Airworthiness Directives; McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F, DC-10-30F (KC-10A and KDC-10), DC-10-40, and DC-10-40F Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas airplanes, that requires a one- time inspection for damage of the power feeder cables and surrounding structure, and repair if necessary. For certain airplanes, this amendment requires fabricating and installing a power feeder support bracket assembly and clamps at station Y=595.000, left side. For certain other airplanes, this amendment requires installing two power feeder support brackets and clamps at station Y=606.000, left side. This action is necessary to prevent chafing of the external ground power feeder cables against the adjacent structure, which could result in arcing and fire. This action is intended to address the identified unsafe condition.
