Airworthiness Directives; McDonnell Douglas Corporation Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, and MD-10-30F Airplanes

What this AD requires

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Model DC-10-10, DC-10-10F, DC-10-15, DC- 10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, and DC-10-40F airplanes. That AD currently requires installing or replacing with improved parts, as applicable, the bonding straps between the metallic frame of the fillet and the wing leading edge ribs, on both the left and right sides of the airplane. This new AD revises the applicability by adding and removing certain airplanes. This new AD requires, for certain airplanes, repositioning or replacing two bonding straps, and doing a bonding-resistance check and an inspection to determine correct installation of certain bonding straps, and applicable corrective actions. 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 severe lightning strike, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

Applicability determined by manufacturer's fuselage number identified in the applicable service bulletin: Boeing Service Bulletin DC10-53-109, Revision 7, dated March 3, 2009, for airplanes with extended wing-to-fuselage fillets; or DC10-53-111, Revision 6, dated March 3, 2009, for airplanes with conventional wing-to-fuselage fillets. MD-10-10F and MD-10-30F airplanes are DC-10 series airplanes converted to MD-10 configuration; KC-10A and KDC-10 are military variants of the DC-10-30F.

Whether AD 2009-26-17 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.

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.
