Probable cause

A loss of control during the initial climb for undetermined reasons, which resulted in an aborted takeoff and runway excursion.

NTSB narrative

The pilot was departing on a local flight to test a repaired autopilot. Just after takeoff, the airplane began to yaw to the left and right, and the pilot determined that directional control was not possible. The pilot decided to abort the takeoff, reduced the power to idle, and landed gear-up on the remaining runway. The airplane slid off the end of the runway onto a concrete pad, resulting in substantial damage to the left wing. Examination of the flight controls and throttle quadrant controls did not reveal any anomalies. The reason for the yaw and loss of directional control after takeoff could not be determined.

Analysis
