Probable cause
The pilot not maintaining directional control during the takeoff roll. Contributing to the accident was the rough condition of the airstrip.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot stated that the airstrip was rough and during the takeoff roll the airplane hit a hump and became airborne earlier than he expected. He stated he had too much right rudder applied and the airplane veered off the side of the runway and struck some vegetation and nosed over.
