Summary
The FAA is adopting a new airworthiness directive (AD) for all McDonnell Douglas Model DC-8-62, DC-8-62F, DC-8-63, DC-8-63F, DC-8-72, DC-8-72F, and DC-8-73F airplanes. This AD requires deactivating certain components (the sump heater, scavenge valve, and scavenge pump) of the center wing fuel tank. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent certain conditions related to these components, which could lead to a possible ignition source in the fuel tank and a potential fire or explosion.
