The NTSB's narrative final · quoted from the NTSB record
The pilot reported that he was flying a visual approach for landing when, at 200 ft above ground level (agl), he encountered a “microburst.” The right wing rose about 30° and the airplane turned to the left. He corrected with right aileron and rudder control inputs; however, the airplane continued to the left. When he finally was able to regain control the airplane, he was left of the runway at 50 ft agl. He elected to land in an open field adjacent to the runway. After touchdown, a tailwind increased his ground speed to about 50 kts and the right wing collided with a fence as he attempted to decelerate. The airplane’s right wing was substantially damaged. No evidence of a preexisting mechanical malfunction or failure was found during the postaccident examination of the wreckage, and no mechanical anomalies were reported by the pilot.

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 ERA21LA220.
