Flight and Power Loss
A pilot was conducting a solo training flight, practicing airwork, when a partial loss of engine power occurred. The pilot applied carburetor heat, which temporarily restored power before it decreased again. Unable to maintain adequate power, the pilot selected a field for a forced landing.
Forced Landing and Nose-Over
The selected field had a steep slope. During the landing, the nose gear contacted the terrain first, causing the airplane to nose over.
Post-Accident Examination
Following the accident, tests were conducted on the carburetor heat system, which operated normally. No other mechanical anomalies were reported in the source.
Environmental Conditions
At the time of the accident, the temperature was 31 degrees Fahrenheit and the dew point was 22 degrees Fahrenheit. According to carburetor ice probability charts, these conditions were conducive to carburetor ice formation during glide power settings.
