The pilot departed on a local flight. According to radar data, the airplane headed south and climbed to 4,500 ft mean sea level (msl). After about 20 minutes, the airplane turned back to the north and began a 500 ft per minute descent. The airplane turned to the east and then to the southeast. The last radar return showed the airplane at 1,700 ft msl (about 700 ft above ground level), on a heading of 143°, and flying at 96 knots. The airplane continued to descend and turn and collided with a corn field on a heading of 45°. The pilot had no recollection of the accident. Impact and fire damage precluded a functional examination of the airframe and flight controls. A postaccident examination of the engine revealed no anomalies. Investigators were unable to determine the cause of the accident with the available information.
