## Discrepancy

ENG1 ON APPROACH FLAME OUT. PROCEEDED BY QRH -  AFTER TROUBLESHOOTING, 5 TRIPS TO THE BLAST FENCE FOR GROUND HIGH POWER RUNS, AND 2 FCF’S TO CHECK THE TORQUE PROBLEM. WE REPLACED THE TORQUE SENSOR AND SWAPPED ALTERNATORS FOR TROUBLESHOOTING WITH NO HELP. THE LAST THING TO CHANGE WAS THE ECU AND THAT WAS ACCOMPLISHED. COMPLETED HIGH POWER GROUND RUNS AND RELEASED THE AIRCRAFT. THERE HAS NOT BEEN A REPEAT WRITE-UP SINCE THE ECU WAS CHANGED.
