On August 31, 2008, about 0830 central daylight time, a Fantasy Air SRO, Allegro 2000, N1005W, piloted by a student pilot, sustained substantial damage during landing. The airplane impacted corn after departing the runway at the Big Foot Airfield, Walworth, Wisconsin. The personal 14 CFR Part 91 flight was operated in visual meteorological conditions without a flight plan. The pilot was not injured. The flight originated from the Dupage Airport, West Chicago, Illinois about 0800. 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.
