Is AD 2014-05-13 a recurring Airworthiness Directive?

Yes — AD 2014-05-13 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2014-05-13 apply to?

AD 2014-05-13 applies to Boeing — models 757-200, 757-200PF, 757-200CB, 757. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; The Boeing Company Airplanes

What this AD requires

We are superseding Airworthiness Directive (AD) 2004-12-07 for certain The Boeing Company Model 757 series airplanes equipped with Rolls-Royce RB211 engines. AD 2004-12-07 required modification of the nacelle strut and wing structure; and for certain airplanes, repetitive detailed inspections of certain aft bulkhead fasteners for loose or missing fasteners, and corrective action if necessary. For certain other airplanes, AD 2004-12-07 required a one-time detailed inspection of the middle gusset of the inboard side load fitting for proper alignment, and realignment if necessary; a one-time eddy current inspection of certain fastener holes for cracking, and repair if necessary; and a detailed inspection of certain fasteners for loose or missing fasteners, and replacement with new fasteners if necessary. This new AD specifies a maximum compliance time limit. This AD was prompted by reports indicating that the actual operational loads applied to the nacelle are higher than the analytical loads that were used during the initial design. We are issuing this AD to prevent fatigue cracking in primary strut structure and consequent reduced structural integrity of the strut.

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

Serial-conditional — narrows to serials 1–735.

Applies to airplanes with line numbers 1 through 735 inclusive, equipped with Rolls-Royce RB211 engines.

Whether AD 2014-05-13 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 2014-05-13 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.
