The NTSB's narrative final · quoted from the NTSB record
The pilot reported that during a go-around, the right-wing leading-edge slat retracted to the stowed position, and the airplane rolled to the right. The pilot attempted to correct with opposite aileron; however, the airplane continued the right roll and impacted the ground. The airplane sustained substantial damage to both wings, fuselage, and the empennage. According to the airplane kit manufacturer, the wing leading-edge slats are self-deploying and self-stowing. The pilot reported no preaccident 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 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 CEN24LA355.
