Summary
We are adopting a new airworthiness directive (AD) for all McDonnell Douglas airplanes identified above. This AD requires revising the airplane flight manual to provide the flightcrew with procedures to preclude dry running of the fuel pumps. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent pump inlet friction (i.e., overheating or sparking) when the fuel pumps are continually run as the center wing fuel tank becomes empty, and/or electrical arc burnthrough, which could result in a fuel tank fire or explosion.
