## Summary

We propose to adopt a new airworthiness directive (AD) for certain International Aero Engines AG (IAE) V2522-A5, V2524-A5, V2527- A5, V2527E-A5, V2527M-A5, V2530-A5, V2533-A5, V2525-D5, V2528-D5, and V2531-E5 turbofan engines. This proposed AD was prompted following a self-disclosure by IAE regarding manufacturing quality escapes. This proposed AD would require replacing the affected and suspect parts within the time limits specified in the compliance section. We are proposing this AD to correct the unsafe condition on these products.
