Takeoff With Control Lock Engaged Leads to Runway Overrun and Water Impact

Accident Narrative

The pilot conducted a takeoff with the airplane at near maximum gross weight. He reported being rushed before the flight and not following the preflight checklist. During the takeoff roll, he observed that acceleration was slower than expected, but the airspeed was sufficient for rotation. When he applied elevator back pressure to rotate, he immediately realized that the control lock was still in place on the yoke. He attempted to remove the lock but was unsuccessful. The pilot stated that he does not recall aborting the takeoff or reducing power. The airplane overran the runway end, impacted water, and came to rest inverted before sinking.

Damage

The accident caused substantial damage to the fuselage and empennage of the airplane.

Pilot Report

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
