Abstract
The FAA is adopting a new airworthiness directive (AD) for certain International Aero Engines, LLC (IAE) PW1122G-JM, PW1124G1-JM, PW1124G-JM, PW1127G1-JM, PW1127GA-JM, PW1127G-JM, PW1129G-JM, PW1130G- JM, PW1133GA-JM, and PW1133G-JM 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) disk that resulted in high- energy debris penetrating the engine cowling on an Airbus Model A321- 231 airplane, powered by IAE V2533-A5 model turbofan engines. 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.
