## Discrepancy

AT LIFT OFF ON TAKEOFF, THE FOLLOWING OCCURRED.  FCP WENT BLANK.  ATS LEVER TRIPPED OFF.  INSTRUMENTATION ON BOTH SIDES DISAPPEARED, EXCEPT FOR ADI'S & SPEED SCALES.  FMS ON BOTH SIDES WENT TO INDEPENDENT OPERATIONS, FCP INTERMITTENTLY RE-ILLUMINATED, BUT SETTINGS FLUCTUATED & FCP WOULD AGAIN GO BLANK.  MAINTAINED VMC & RETURNED, TOTAL TIME AIRBORNE, 10 MINUTES.  FOUND THE GEN 1 9XU LINE CONTACTOR OVERHEATED, ALL OTHERS WERE COOL.  REMOVED AND REPLACED THE 9XU GEN 1 LINE CONTACTOR USING THE A300-600 AMM REF 24-22-15-04.
