Airworthiness Directives; McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, and MD-10-30F Airplanes
This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas transport category airplanes listed above. This action requires inspecting the fuel boost/transfer pumps or reviewing the airplane maintenance records to determine the part number of the fuel boost/transfer pumps, and follow-on actions if necessary. This action is necessary to prevent heated localized temperatures within the fuel boost/transfer pumps due to frictional heating, which could result in a potential source of ignition in a fuel tank and consequent fire or explosion. This action is intended to address the identified unsafe condition.
