Is AD 2013-09-02 a recurring Airworthiness Directive?

Yes — AD 2013-09-02 requires a repetitive inspection every 9 months. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2013-09-02 apply to?

AD 2013-09-02 applies to The Boeing Company — 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 two existing airworthiness directives (AD) that apply to certain The Boeing Company Model 737-100, -200, -200C, - 300, -400, and -500 series airplanes. Those ADs, for certain airplanes, currently require repetitive inspections of the flap track of the wing outboard flap, and corrective actions if necessary; and eventual rework of the flap track assembly and rear spar attachments. For certain airplanes, this new AD adds repetitive inspections, scheduled overhauls, correct alignment during installation, and repetitive maintenance of the flap track, and corrective actions if necessary. This new AD also adds airplanes to the applicability. This AD was prompted by reports that the work sequence and procedures used during installation of replacement tracks could cause loose or cracked tracks. We are issuing this AD to detect and correct cracking and damage in the flap track, which could cause loss of the outboard trailing edge flap and consequent reduced controllability of the airplane.

Repetitive inspection. Re-inspect every 9 months. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Part-conditional — ST01219SE.

Installation of STC ST01219SE does not affect applicability; a change-in-product AMOC approval is not necessary for airplanes with that STC installed.

Whether AD 2013-09-02 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.
