Is AD 2014-12-13 a recurring Airworthiness Directive?

Yes — AD 2014-12-13 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2014-12-13 apply to?

AD 2014-12-13 applies to Boeing — models 737-100, 737-200, 737-200C, 737-300, 737-400, 737-500, 737. 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) 2014-03-06 for all the Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. AD 2014-03-06 required repetitive inspections for cracking of the aft support fitting for the main landing gear (MLG) beam, and the rear spar upper chord and rear spar web in the area of rear spar station (RSS) 224.14; and repair if necessary. This AD clarifies two paragraph references. This AD was prompted by a determination that two paragraph references were in error. We are issuing this AD to detect and correct cracking of the aft support fitting for the main landing gear (MLG) beam, and the rear spar upper chord and rear spar web in the area of rear spar station (RSS) 224.14, which could grow and result in a fuel leak and possible fire.

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.

Installation of STC ST01219SE does not affect the ability to accomplish the actions required by this AD; a 'change in product' AMOC approval request is not necessary for airplanes on which that STC is installed.

Whether AD 2014-12-13 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.

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.
