HE HAD ABOUT 4 HOURS IN THE C-172 AND HAD JUST CHECKED OUT IN IT. THE PLT HAD TAKEN HIS BROTHER AND A FRIEND FOR A RIDE IN THE LOCAL AREA FOR ABOUT AN HOUR. UPON RETURNING TO THE FIELD, HE MADE A TRAFFIC PATTERN AND DURING THE TURN FROM DOWN WIND TO BASE TRIED TO ADD POWER TO CORRECT FOR LOW ALTITUDE. THE ENGINE DID NOT RESPOND. HE LANDED IN A PLOWED GARDEN AND THE AIRPLANE NOSED OVER. SUBSEQUENTLY, THE ENGINE WAS INSPECTED AND A RUN PERFORMED. IT OPERATED SATISFACTORILY. ATMOSPHERIC CONDITIONS WERE FAVORABLE FOR THE FORMATION OF CARBURETOR ICE. THE CARBURETOR HEAT CONTROL WAS FOUND IN THE COLD POSITION.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: CARBURETOR ICE DUE TO THE FAILURE OF THE PILOT TO PROPERLY USE THE CARBURETOR HEAT CONTROL DURING DESCENT AND FLIGHT IN THE TRAFFIC PATTERNS AT REDUCED POWER. UNDERLYING THIS IS INADEQUATE TRAINING IN THE PROPER UNDERSTANDING OF CARBURETOR ICING AND THE PROPER METHODOLOGY OF DEALING WITH THIS PHENOMENON.
