Airworthiness Directives; General Electric Company Turbofan Engines

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) CF34-10E model turbofan engines. This AD was prompted by a manufacturer investigation that revealed Teflon material in the A-sump oil strainer (strainer assembly) screen after several reports of in-flight shutdowns (IFSDs) and unscheduled engine removals (UERs). This AD requires initial and repetitive visual inspections of the strainer assembly screen. As a terminating action to the initial and repetitive visual inspections, this AD requires the replacement of the stationary oil seal at the No. 1 forward bearing. The FAA is issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Part-conditional — B1316-00453, B1316-01274.

Applies only with a stationary oil seal, P/N B1316-00453 or B1316-01274, installed at the No. 1 forward bearing, that (1) has been repaired, overhauled, or entered into service after August 2014, and (2) has used high thermal stability oil or high performance capability oil for 56 flight hours (FHs) or more during the life of the stationary oil seal.

Whether AD 2022-05-08 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:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 2022-05-08 complied with on your aircraft?

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.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
