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

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model MD-11 and MD-11F airplanes. This AD requires inspecting the power feeder cables of the auxiliary power unit (APU) for chafing damage, and accomplishing any related corrective action. This AD also requires modifying the drain line of the fuel feed shroud of the horizontal stabilizer. This AD is prompted by a report of the drain line of the fuel feed shroud riding on the power feeder cables of the APU. We are issuing this AD to prevent chafing of the power feeder cables of the APU, which could result in electrical arcing to adjacent structure and consequent fire in the airplane.

Whether AD 05-1557 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 05-1557 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.
