Analysis

The pilot said he made a smooth touchdown about halfway down runway 21 (2,350 X 100) at the O'Neal Airport, Vincennes, Indiana. The pilot said that shortly after touchdown, the airplane hit a rough spot on the runway. The airplane bounced into the air, and the tail began to shift around. The pilot said that he couldn't get on the brakes because he was busy trying to keep the airplane straight. The airplane veered to the right and departed the runway into a wheat field. The plane slowed, but suddenly stopped and nosed over slowly on to its back. Examination of the airplane revealed no anomalies.
