We propose to adopt a new airworthiness directive (AD) for all 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 certain low-pressure turbine (LPT) 1st- and 3rd-stage disks installed. This proposed AD was prompted by a report of manufacturing defects found on delivered LPT 1st- and 3rd- stage disks. This proposed AD would require removing the LPT 1st- or 3rd-stage disk from service and replacing with a part eligible for installation. We are proposing this AD to address the unsafe condition on these products.
