AD NUMBER: 2019-06-01

PRODUCT: Certain International Aero Engines (IAE) PW1133G-JM, PW1133GA-JM, PW1130G-JM, PW1127G-JM, PW1127GAJM, PW1127G1-JM, PW1124G-JM, PW1124G1-JM, and PW1122G-JM turbofan engines.

ACTION: Final rule; request for comments.

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2018-24-01 for the engines listed above.

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.

DATES: This AD is effective April 10, 2019. Comments must be received by May 10, 2019.

COST: The FAA estimates that this AD affects 0 engines installed on airplanes of U.S. registry. Operators may incur the following costs in order to comply with this AD:

  • Remove and replace LPT 1st or 3rd-stage disk: 0 work-hours × $85 per hour = $0 per engine. Parts: $210,000. Cost per engine: $210,000
