Airworthiness Directive E7-10110
one-timeAirworthiness Directives; McDonnell Douglas Model DC-10-30 and DC-10-30F (KC-10A and KDC-10) Airplanes, Model DC-10-40 and DC-10-40F Airplanes, and Model MD-10-30F Airplanes
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model DC-10-30 and DC-10-30F (KC-10A and KDC- 10) airplanes, Model DC-10-40 and DC-10-40F airplanes, and Model MD-10- 30F airplanes. This AD requires installing bracket assemblies and jumper wires in the center main wheel well to improve the bonding path between the structure (wall) of the lower auxiliary fuel tank and its internal fuel pumps; measuring the electrical resistance between the fuel pump housings and the fuel tank structure; and doing corrective actions if necessary. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to detect and correct an inadequate bond between the internal fuel pump housings and the structure of the lower auxiliary fuel tank. This condition, if not corrected, could fail to meet fault current requirements and result in a potential ignition source that, in combination with flammable fuel vapors, could cause a fuel tank explosion and consequent loss of the airplane.
Which aircraft AD E7-10110 applies to
Whether AD E7-10110 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:
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.
