Analysis

According to the pilot of the tailwheel-equipped airplane, he made an approach to a dirt runway. The pilot reported that the airplane bounced during the touch down, and when it settled back to the runway the airplane's heading was not aligned with the runway heading. He recalled the airplane ground looped to the right, the left main landing gear collapsed, and the left wing struck the ground. The left wing ribs and aileron sustained substantial damage. The pilot reported that there were no mechanical malfunctions or anomalies with any portion of the airplane that would have prevented normal flight operations.
