NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot said that the first 700 feet of the takeoff runway was concrete and the remaining 1,600 feet was wet turf. He said that during the takeoff roll on the wet turf the left main landing gear tire encountered a 'soft rut' and the airplane yawed to the left. He indicated that his head hit the roll-bar. By the time he recovered, the airplane had slowed to the point that it impacted a ditch at the end of the runway and nosed over. The pilot did not indicate any mechanical problems with the airplane and said that the engine power remained 'full' throughout the takeoff roll.

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

the pilot's selection of unsuitable terrain for takeoff. Factors were wet and soft runway conditions, and a ditch and the end of the overrun area.
