Analysis

During the initial part of his takeoff roll in a tailwheel-equipped airplane, the pilot lost directional control in variable and gusting winds. During his attempt to regain control, the airplane's wing impacted the runway, resulting in bending damage to the main spar of the wing. At the time of the attempted takeoff, the winds were variable at 15 to 25 knots.
