Is AD 2008-10-09 a recurring Airworthiness Directive?

Yes — AD 2008-10-09 requires a repetitive inspection every 120 months. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2008-10-09 apply to?

AD 2008-10-09 applies to Boeing — models 737-100, 737-200, 737-200C, 737-300, 737-400, 737-500. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Boeing Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for all Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires revising the FAA-approved maintenance program to incorporate new airworthiness limitations (AWLs) for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This AD also requires the initial inspection of a certain repetitive AWL inspection to phase in that inspection, and repair if necessary. This AD results from a design review of the fuel tank system. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

Repetitive inspection. Re-inspect every 120 months. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

serial/model applicability read from the AD body — confirm the exact serial/model from the records

Whether AD 2008-10-09 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.
