The NTSB's narrative final · quoted from the NTSB record
The pilot reported that while conducting a slow flight maneuver for flight testing purposes in an unregistered airplane, he felt a “heavy push up” on the airplane to about 75 ft above ground level. The right wing then lifted and the pilot lost control of the airplane which entered a left descending spiral. The airplane subsequently impacted terrain and came to rest inverted. A witness reported that he observed dust devil weather activity where the airplane was flying at the time of the accident. The airplane sustained substantial damage to the fuselage, both wings, and the empennage. The pilot reported there were no preimpact 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 CEN25LA155.
