The NTSB's narrative final · quoted from the NTSB record
The pilot reported that following an uneventful landing in a tailwheel-equipped airplane, in light and variable wind conditions, the airplane suddenly pulled hard to the right. Despite his control inputs, the airplane ground looped. Subsequently, the left main landing gear collapsed, which resulted in substantial damage to the left wing. The pilot reported no mechanical malfunctions or failures with the airplane 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 WPR11CA396.
