Analysis

The 40,000-hour airline transport rated pilot attempted to takeoff with the control gust lock installed. He stated to an FAA inspector on-scene that he had forgot to remove the gust lock. He also reported to his insurance company that he failed to remove the control lock well into the takeoff roll. He stated that he reduced the throttle and went over the airport fence and landed on a road. The pilot filed a partial Aircraft Accident Report without a statement.
