Probable cause
The pilot's failure to maintain directional control during takeoff, resulting in a runway excursion and collision with terrain.
NTSB analysis
The pilot reported that during the takeoff roll, the airplane rolled over a bump on the runway surface and became airborne. The airplane descended to the runway while operating at takeoff power, resulting in a departure end runway excursion and collided with terrain. The airplane sustained substantial damage to the wings, fuselage and rudder.
The pilot reported that there were no mechanical malfunctions or failures with the airplane prior to the flight that would have precluded normal operation.
