Confidence Rating: Accident investigation report completed and information captured
The pilot encountered a partial loss of engine power during flight. The use of carburetor heat did not regain the lost power. The pilot performed a precautionary landing to a grass landing strip he had landed at before. The airplane nosed over in the snow upon landing. No pre-impact anomalies were detected. The local temperature and dew point was -2 degrees C and -9 degrees C respectively. The owner's recommendation was to "replace the metal tube with scat tube on carb heat side."

Probable Cause: The partial loss of engine power for undetermined reasons during cruise and the unsuitable terrain encountered during the precautionary landing. A factor was the snow-covered ground.
