NTSB Factual Report

The pilot reported that during the takeoff roll, he tried to abort the takeoff because he had not removed the bolt he had placed in the yoke for a gust lock. He reported that the crosswind pushed the airplane off the right side of the runway into the grass, the airplane impacted trees, and sustained substantial damage to both wings and the empennage. The pilot reported that the accident was due to him not removing the bolt in the yoke.

The pilot reported no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

NTSB Probable Cause

The pilot's failure to remove the gust lock during the preflight inspection, resulting in a loss of control and collision with trees during takeoff.
