FAA Orders GE Engine Disk Swaps for Safety
Published Date: 6/3/2025
Rule
Summary
The FAA is making some important changes for certain General Electric jet engines because some parts might have tiny metal bits that could cause problems. If you have these engines, you’ll need to swap out specific turbine disks to keep flying safe. This update affects airlines and maintenance crews and means they’ll need to act soon to avoid costly issues.
Analyzed Economic Effects
3 provisions identified: 1 benefits, 2 costs, 0 mixed.
Required Replacement of HPT Stage 1 & 2 Disks
The AD requires replacement of affected high-pressure turbine (HPT) stage 1 and HPT stage 2 disks with parts eligible for installation. Operators and maintenance providers must remove and replace those specific disks to comply with the directive.
Which GE GEnx Engines Are Covered
This airworthiness directive (AD) applies to specific General Electric GEnx engine models: 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, and GEnx-2B67/P. If you operate or maintain any of these engines, this AD applies to those engines.
Fixes Unsafe Iron Inclusion Risk
The AD was issued after an investigation found certain HPT stage 1 and stage 2 disks may have powder metal material suspected to contain iron inclusion. Replacing the affected disks is intended to address that unsafe condition and improve flight safety for passengers and crews.
