## Analysis

THE AIRCRAFT LOST POWER DURING DESCENT AND CRASHED INTO TREES. THE WEATHER WAS VMC AND NO FLIGHT PLAN WAS FILED. THE PILOT SAID HE WAS DESCENDING WITH REDUCED POWER AND WHEN HE TURNED CARBURETOR HEAT ON THE ENGINE BEGAN TO MISS SO HE TURNED CARBURETOR HEAT OFF. AT THIS TIME HIS ALTITUDE WAS LOW SO HE TURNED AND LANDED UPHILL. THE ONLY DISCREPANCY FOUND IN THE POWERPLANT WAS DEBRIS IN THE CARBURETOR WHICH PLUGGED THE INTERNAL PASSAGES AND SIMULATED CARBURETOR ICE.
