Airworthiness Directive 2022-10-04
one-timeAirworthiness Directives; Engine Alliance Turbofan Engines
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain Engine Alliance (EA) GP7270, GP7272, and GP7277 model turbofan engines. This AD was prompted by a manufacturer investigation that revealed certain stages 7-9 compressor rotor spools were manufactured from a billet of material suspected of having foreign material embedded. This AD requires the replacement of the affected stages 7-9 compressor rotor spool. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2022-10-04 applies to
Applies only with an installed Stages 7-9 compressor rotor spool: P/N 2031M90G05 with S/N GWN0R7R3; or P/N 2031M90G07 with S/N GWN0R9R3, GWN0R9TC, GWN0R9TM, GWN0RCT5, or GWN0RCT6.
Whether AD 2022-10-04 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
