The NTSB's narrative final · quoted from the NTSB record
WHILE RETURNING FROM A SUPERVISED SOLO TRAINING FLIGHT, THE AIRCRAFT ENGINE LOST POWER. AFTER AN UNSUCCESSFUL RESTART ATTEMPT, INCLUDING APPLICATION OF CARBURETOR HEAT, THE STUDENT PILOT ELECTED TO CONTINUE THE APPROACH TO THE DESTINATION AIRPORT, WHICH WAS APPROXIMATELY 3 MILES AHEAD. THE AIRPLANE LANDED IN A GRASSY AREA ADJACENT TO THE RUNWAY AND NOSED OVER. POST ACCIDENT EXAMINATION OF THE ENGINE FAILED TO REVEAL ANY EVIDENCE OF MECHANICAL MALFUNCTION OR FUEL STARVATION. DURING THE ENGINE EXAMINATION, THE TOPS OF THE PISTONS APPEARED TO HAVE BEEN STEAM CLEANED DURING COMBUSTION. THE ENGINE WAS RUN ON THE AIRFRAME AND OPERATED NORMALLY. WEATHER CONDITIONS AT THE TIME OF THE ACCIDENT WERE FAVORABLE FOR THE FORMATION OF CARBURETOR ICE. AT NO TIME DURING THE FLIGHT DID THE PILOT REPORT USING THE CARBURETOR HEAT BEFORE THE ENGINE QUIT.
