Vans RV8 — Mandan, ND

What happened

While the airplane was parked on the ramp before the flight, a witness noted that the aft cockpit seatbelt was wrapped around the control stick to secure the flight control surfaces; the conditions at the airport at the time were described by a second witness as "very windy." The first witness reminded the pilot to remove the belt before departure. Both witnesses noted that the airplane's elevator was up as the airplane taxied out for departure. The airplane's takeoff ground roll was short, and as the airplane became airborne, it entered a steep climb to about 50 ft above the ground, rolled left, then entered a vertical descent to ground contact. The witnesses noted that the airplane's elevator was in the full up position at the accident site and as the fire continued, the elevator slowly lowered.

Postaccident examination of the wreckage did not reveal any preimpact anomalies that would have precluded normal operation of the airplane. The seat belt webbing was not identified in the charred cockpit. Given the available information, it is likely that the pilot, seated in the front cockpit of the tandem-configured airplane, failed to remove the seat belt from the aft control stick before departure, resulting in a loss of control during the initial climb and subsequent impact with terrain. The elevator likely lowered as the webbing material melted due to the fire.
