According to the pilot the airplane touched down on the first 20 percent of a 3,000-foot runway, rolled about 1,000 feet, at 20 knots of ground speed, and began to drift to the right. The pilot attempted to correct the situation by applying full left rudder and braking, however he could not correct the right turn. The airplane turned about 120 degrees before the right main landing gear dropped into a ditch, and the left wing made contact with a gravel road. The pilot estimated that at the time of the accident "the cross wind component was "8 knots."
