Analysis

The airplane was damaged when it impacted the ground after takeoff from a private airstrip. In a written statement, the pilot said that the wind was light and from the northwest. He said that he elected to takeoff downwind due to obstructions north of the airstrip. He said that the airplane became airborne and flew to an altitude of about 30 to 50 feet above ground level when the airplane, "...suddenly banked hard to right. Pilot tried to correct with full left yoke deflection and slightly nose down elevator. Right wing contacted [the] ground...." A weather reporting station located about 26 miles and 200 degrees from the accident site recorded the wind as 9 knots from 340 degrees at 1053. A postaccident examination of the airplane revealed no anomalies that could be associated with a pre-impact condition.
