Analysis

The airplane was substantially damaged when it nosed over during a forced landing following a loss of engine power. The pilot sustained minor injuries. The pilot stated that the airplane was approximately 3 miles from the intended destination when the engine abruptly quit. She recalled checking the oil pressure and temperature indications, which were both within the green arc. The pilot reported that she applied carburetor heat after the loss of engine power with no effect. She stated that the airplane was outside of power-off gliding distance to the airport and she set-up for a forced landing to a soybean field below the aircraft. The pilot landed successfully, however, she was unable to stop prior to reaching an 8-inch rise at the edge of the field. The airplane subsequently nosed over when it encountered the uneven terrain. A post accident inspection did not reveal any anomalies consistent with a loss of engine power. The engine was subsequently test run. The engine ran smoothly and no discrepancies in its operation were observed. The temperature and dew point recorded at the University of Illinois-Willard Airport (CMI), located approximately 15 miles north of the accident site, about 8 minutes after the accident, were 26 degrees and 15 degrees Celsius, respectively. Data provided by Transport Canada indicated the possibility of moderate carburetor icing at cruise power and serious icing at descent power under those conditions.
