During takeoff roll, a pilot found the control wheel locked, attempted to remove it but failed, then shut down the engine and used elevator trim, but the airplane struck a fence and trees, resulting in substantial damage.

Takeoff Attempt with Control Lock Installed

A pilot completed an engine runup and taxied onto the runway, initiating a takeoff roll. At approximately 60 knots indicated airspeed, the pilot attempted to rotate for takeoff but found that the control wheel would not move when pulled back. The pilot then noticed that the flight control lock was still installed and attempted to remove it, but it would not come out.

Aborted Takeoff and Collision

Realizing that the airplane was approaching the airport perimeter fence, the pilot shut down the engine and tried to use the elevator trim to raise the nose. The airplane subsequently impacted the fence, bounced off a road, and struck trees. A post-accident examination revealed that the wings and fuselage sustained substantial damage.

Checklist Procedures Not Used

According to the airplane's checklist procedures, the control wheel lock must be removed during the preflight inspection, and the flight controls must be checked prior to takeoff to ensure they are free and correct. However, during a post-accident interview, the pilot stated that he did not use the checklist.
