Read the full NTSB narrative

After an aerial application flight, the pilot initiated a turn back toward the airstrip. The airplane's engine started to run rough and lose power. The pilot turned the airplane into the wind and initiated a forced landing into a deeply furrowed field. As the airplane touched down the landing gear sunk into the soft ground and the airplane nosed over, coming to a rest inverted. Postaccident examination of the airframe and an engine test run revealed no anomalies. The nearest weather reporting station reported a temperature of 9 degrees Celsius (C) and a dew point of 7 degrees C at the time of the accident. Review of the carburetor icing probability chart revealed that this temperature and dew point were conducive to serious icing at cruise power.
