The NTSB's narrative final · quoted from the NTSB record
During cruise flight the engine lost partial power and the rpm decreased from 2,300 to 1,200. The pilot applied carburetor heat, but engine power was not restored, and the pilot made a forced landing in an open field. The nose gear collapsed during the landing. An examination of the engine revealed no evidence of internal component failure. Review of a carburetor icing probability chart disclosed that the temperature and dew point were within an area of the chart annotated "Moderate Icing -- Cruise Power or Serious Icing Descent Power."
