## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain International Aero Engines AG (IAE) V2500-A1, V2522-A5, V2524- A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, V2531-E5, and V2533-A5 model turbofan engines. This AD was prompted by a root cause analysis of an event involving an uncontained failure of a high-pressure turbine (HPT) 1st-stage disk that resulted in high-energy debris penetrating the engine cowling. This AD requires removing certain HPT 1st-stage and HPT 2nd-stage disks from service. The FAA is issuing this AD to address the unsafe condition on these products.
