Is AD 2003-10-01 a recurring Airworthiness Directive?

No — AD 2003-10-01 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2003-10-01 apply to?

AD 2003-10-01 applies to General Electric Company — models CF6-6. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; General Electric Company CF6-6 Series Turbofan Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD), that is applicable to General Electric (GE) CF6-6 series turbofan engines. This amendment requires a reduction of the cyclic life limit for certain high pressure turbine rotor (HPTR) rear shafts, and requires removing certain HPTR rear shafts from service before exceeding the new, lower cyclic life limit. In addition, this amendment requires removing from service certain HPTR rear shafts that currently exceed, or will exceed, the new, lower cyclic life limit according to the compliance schedule described in this AD. This amendment is prompted by an updated low-cycle-fatigue (LCF) analysis performed by the manufacturer that resulted in a lower cyclic life limit for certain HPTR rear shaft part numbers (PNs) installed in CF6-6 engines. The actions specified by this AD are intended to prevent cracks in HPTR rear shafts that could result in uncontained engine failure and damage to the airplane.

Applies to engines with an installed HPTR (high-pressure turbine rotor) rear shaft bearing one of the listed part numbers; removal schedule and a new 8,950-CSN life limit depend on cycles-since-new already accumulated on the shaft (Table 1).

Whether AD 2003-10-01 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 2003-10-01 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.
