The single engine airplane impacted a vertical rock cliff face in mountainous terrain about 500 feet below a mountain ridge line. Global Positioning System (GPS) data was recovered from a portable GPS unit that was located with the airplane wreckage. The GPS data track originated in the vicinity of the departure airport, and proceeded at 8,350 feet mean sea level (msl) northeast for 57 miles, and abruptly ends in the vicinity of the accident site. During the last 2 minutes of the flight, the track increased in altitude from 8,350 feet to 8,891 feet msl. The height of the mountain ridge line directly ahead of the airplanes' flight path was between 9,100 feet and 9,580 feet msl. The end of the GPS track did not exhibit any deviations that could be interpreted as an evasive maneuver.
