AD 2021-01-03 Requires Removing Certain HPT 1st-Stage And HPT 2nd-Stage Disks From Service
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 highpressure 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. This AD is effective January 21, 2021.
