Is AD 2008-05-01 a recurring Airworthiness Directive?

No — AD 2008-05-01 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2008-05-01 apply to?

AD 2008-05-01 applies to General Electric — models 8C1, 8C5, 8C5B1, 8E5, 8E5A1, 10E, CF34. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; General Electric Company CF34-8C1/-8C5/-8C5B1/-8E5/-8E5A1, and CF34-10E Series Turbofan Engines

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) CF34-8C1/-8C5/-8C5B1/-8E5/-8E5A1, and CF34-10E series turbofan engines with certain part number (P/N) and serial number (SN) fuel metering units (FMU) installed. This AD requires a onetime test of the FMU for a miswired (reversed polarity) condition of the input wires to the overspeed solenoid. This AD results from the discovery of miswired FMU overspeed solenoids in the field. We are issuing this AD to prevent the engine from failing to shutdown during an overspeed which may lead to uncontained engine failure.

Whether AD 2008-05-01 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 2008-05-01 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.
