## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas DC-10-30 and DC-10-30F airplanes. This AD requires installing Teflon sleeving around the fuel pump wire harness inside the conduit in the aft supplemental fuel tank. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
