Accident Details
Probable Cause and Findings
The pilot's failure to maintain airplane control during takeoff in high density altitude conditions, which resulted in a collision with terrain. Contributing to the accident was the pilot's failure to accomplish performance calculations for the atmospheric conditions.

Analysis
The pilot in the tailwheel-equipped airplane reported that during the takeoff roll, about two-thirds of the way down the runway at rotation speed of 70 mph, the airplane was not lifting off as normal. At 75 mph nothing was changing so the pilot attempted to place the airplane into ground effect, "something I learned to do in other types but not this plane." The pilot recalled that he added "too much forward stick" and the airplane porpoised, ascended and rolled to the right. The pilot leveled the wings, however, the airplane descended and collided with terrain. The airplane sustained substantial damage to both wings, canard, and the empennage.
The pilot reported that there were no mechanical failures or malfunctions with the airplane that would have precluded normal operation.
The pilot further reported that he did not accomplish any performance planning for the atmospheric conditions before the flight. At the time of the accident, the density altitude was calculated at 6,977ft.
