Summary
The FAA is adopting a new airworthiness directive (AD) for all International Aero Engines, LLC (IAE) PW1133G-JM, PW1133GA-JM, PW1130G- JM, PW1129G-JM, PW1127G-JM, PW1127GA-JM, PW1127G1-JM, PW1124G-JM, PW1124G1-JM, and PW1122G-JM model turbofan engines. This AD requires the removal of the main gearbox (MGB) assembly and electronic engine control (EEC) software and the installation of a part and software version eligible for installation. This AD was prompted by multiple reports of in-flight engine shutdowns (IFSDs) as the result of high- cycle fatigue causing fracture of certain parts of the MGB assembly. The FAA is issuing this AD to address the unsafe condition on these products.
