Is AD E6-12827 a recurring Airworthiness Directive?

No — AD E6-12827 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD E6-12827 apply to?

AD E6-12827 applies to Mcdonnell Douglas — models DC-10-10F, DC-10-30, DC-10-30F, DC-10-40, DC-10-40F. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-30, DC-10-30F (KDC-10), DC-10-40, and DC-10-40F Airplanes

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas airplanes, identified above. This AD requires reducing the length of the sump drain collar and replacing the fuel tank sump drain lockring for fuel tanks 1, 2, and 3; and reducing the length of the drain outlet barrel for the auxiliary fuel tank, if applicable. For airplanes with an auxiliary fuel tank, this AD also requires relocating the sump drain outlet to allow draining the sumps without opening the doors of the main landing gear wheel well. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to reduce the potential of ignition sources inside fuel tanks in the event of a lightning strike, which, in combination with flammable fuel vapors, could result in arcing in the fuel tank, fuel tank explosions, and consequent loss of the airplane.

Whether AD E6-12827 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 E6-12827 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.
