## Discrepancy

(CAN) DURING LAST OPERATIONS BEFORE LANDING THE PILOT REPORTED THAT NR 1 ENGINE TORQUE INDICATION WAS DECREASING WHILE NR 2 ENGINE TORQUE WAS INCREASING.  ITT THEN SUDDENLY DASHED OUT.  THE PILOT ELECTED TO ABORT LANDING AND RETURNED TO POINT OF ORIGIN.  ITT CAME BACK ON, BUT WAS FLUCTUATING.  DURING RETURN TO BASE ITT WAS REPORTED GOING FROM 0 TO 1500 DEG AND DASHING OUT AGAIN.  THE ACFT SAFELY LANDED BACK TO POINT OF DEPARTURE.
