## Discrepancy

DURING CRUISE FLIGHT LEFT ENGINE THROTTLE STUCK AT 95% N2 WITH NO ABILITY TO ADJUST. LEFT ENGINE THROTTLE CUTOFF ALSO LOCKED IN ON POSITION. PILOTS WERE ABLE TO FREE THE ENGINE CONTROL AND MANIPULATE POWER AS REQUIRED. UPON INSPECTION OF THE AIRCRAFT AT KMDT IT WAS NOTED THAT THE LEFT ENGINE THROTTLE CONTROL WAS NOTCHY/STIFF. WE WERE ABLE TO CLEAN THE FRICTION CONTROL SUBASSEMBLY AND THE LEFT THROTTLE RETURNED TO SMOOTH OPERATION.
