DC-lO-40F, MD-IO-IOF, MD-IO-30F, MD-ll, and MD-lIF Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed mlemaking (NPRM).

SUMMARY: We propose to adopt a new airworthineSSldirective (AD) for certain Mo

DC-IO-IO, DC-IO-IOF, DC-IO-15, DC-IO-30, DC-lO-30F (KC-IOA and KDC-IO),

DC-l0-40, DC-IO-40F, MD-IO-IOF, MD-lO-30F, MD-Il, and MD-IlF airplanes. Thi

proposed AD would require 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

proposed AD would also require installing an in-line fuse in certain fuel pump pressure

switches. This proposed AD results from fuel system re iews conducted by the

manufacturer. We are proposing this AD to prevent fuel tank explosions and conseque

loss of the airplane.

DATES: We must receive comments on this proposed AD by [INSERT DATE 45

DAYS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER].
