Analysis

According to the pilot, he was landing on runway 8 when the airplane encountered a gust of wind. The pilot corrected for the gust of wind and the airplane became airborne again. When the airplane touched down again, the airplane began to rotate to the left. The right main landing gear collapsed and the right wing impacted the ground, resulting in substantial damage to the right wing spar. The pilot stated that there were no mechanical anomalies with the airplane at the time of the accident. An examination of the airplane and its related systems, conducted by a Federal Aviation Administration Inspector, revealed no anomalies.
