Airworthiness Directives; the Boeing Company Airplanes

What this AD requires

We are superseding Airworthiness Directive (AD) 89-12-10, for certain The Boeing Company Model 747 airplanes. AD 89-12-10 required replacement of certain underwing fuel tank access doors with stronger, fire-resistant doors. This new AD requires inspecting certain fuel tank access doors for installation of impact-resistant doors, and stencils and index markers; corrective actions if necessary; revising the maintenance program to incorporate certain new airworthiness limitations; and adding airplanes to the applicability. This AD was prompted by a report of a standard access door installed instead of an impact-resistant access door and stencils missing from some impact- resistant access doors and adjacent wing skin. We are issuing this AD to prevent foreign object penetration of the fuel tank, which could cause a fuel leak near an ignition source (e.g., hot brakes or engine exhaust nozzle), consequently leading to a fuel-fed fire.

Applies to airplanes identified in Boeing Service Bulletin 747-28-2315, dated January 11, 2012.

Whether AD 2014-15-14 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 2014-15-14 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.
