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 reported that he landed on runway 10, and during the roll out the airplane veered to the left, and impacted with a ditch. He stated that on the downwind leg he completed a landing check, and he believed the yaw damper was "disengaged," but did not physically check to see that it was disengaged. He said just before touchdown he felt lateral directional movement, and the nose "kicked left a few degrees." He attempted to steer the airplane back to the center of the runway, but the rudder was "locked." He then realized that he did not disengage the yaw damper and attempt to correct the airplane's directional control was unsuccessful. At this point the airplane was partially off the runway and finally departed the left side of the runway. The airplane traveled through some tall weeds, and "dropped into a ditch. In addition, the pilot said he had landed with a crosswind from the left.

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

the pilot's failure to maintain directional control during the landing roll, which resulted in the airplane departing the left side of the runway, and impacting with a ditch. Factors in this accident were; the pilot did not follow the procedures, and deactivate the yaw damper.
