## Abstract

We are superseding Airworthiness Directive (AD) 2018-24-01 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. AD 2018-24-01 required removing certain low-pressure turbine (LPT) 1st- and 3rd-stage disks from service and replacing with a part eligible for installation. This AD retains the same requirements as AD 2018-24-01. This AD was prompted by the discovery of incorrect serial numbers in the identification of LPT disks in AD 2018-24-01. We are issuing this AD to address the unsafe condition on these products.
