The NTSB's narrative final · quoted from the NTSB record
At the conclusion of a Title 14, CFR Part 91 flight, the commercial certificated pilot was landing an experimental/exhibition airplane at a rural airport after performing about 20 minutes of aerobatic flight in a nearby aerobatic practice area. Witnesses reported that the airplane appeared to fly a left (southeast) downwind pattern, paralleling the runway. Near the approach end of the runway, the airplane made a right turn of about 45 degrees, away from the runway, then made a steep left turn, toward the runway. The airplane was then observed to level the wings and descend toward the ground with about a 10 degree nose-down attitude. The airplane collided with the ground in what witnesses described as a flat, level attitude with a high vertical velocity. The airplane bounced and struck the ground a second time, coming to rest within about 50 feet of the initial impact point, and about 15 degrees to the right of the runway heading. The airplane came to rest about 100 feet to the right, and about 850 feet past the approach end of the runway. Inspection of the airplane disclosed no evidence of any preimpact mechanical anomalies.

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 ANC06LA026.
