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 reported that, during the takeoff roll on a dirt airstrip, the tailwheel-equipped airplane veered to the right. He added that he “could not see [the] right edge of [the] strip due to [the] tail being low and [the] contour of [the] terrain descending away”; therefore, “corrective measures were not applied.” Subsequently, the airplane veered off the right side of the runway, impacted small shrubs/trees and a large rock, and then came to rest inverted. 
The airplane sustained substantial damage to both wings and the empennage.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane 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 takeoff roll.
