Airworthiness Directives; General Electric Company CF6-80A Series Turbofan Engines

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) CF6-80A series turbofan engines with a high-pressure turbine rotor (HPTR) stage 1 disk, part number (P/N) 9367M45G06, installed. This AD requires removing any HPTR stage 1 disk, P/N 9367M45G06, before exceeding 2,075 cycles-since-new (CSN). This AD results from an error by GE that incorrectly cited a cyclic life of 12,600 CSN for the HPTR stage 1 disk, P/N 9367M45G06. We are issuing this AD to prevent the HPTR stage 1 disk from exceeding its part life, which could cause fatigue cracks to start and grow. These cracks could result in a possible uncontained disk failure and damage to the airplane.

Which aircraft AD 2009-07-10 applies to

MakesGeneral Electric
ModelsCF6-80A, CF6-80A1, CF6-80A2, CF6-80A3
Part-conditional — 9367M45G06.

Applies only when a high-pressure turbine rotor (HPTR) stage 1 disk, P/N 9367M45G06, is installed. These engines are installed on, but not limited to, Airbus A310 series and Boeing 767 series airplanes.

Whether AD 2009-07-10 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 2009-07-10 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.
