## Discrepancy

LEFT AFT BOOST PUMP CONNECTOR BURNED TO PUMP ASSEMBLY.  THE LEAKAGE OBSERVED WAS VERIFIED AND CAUSED BY  A LOCALIZED OVERHEATING  OF THE CONNECTOR PINS THAT  RESULTED IN DAMAGE TO THE SEAL AROUND PIN 2. THE CAUSE FOR THE EXCESSIVE OVERHEATING IN THE CONNECTOR PIN AREA IS UNKNOWN. REPLACED FUEL BOOST PUMP. DEFECTIVE PUMP WAS MADE SERVICABLE.
