## Analysis

The pilot reported that during landing, after touchdown and rolling about 40 to 50 feet, the airplane suddenly veered to the left. He said that he was unable to correct before the left wing struck the corn along the runway. The airplane spun about 180 degrees. During the encounter, the right main landing gear broke about half way between the wheel and the intersection of the landing gear and fuselage. Examination of the airplane after the accident revealed damage to both wings including damage to underlying ribs, the right landing gear, and the lower portion of the rudder. Control system continuity was established and no preimpact defects were found. Examination of the grass runway revealed no defects in the runway surface.
