Airworthiness Directives; McDonnell Douglas Model MD-11 and MD-11F Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 and MD-11F airplanes that requires an inspection to detect chafed wires in the avionics equipment compartment, and repair, if necessary. This amendment also requires replacement of the existing cover of the avionics cooling fan with a new cover, and installation of a new placard on the cover. Additionally, this amendment specifies which previously accomplished actions are acceptable for compliance with certain requirements of this AD; and clarifies the applicability, a part number, and the inspection definition. The actions specified by this AD are intended to ensure that the cover of the avionics cooling fans is removed only for fan maintenance, and to prevent smoke and/or fire in the avionics equipment compartment due to chafing and arcing as a result of maintenance personnel lying against the removed cover and/ or insulation blankets that cover wire harnesses. This action is intended to address the identified unsafe condition.

Whether AD 03-9426 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 03-9426 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.
