Airworthiness Directives; General Electric Company CF34 Series Turbofan Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to General Electric Company CF34 series turbofan engines, that reduces the allowable operating cyclic life limit for affected high pressure compressor (HPC) stage 1 rotor disks. This amendment is prompted by an updated stress and life analysis. The actions specified by this AD are intended to prevent HPC stage 1 rotor disk rupture, engine failure, and damage to the aircraft.

Part-conditional — 6040T79G01.

Applies only to engines with high pressure compressor (HPC) stage 1 rotor disk P/N 6040T79G01 installed.

Whether AD 97-06-15 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 97-06-15 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.
