Landing and Runway Excursion
According to the pilot, the landing on runway 21 at O'Neal Airport in Vincennes, Indiana, was smooth and occurred about halfway down the 2,350-foot-long, 100-foot-wide runway. Shortly after touchdown, the airplane encountered a rough spot on the runway surface, causing it to bounce into the air. During the bounce, the tail began to shift, and the pilot reported being unable to apply brakes while attempting to maintain directional control.
Departure from Runway
The airplane veered to the right and departed the runway, entering a wheat field. As the airplane slowed, it came to a sudden stop and nosed over slowly onto its back.
Post-Accident Examination
An examination of the airplane revealed no anomalies or mechanical issues that could have contributed to the event.
