The NTSB's narrative final · quoted from the NTSB record

The pilot reported that, during the landing the airplane touched down about halfway down the runway. He applied heavy braking when he noticed the runway end was approaching. The airplane subsequently overran the runway end and collided with a fence. The right wing was substantially damaged. The pilot initially reported that the brake system did not function as expected; however, a brake system examination did not reveal any preaccident mechanical failures or malfunctions that would have precluded normal operation. The pilot later stated that the airspeed was likely too fast when he touched down, which resulted in a runway overrun.

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 WPR22LA356.
