Although his touchdown was uneventful, he reported that, during the landing roll, he lost control of the airplane when he encountered a crosswind of about 10 knots. After the pilot lost control, the airplane ground looped, and the left wing struck the runway with sufficient force to bend the wing spars. The pilot reported that there were no mechanical anomalies or malfunctions of the airplane's directional control system. ## Factual narrative The pilot, who was flying a tailwheel-equipped airplane, was performing a full-stop landing on a paved runway.
