This AD results from reports of short circuits in an electrical connector at the wing-to-body electrical disconnect panel. We are issuing this AD to prevent a short circuit of the electrical connector for the fuel boost pump, which could cause the instruments for the fuel, flap, slat, and aileron systems to malfunction and create a potential ignition source inside the fuel tank. A potential ignition source inside the fuel tank in combination with flammable fuel vapors could result in a fuel tank explosion and consequent loss of the airplane.
