Accident Sequence
The single-engine airplane impacted a vertical bluff while maneuvering shortly after takeoff from a 3,200-foot grass runway. The flight instructor, a private pilot, and a student had flown to the airport, ate dinner, and departed just before nightfall because the runway did not utilize runway lights.
Witness Reports
Numerous witnesses reported that the airplane did not accelerate normally during the takeoff roll, requiring nearly the entire turf runway to become airborne. They then described a slow, nose-high climb. The airplane flew east along a river before turning left prior to encountering power lines. The airplane then impacted the bluff and erupted in flames.
Post-Accident Findings
A post-accident examination of the airplane and engine revealed no anomalies that would have prevented their normal operation. The flap handle was found selected to 25 degrees. People familiar with the airport indicated that the best way to depart the airport area was to fly along a valley that veered toward the northeast instead of flying along the river as the accident flight did. The river is in line with steep bluffs and is crossed by power lines.
