The pilot was landing on a 900 foot landing strip located on his private ranch and overshot the runway. The aircraft collided with a new hangar under construction, then impacted a tractor, destroying the aircraft. According to the pilot's logbook, the last dual instruction flight and instructor solo signoff the student received was on September 26, 1996, 20 months prior the accident.

The student pilot's failure to select a proper touchdown point. A factor was his lack of recent experience conducting solo flight operations.
