The NTSB's narrative final · quoted from the NTSB record
The experimental amateur-built airplane, operated by an unlicensed pilot, sustained substantial damage on impact with terrain following a flat spin encountered on base turn. The pilot, in part, stated, "I lost control, went into a stall-spin, and landed nearly flat in the ditch... . The accident was caused by pilot error. I forgot that the owner's manual said that "Solo flight is restricted to the front seat." ... I forgot that one either has to solo from the front seat or add weight to the front seat to solo from the rear seat. ... As I turned base to the west I was still trying to trim the plane and lost attention to airspeed." The pilot's safety recommendation was, "More training in type would have been useful. A placard could be required to "Solo from front seat only"."

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 CHI06CA050.
