Incident Summary
A pilot conducting a taxi run to evaluate an airplane's performance at taxi speeds reported that the vehicle unexpectedly became airborne while traveling down the runway. The event occurred when the airplane was approximately halfway along the runway length. After becoming airborne, the airplane lurched to the left.
Pilot's Actions
In response to the unintended flight, the pilot reduced the throttle, cut the mixture control, and turned the fuel selector valve to the off position. These actions were taken to terminate the uncommanded ascent and control the airplane's trajectory.
Outcome and Damage
The airplane subsequently made contact with the ground and slid to a stop. The impact and slide resulted in damage to the left wing, landing gear, propeller, engine mounts, and windshield. The pilot did not specify any other damage or injuries. No further details about the airplane's configuration, location, or environmental conditions were provided in the source.
