Accident Narrative
According to the pilot's report, the engine's RPM began decreasing while cruising at an altitude of 2,500 feet. When the pilot applied carburetor heat, the engine ceased running. The pilot was able to restart the engine and bring it to 1,200 rpm, but it stopped again shortly thereafter. This led to a forced landing in a soft field, during which the aircraft nosed over.
Post-Accident Examination
An inspection and operational check of the engine revealed no evidence of any pre-crash mechanical malfunction or failure.
Meteorological Conditions
The temperature was 34°F and the dew point was 24°F. According to icing probability charts, these conditions are conducive to icing in float-type carburetors during cruise flight.
