Airworthiness Directives; McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, and DC-10-30F (KC-10A and KDC-10) Airplanes; Model DC-10-40 and DC-10-40F Airplanes Equipped With Pratt & Whitney JT9-20 or JT9-20J Engines; and Model MD-10-10F and MD-10-30F Airplanes

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for the McDonnell Douglas airplanes previously described. This AD requires replacing the control modules of the fire detection systems of the propulsion engines with new, improved control modules. This AD results from a report of broken or severed wiring between engine fire detectors and the fire detection system control module, which caused the fire detection system to become non-functional without flightcrew awareness. We are issuing this AD to prevent unannunciated fire in a propulsion engine, which could cause injury to flightcrew and passengers or loss of the airplane.

All Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, and DC-10-30F (including KC-10A and KDC-10 military variants) airplanes apply regardless of engine. Model DC-10-40 and DC-10-40F airplanes apply only when equipped with Pratt & Whitney JT9-20 or JT9-20J engines. All Model MD-10-10F and MD-10-30F airplanes apply.

Whether AD 2007-04-17 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 2007-04-17 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.
