We are adopting a new airworthiness directive (AD) for 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, DC-10-40F, MD-10-10F, MD-10-30F, MD-11, and MD-11F airplanes. This AD requires installing an in-line fuse in certain float level switches and sleeving the wires between the fuel tank and the in- line fuse. For certain airplanes, this AD also requires installing an in-line fuse in certain fuel pump pressure switches. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent fuel tank explosions and consequent loss of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 60 months after the effective date of this AD do the actions specified in paragraph (g)(1) or (g)(2) of this AD, as applicable.
