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

The pilot reported that while landing in a tailwind, he lost directional control on the tail wheeled airplane, and it veered to the left. Subsequently, the main gear exited the runway surface and resulted in the airplane nosing over. The airplane sustained substantial damage to the vertical stabilizer and left-wing strut. The pilot reported that there were no preaccident mechanical failures or malfunctions 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 docket at the NTSB holds the report as a PDF and the investigation's photographs and documents. This site 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 WPR24LA043.
