Aircraft: Cessna 172. Injuries: 1 Minor. Location: Culebra, P.R. Aircraft damage: Substantial.
What reportedly happened: After doing an engine runup, the pilot taxied onto the runway and started his takeoff roll. During the attempted takeoff, he realized that the control wheel would not move aft when he tried to pull back on it because the flight control lock was still installed.
He tried to remove the control lock while the airplane was on the go, but was not successful. The airplane was approaching the airport perimeter fence so he aborted the takeoff. The airplane crashed through the fence, crossed a road, and into trees.
Checklist procedures for the airplane require that the control wheel lock be removed during the preflight inspection, and that the flight controls be checked prior to takeoff to ensure free and correct operation before takeoff. During a post-accident interview, the pilot stated that he did not use the checklist.
Probable cause: The pilot’s failure to remove the flight control lock before takeoff.
