Analysis

At the beginning of a local pleasure flight, the pilot lost control of the aircraft while practicing high speed taxiing for directional control for takeoffs and landings. Upon reaching liftoff speed, the power was reduced to idle. The aircraft swerved to the left and right rudder was applied. The aircraft then swerved to the right and full left rudder and forward stick were applied. Subsequently, the left wing struck the ground and the aircraft nosed down.
