Airworthiness Directives; General Electric Company Turbofan Engines

What this AD requires

We are adopting a new airworthiness directive (AD) for General Electric Company (GE) CF6-80C2L1F turbofan engines. This AD was prompted by a reduction in the life limit of the affected engines which is the result of a revised operating profile. This AD requires replacement of the high-pressure turbine (HPT) spacer/impeller, part number (P/N) 1539M12P02, at a newer, lower life limit. We are issuing this AD to correct the unsafe condition on these products.

Which aircraft AD 2017-11-15 applies to

MakesGeneral Electric Company
ModelsCF6-80C2L1F, CF6-80C2
Part-conditional — 1539M12P02.

Applies to engines with a high-pressure turbine (HPT) spacer/impeller, P/N 1539M12P02, installed.

Whether AD 2017-11-15 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 2017-11-15 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.
