What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) This Kitfox was built by the owner/pilot. The aircraft received a special airworthiness certificate on April 24, 2004, in the experimental amateur-built category. It had been operated 10.1 hours since it was built. During takeoff the elevator control became stuck in position, the control could not be moved forward or aft. The aircraft went to a nose high attitude and the pilot used the trim tab to gain control of the aircraft. The aircraft landed hard on the remaining runway. The nose gear was torn off and the lower structure of the aircraft was bent, broken and crushed. During a post accident investigation, a bolt was found lying in the bottom of the aircraft's hull. By matching the bolt with other bolts in the control system, it was determined that this bolt had fallen out of the elevator control pushrod-rod end bolt hole. This bolt attached to a bell crank that was attached to a pushrod assembly that moved the elevator up and down. It could not be determined if the nut was ever on the bolt or if it had not been properly installed during the assembly process.
