Analysis

On 2/16/82, the county sheriff received information that the pilot had wrecked his aircraft on 2/13/82. He went to the scene and observed the aircraft in an inverted position on snow covered terrain. On 2/20/82, he received information that the pilot had another accident. The sheriff went out again and found the aircraft on its top about 2 or 3 miles southwest of the location of the first mishap. He also noted that the pilot's tractors and one pick-up truck were located where a runway had been plowed at the location of the first mishap. A doctor that examined the pilot after the crash stated that the pilot said he had been hunting coyotes. The pilot was uncooperative in providing information concerning the accident. According to FAA records, the pilot had no valid pilot license or medical certificate. His previous license had been revoked.
