## Discrepancy

DURING CRUISE FLIGHT, ABOUT 5 MINUTES FROM DESTINATION THE ENGINE CONTROL SWITCH TO THE NR 1 ENGINE WAS EITHER BUMPED OR IT SLIPPED ON ITS OWN TO THE IDLE POSITION. THE PILOT HAD THE MASTER CAUTION FOR THE ENG GOING TO IDLE AND GOT A LT YAW AS WELL. THE PILOT ADJUSTED TO COLLECTIVE THE TORQUE FOR THE NR 2 ENGINE WAS IN LIMITS--BELOW 86 PERCENT. THE PILOT PUT THE SWITCH BACK TO THE "FLIGHT' POSITION AND THE TORQUES MATCHED UP IN ABOUT 10 SECONDS.  THE PILOT DIDN'T DECLARE AN EMERGENCY AND ACTUALLY LANDED AT THE INTENDED SCENE.
