Abstract
The FAA is adopting a new airworthiness directive (AD) for certain International Aero Engines, LLC (IAE LLC) PW1122G-JM, PW1124G- JM, PW1124G1-JM, PW1127G1-JM, PW1127GA-JM, PW1127G-JM, PW1129G-JM, PW1130G-JM, PW1133GA-JM, PW1133G-JM model turbofan engines. This AD requires replacement of certain low-pressure turbine (LPT) 3rd-stage blades. This AD was prompted by multiple reports of LPT 3rd-stage blade failures causing a reduction of engine thrust. The FAA is issuing this AD to address the unsafe condition on these products.
