The NTSB's narrative final · quoted from the NTSB record
The pilot reported that after a normal landing onto a dirt road, which was covered with loose dirt and gravel, the airplane's right wing collided with a tree. The airplane rotated to the right approximately 20 degrees and began skidding sideways. He attempted to correct with rudder and brakes but the airplane exited the road and subsequently nosed over. According to the pilot, clear skies and a light breeze prevailed at the time of the accident. The pilot reported that there were no preimpact mechanical malfunctions or failures of the airframe or engine that would have precluded normal flight.

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 WPR11CA224.
