Airworthiness Directive E7-17829
one-timeAirworthiness Directives; McDonnell Douglas Model MD-11, MD-11F, DC-10-30 and DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, and MD-10-30F Airplanes
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model MD-11, MD-11F, DC-10-30 and DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, and MD-10-30F airplanes. This AD requires measuring the electrical resistance of the bond between the No. 2 fuel transfer pump adapter surface of the fuel tank and the fuel transfer pump housing flange, and performing corrective and other specified actions as applicable. This AD results from a design review of the fuel tank systems. We are issuing this AD to prevent inadequate bonding between the No. 2 fuel transfer pump adapter surface of the fuel tank and the fuel transfer pump housing flange. Inadequate bonding could result in a potential ignition source inside the fuel tank if the fuel transfer pump and structure interface are not submerged in fuel, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Which aircraft AD E7-17829 applies to
Whether AD E7-17829 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.
