The National Transportation Safety Board determined the probable cause of this incident to be: The pilot's delayed application of carburetor heat while operating in conditions conducive to carburetor icing.
The pilot reported that the airplane's engine began to run rough during level flight with about a 70 percent power setting. He switched fuel tanks and applied carburetor heat, but the airplane's engine continued to run rough. The pilot initiated a forced landing to a cornfield during night light conditions. Postaccident examinations of the airplane revealed that the firewall was bent/buckled. No anomalies were found with regard to the airplane, engine, or systems during the postaccident examinations. A weather report for the destination airport recorded the temperature and dew point as 18 degrees Celsius and 16 degrees Celsius respectively.

Analysis
The pilot reported that the airplane's engine began to run rough during level flight with about a 70 percent power setting. He switched fuel tanks and applied carburetor heat, but the airplane's engine continued to run rough. The pilot initiated a forced landing to a cornfield during night light conditions. Postaccident examinations of the airplane revealed that the firewall was bent/buckled. No anomalies were found with regard to the airplane, engine, or systems during the postaccident examinations. A weather report for the destination airport recorded the temperature and dew point as 18 degrees Celsius and 16 degrees Celsius respectively. According to a Federal Aviation Administration Special Airworthiness Information Bulletin, entitled Carburetor Icing Prevention, the temperature and dew point were conducive to the formation of carburetor icing.
