The airplane departed the runway surface at a 90-degree angle, and the right wing sustained substantial damage when it contacted the terrain. The airplane made a 360-degree turn in the grass before it returned to the runway. The pilot reported the airplane had a tendency to swerve on the ground, especially on hot days with little to no wind. The wind at the time of the accident was reported as calm. The pilot reported that there was no mechanical failure or malfunction of the airplane that would have resulted in the loss of control. ## Factual narrative The pilot was practicing takeoffs and landings when the accident occurred.
