Accident Overview
A student pilot and a certified flight instructor (CFI) were conducting landing practice. After completing three touch-and-go landings, the engine lost power at about 200 feet above ground level during the fourth takeoff. The CFI reported turning the aircraft approximately 25 degrees in an attempt to glide to a bean field and avoid tall corn. However, there was insufficient altitude to clear the corn. The aircraft landed in a corn field on muddy ground and nosed over.
Post-Accident Examination
An examination of the engine and aircraft revealed no preimpact mechanical problem that would have resulted in a loss of power. The engine was started and run to 1,500 RPM with no problems noted, except that it could not be operated at a higher RPM due to a bent propeller.
Weather Conditions
The temperature and dew point were 78°F and 77°F, respectively. According to icing probability charts, serious carburetor icing conditions would have existed at idle power. The CFI stated that they had used carburetor heat on the downwind leg of each pattern, then placed it in the cold position for each takeoff.
