About 10-15 feet above the ground, the airplane encountered a gust of wind that caused a roll to the right. The right wing tip collided with the ground. The pilot decreased engine power and the left wing and left gear leg collided with the ground. The pilot reported no preaccident mechanical malfunctions or anomalies that would precluded normal operation. ## Factual narrative According to the pilot, the airplane was on stabilized approach to an airstrip.
