The aircraft then entered a steep climb at the end of the runway, reaching an altitude of 200 to 300 feet above ground level. It subsequently turned left onto a crosswind leg of the traffic pattern. During the turn, the left wing dropped into a steep bank and the nose dropped.
The aircraft impacted a wheat field in a wings-level, slightly nose-down attitude with a high sink rate. After the principal impact, the aircraft slid 66 feet.
