NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
The pilot of the tailwheel equipped airplane reported that during the landing roll in crosswind conditions the airplane veered off the runway to the left. The pilot further reported that in order to avoid hitting a drainage ditch he "braked too hard" and subsequently the airplane nosed over.
The airplane sustained substantial damage to the firewall.
According to the pilot there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's failure to maintain directional control during the landing roll, which resulted in a runway excursion, and a nose over.
