## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain 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 proposed AD was prompted by reports of failures of certain low-pressure turbine (LPT) 3rd-stage blades. This proposed AD would require replacement of the affected LPT 3rd-stage blades. The FAA is proposing this AD to address the unsafe condition on these products.
