Airworthiness Directive · Amendment 39-21728 · Turbine section
International Aero Engines, LLC Turbofan Engines
This AD applies to International Aero Engines, LLC (IAE) PW1122G-JM, PW1124G1-JM, PW1124G-JM, PW1127G1-JM, PW1127GA-JM, PW1127G-JM, PW1129G-JM, PW1130G-JM, PW1133GA-JM, and PW1133G-JM model turbofan engines with an installed:
(1) High-pressure turbine (HPT) 1st-stage disk, part number (P/N) 30G6201 or 30G7301, with a serial number (S/N) listed in Figure 1 to paragraph (c) of this AD; or
(2) HPT 2nd-stage disk, P/N 30G5502 or 30G6602, with an S/N listed in Figure 2 to paragraph (c) of this AD.
The FAA is adopting a new airworthiness directive (AD) for certain International Aero Engines, LLC (IAE) PW1122G-JM, PW1124G1-JM, PW1124G-JM, PW1127G1-JM, PW1127GA-JM, PW1127G-JM, PW1129G-JM, PW1130G- JM, PW1133GA-JM, and PW1133G-JM model turbofan engines. This AD was prompted by a root cause analysis of an event involving an uncontained failure of a high-pressure turbine (HPT) disk that resulted in high- energy debris penetrating the engine cowling on an Airbus Model A321- 231 airplane, powered by IAE V2533-A5 model turbofan engines. This AD requires removing certain HPT 1st-stage and HPT 2nd-stage disks from service. The FAA is issuing this AD to address the unsafe condition on these products.
(1) For IAE model turbofan engines with an HPT 1st-stage disk, P/N 30G6201 or 30G7301, with an S/N listed in Figure 1 to paragraph (c) of this AD, within 30 days after the effective days of the AD, remove the HPT 1st-stage disk from service.
(2) For IAE model turbofan engines with an HPT 2nd-stage disk, P/N 30G5502 or 30G6602, with an S/N listed in Figure 2 to paragraph (c) of this AD, within 30 days after the effective days of the AD, remove the HPT 2nd-stage disk from service.
