## Discrepancy

THE PILOT WHILE IN FLIGHT FELT A YAW MOVEMENT FROM THE ACFT FOLLOWED BY A INCREASE OF ENGINE TORQUE AND MAIN ROTOR SPEED.  THE PILOT THEN REDUCED THE FUEL TO THE ENGINE WITH THE ENGINE FUEL CONTROL LEVER AND CONDUCTED A PRECAUTIONARY LANDING IN A LOGGING ROAD.  AFTER THE ENGINE SHUTDOWN THE PILOT DID A VISUAL INSP OF THE ACFT AND FOUND 1 OF THE ENGINE CAPACITY DAMPER BROKEN ON THE ENGINE DECK.  A MECHANIC WAS THEN DISPATCH TO THE SITE AND THE PART WAS REPLACED.  ENGINE GROUND RUN AND LEAK CHECK WAS CARRIED-OUT AND NO OTHER PROBLEM WAS FOUND.  THE ACFT WAS THEN RELEASED FOR SERVICE.
