were susceptible to shroud wear and blade failure. This AD requires replacement of affected 3rd stage HPC rotor blades with parts eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.
