FAA Discovers Jet Engine Parts Have Shorter Lifespans Than Expected

## Summary

The FAA is making new rules for certain General Electric GEnx engines to keep them safe. They found some engine parts might wear out sooner than expected, so they’re requiring one-time inspections and possible replacements by February 12, 2025. Airlines with these engines should get ready to check and fix parts, which might cost some time and money but keeps flights safe and sound.

## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) Model GEnx-1B64, GEnx-1B64/P1, GEnx-1B64/P2, GEnx-1B67, GEnx-1B67/P1, GEnx-1B67/P2, GEnx-1B70, GEnx- 1B70/75/P1, GEnx-1B70/75/P2, GEnx-1B70/P1, GEnx-1B70/P2, GEnx-1B70C/P1, GEnx-1B70C/P2, GEnx-1B74/75/P1, GEnx-1B74/75/P2, GEnx-1B76/P2, GEnx- 1B76A/P2, GEnx-2B67, GEnx-2B67B, and GEnx-2B67/P engines. This AD was prompted by a manufacturer evaluation that determined a lower life limit may be necessary for certain stages 6-10 compressor rotor spools than allowed by the engine shop manual (ESM). This AD requires a one- time inspection of the stages 6-10 spools for previously accomplished blend repairs, a one-time inspection of the blend repairs on the stages 6-10 spools for compliance with the updated allowable limits, and replacement if necessary. The FAA is issuing this AD to address the unsafe condition on these products.

## Effects PRIA read

- Mandatory one-time spool inspections: cost, high. If your airplane has one of the listed GE GEnx-1B or GEnx-2B engines with an affected stages 6-10 compressor rotor spool, you must do a one-time inspection for previous blend repairs and inspect any repairs for compliance with updated allowable limits. If a blend repair is out of limits, the spool…
- Estimated inspection and replacement costs: cost, high. The FAA estimates this AD affects 6 engines on U.S. registry. Estimated inspection costs are 8 work-hours ($680) to inspect the stages 6-10 spool and 1 work-hour ($85) to inspect previous blend repairs per product; for U.S. operators those inspection costs are listed as $4,080 and $510 respectively…
- Compliance timing and deadline rule: cost, low. The AD requires the inspections to be done at the next piece-part exposure after the AD effective date or before the affected spool reaches the cyclic removal threshold listed in the GE service bulletin, whichever occurs first. The AD became effective February 12, 2025. Operators may take credit if…
