Is AD 2013-05-18 a recurring Airworthiness Directive?

Yes — AD 2013-05-18 requires a repetitive inspection every 6000 hours. Next-due depends on the aircraft's time in service.

Airworthiness Directives; Rolls-Royce plc Turbofan Engines

What this AD requires

We are superseding an existing airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211 Trent 500 series turbofan engines. That AD currently requires a one-time inspection of the fuel tubes and fuel tube clips for evidence of damage, wear, and fuel leakage. This AD requires the same inspection, and adds additional repetitive inspections. This AD was prompted by additional RR engineering analysis. We are issuing this AD to prevent engine fuel leaks, which could result in engine damage and damage to the airplane.

Repetitive inspection. Re-inspect every 6000 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Part-conditional — FW57605, FW17689, FW57604, FK30710, FW57578, FK30713.

Applies only to engines that have any of the listed fuel tube part numbers installed (LP fuel tube wear against securing clips leading to fracture and fuel leakage).

Whether AD 2013-05-18 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.
