Airworthiness Directive · Amendment 39-22570 · Turbine engine compressor section
International Aero Engines, LLC Engines
This AD applies to International Aero Engines, LLC Model PW1124G1-JM, PW1127G-JM, PW1127GA-JM, PW1129G-JM, PW1130G-JM, PW1133G-JM, and PW1133GA-JM engines with an installed high-pressure compressor (HPC) rear hub, part number 30G4008 or 30G8208, with a serial number (S/N) listed in Table 2 or Table 3 of Pratt & Whitney Service Bulletin PW1000G-C-72-00-0209-00A-930A-D, Issue No: 002, dated June 20, 2023 (PW1000G-C-72-00-0209-00A-930A-D, Issue No: 002).
The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. That AD applies to certain International Aero Engines, LLC (IAE LLC) Model PW1124G1-JM, PW1127G- JM, PW1127GA-JM, PW1129G-JM, PW1130G-JM, PW1133G-JM, and PW1133GA-JM engines. As published, a part number was inadvertently excluded in the regulatory text of the AD. This document corrects that error. In all other respects, the original document remains the same.
At the next engine shop visit after the effective date of this AD, replace the HPC rear hub with a part eligible for installation.
(1) For the purpose of this AD, a “part eligible for installation” is:
(i) Any HPC rear hub with an S/N that does not appear in Table 2 or Table 3 of PW1000G-C-72-00-0209-00A-930A-D, Issue No: 002; or
(ii) Any HPC rear hub that has been serviced in accordance with Pratt & Whitney Service Bulletin PW1000G-C-72-00-0209-00A-930A-D (any revision).
(2) For the purpose of this AD, an “engine shop visit” is the induction of an engine into the shop for maintenance involving the separation of major mating engine flange H. The separation of engine flanges solely for the purpose of transportation without subsequent engine maintenance does not constitute an engine shop visit.
