Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident
The airplane veered off the runway after landing and nosed over. After touchdown, the airplane's nose landing gear began to shimmy with increasing magnitude. The pilot attempted to correct by applying elevator backpressure and raising the nose of the airplane. When the nose landing gear touched down on the runway again, the shimmy was worse than before. The pilot said the nose bounced back into the air and his forward visibility became impaired by the nose high attitude of the airplane. The pilot reported that he then experienced a loss of directional control. The airplane veered off the runway, nosed over, and came to rest inverted. The pilot reported no preimpact mechanical malfunctions or failures with the airplane. The free castering nose wheel and the landing gear strut assembly was examined by a Federal Aviation Administration airworthiness inspector, with no discrepancies noted.
NTSB Probable Cause Narrative
the pilot's failure to maintain directional control of the airplane during the landing rollout.
