Is AD 2003-05-10 a recurring Airworthiness Directive?

Yes — AD 2003-05-10 requires a repetitive inspection every 200 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2003-05-10 apply to?

AD 2003-05-10 applies to General Electric — models CF34-AL, CF34-BJ, CF34. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

This amendment supersedes an existing airworthiness directive (AD), that is applicable to General Electric Company (GE) CF34-3A1, - 3B, and -3B1 turbofan engines with scavenge screens part numbers (P/Ns) 4047T95P01 and 5054T86G02 installed in the B-sump oil scavenge system. That AD currently requires initial and repetitive visual inspections and cleaning of the B-sump scavenge screens. This amendment requires initial and repetitive visual inspections and cleaning of the B-sump scavenge screens until a screenless fitting is installed. This amendment is prompted by six reports of B-sump oil scavenge system failure causing engine in-flight shutdowns. The actions specified by this AD are intended to prevent B-sump scavenge screen blockage due to coking, which could result in ignition of B-sump oil in the secondary air system, fan drive shaft separation, and uncontained engine failure.

Repetitive inspection. Re-inspect every 200 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

B-sump oil scavenge screen (P/Ns 4047T95P01 and 5054T86G02) inspection/cleaning schedule on CF34 turbofan engines per GE Alert SBs CF34-AL S/B 79-A0014 and CF34-BJ S/B 79-A0015; interval depends on hours since new/since last shop visit.

Whether AD 2003-05-10 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.

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.
