Factual narrative

THE PILOT HAD BEEN FLYING FOR ABOUT 1 HOUR IN THE LOCAL AREA AND WAS RETURNING FROM THE PRACTICE AREA AT 1100 FEET AGL. IN PREPARATION FOR LANDING HE ADVANCED THE MIXTURE TO FULL RICH AND THE ENGINE LOST POWER. HE TRIED EMERG PROCEDURES BUT THE ENGINE DID NOT RESPOND. THE PILOT STATED THAT HE MOVED THE THROTTLE AND THE MIXTURE BACK AND FORTH AND SWITCHED FUEL TANKS, BUT THE ENGINE DID NOT RESPOND. HE MADE A LEFT TURN AND LANDED IN A CORNFIELD. THE OWNER OF THE ACFT EXAMINED THE ENGINE BUT DID NOT FIND EVIDENCE TO EXPLAIN THE REPORTED ENGINE FAILURE. AT THE TIME OF THE ACCIDENT THE SURFACE TEMP WAS 78F AND THE DEW POINT WAS 63F. ACCORDING TO THE CARBURATOR ICING PROBABILITY CHART, THAT COMBINATION OF TEMP/DEW POINT IS CONDUCIVE TO MODERATE CARBURETOR ICING AT CRUISE POWER AND SERIOUS ICING AT DESCENT POWER. THE PILOT SAID HE HAD NOT USED CARBURETOR HEAT DURING THE FLIGHT. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
