AD: General Electric Company Turbofan Engines

AD NUMBER: 2017-08-05

PRODUCT: All General Electric Company (GE) GE90-76B, GE90-77B, GE90-85B, GE90-90B, and GE90-94B turbofan engines.

ACTION: Final Rule

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2016-13-05 for the engines listed above.

AD 2016-13-05 required eddy current inspection (ECI) of the high-pressure compressor (HPC) stage 8-10 spool at each shop visit for all affected engines and ECI or ultrasonic inspection (USI) for certain affected engines.

This new AD requires initial and repetitive on-wing USIs of the HPC stage 8-10 spool for certain engines prior to shop visit and ECI of all affected engines at each shop visit.

This AD was prompted by analysis that the risk of the failure of an HPC stage 8-10 spool was excessive without repetitive USI prior to shop visit.

The FAA is issuing this AD to correct the unsafe condition on these products.

DATES: This AD is effective May 19, 2017.

FMI: AD
