This AD results from reports of failures of the fuel pump housing electrical connector having P/N 60-84355-1. The Federal Aviation Administration is issuing this AD to detect and correct insulation resistance degradation and arcing in the potted backside of the electrical connector assembly of the fuel boost/transfer pump housing, which could compromise its performance and cause an ignition source in the fuel tank, resulting in a fuel tank explosion and consequent loss of the airplane.
