The NTSB's narrative final · quoted from the NTSB record
The pilot reported being cleared to land by air traffic control and reported being cautioned of wake turbulence by an airplane that landed ahead in sequence. The pilot aimed to touchdown at a point beyond the presence of the wake turbulence. The airplane encountered light turbulence prior to landing and contacted the runway misaligned with the runway centerline. The pilot applied opposite input correction which produced a roll force resulting in the right wing contacting the ground, substantially damaging the airplane. The pilot reported that there were no preaccident mechanical failures or malfunctions 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 WPR23LA277.
