NTSB Factual Report

The pilot reported that the airplane was about 20 feet above ground level during the initial takeoff climb when a "heavy wind started." The airplane was pushed right about 30 to 40 feet, and then the right wing "went straight up." The pilot said that he took corrective action and leveled the wings. At that point, the airplane "quit flying," struck the ground, and nosed over coming to rest on its back. According to the pilot, the winds were calm when he started the takeoff, and "black clouds came in over the west mountain ridge" after he started the takeoff roll.

NTSB Probable Cause

The pilot's inadequate compensation for the gusty wind conditions and his failure to maintain aircraft control, which resulted in a loss of control and collision with terrain during the takeoff initial climb. A contributing factor was the gusty wind condition.
