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, the tail wheel lifted off, but the airplane would not climb out of ground effect. He stated that he used all of the runway length, and did not reduce power in time to abort the takeoff. The airplane departed the runway surface into rough terrain, which resulted in substantial damage to the rudder, horizontal stabilizer, and both elevators. The pilot stated that there were no preimpact mechanical malfunctions or failures with the airplane or engine that would have precluded normal operation. He indicated that he was based at a sea level airport, and did not take into account the high density altitude (8,600 feet), which affected the airplane’s performance.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot’s delayed decision to abort the takeoff. Contributing to the accident was the pilot's inadequate preflight planning and a high density altitude, which resulted in a runway excursion and collision with terrain.
