Summary
We propose to adopt a new airworthiness directive (AD) for certain International Aero Engines (IAE) PW1133G-JM, PW1133GA-JM, PW1130G-JM, PW1127G-JM, PW1127GA-JM, PW1127G1-JM, PW1124G-JM, PW1124G1- JM, and PW1122G-JM turbofan engines with a certain high-pressure compressor (HPC) front hub installed. This proposed AD was prompted by corrosion found on the HPC front hub. This proposed AD would require replacing the HPC front hub with a part eligible for installation. We are proposing this AD to address the unsafe condition on these products.
