Is AD 2003-05-04 a recurring Airworthiness Directive?

Yes — AD 2003-05-04 requires a repetitive inspection every 2000 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2003-05-04 apply to?

AD 2003-05-04 applies to Rolls-Royce — models Tay 620-15, Tay 650-15, Tay 611-8, Tay 651-54, Tay. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Rolls-Royce Deutschland Ltd. & Co KG, Model Tay 611-8, 620-15, 650-15, and 651-54 Turbofan Engines

What this AD requires

This amendment supersedes an existing airworthiness directive (AD) that is applicable to Rolls-Royce Deutschland Ltd. & Co KG (RRD) Model Tay 620-15 and 650-15 turbofan engines. That AD currently requires initial and repetitive inspections of certain low pressure (LP) fuel tubes. This amendment requires the same inspections and adds two engine models to the applicability. This amendment is prompted by a report that certain Tay 611-8 and 651-54 turbofan engines may use the same LP fuel tube. The actions specified in this AD are intended to prevent a dual-engine flameout due to fuel exhaustion, which could lead to forced landing and possible damage to the airplane.

Repetitive inspection. Re-inspect every 2000 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

LP fuel tube (P/N JR33021A) fretting inspection on Tay 620-15/650-15 and Tay 611-8/651-54 turbofan engines; the 611-8/651-54 compliance schedule additionally depends on whether Part 4 of RRD SB TAY-73-1194 is incorporated and accumulated hours TIS (>=4,000 vs <4,000).

Whether AD 2003-05-04 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.
