The NTSB's narrative final · quoted from the NTSB record
The purpose of the flight was for the student pilot to perform a solo cross-country and land at the accident airport. The student pilot stated that following a stabilized approach, he did not properly maneuver the airplane into a flare. The airplane touched down hard on the runway surface and bounced back into the air. The airplane then touched down again and then bounced multiple times, porpoising along the runway. As a result of the impact, the airplane incurred damage to the firewall. The student pilot noted that he failed to add engine power to correct the self-induced oscillation. He stated that there were no pre-impact mechanical malfunctions or failures that would have precluded normal operation.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number WPR25LA243.
