The NTSB's narrative final · quoted from the NTSB record
The flight was conducted to allow the owner to accrue two hours of instruction for insurance purposes. The flight instructor was performing a landing when the accident occurred. According to a statement by the owner, "During landing roll-out aircraft drifted toward right side of runway at which time the instructor exclaimed 'I don't have brakes over here'. Brakes were applied by trainee [owner] causing aircraft to nose over and come to rest on its back." Brakes were installed only in the left seat position. The flight instructor was seated in the right seat position. No pre-existing anomalies were found during a postaccident inspection of the aircraft.

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 CHI00LA216.
