## Discrepancy

DURING TAKEOFF, THE LT HAND ENGINE WAS ONLY PRODUCING 85 PERCENT TORQUE AND THE CREW ABORTED TAKEOFF.  THE AIRCRAFT WAS THEN FERRIED TO DAY.  MAINTENANCE INSPECTED AND REPLACED THE LEFT HAND TORQUE SIGNAL CONDITIONER AND LEFT HAND TORQUE PROBE IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 73-00-00.  POWER ASSURANCE RUNS WERE PERFORMED AND NO DEFECTS WERE NOTED.  THE AIRCRAT WAS THEN RELEASED FOR SERVICE.
