The NTSB's narrative final · quoted from the NTSB record
The pilot reported that he was flying the airplane to the annual Experimental Aircraft Association Airventure fly-in at the Wittman Regional Airport (OSH), Oshkosh, Wisconsin, and was proceeding as prescribed in the Notices to Air Missions (NOTAM) pertaining to arrivals to the airport. He stated that the airplane’s engine lost power and he activated the auxiliary fuel pump, which restored engine power briefly. The engine again lost power and the pilot executed a forced landing to a corn field. The airplane nosed over during the landing and incurred substantial damage to the fuselage and vertical tail. Postaccident examination revealed no smell of fuel at the accident site and no evidence of a fuel spill. No usable quantity of fuel was found within the fuel tanks and the tanks were not breached. Examination of the airplane did not reveal any mechanical anomalies that would have precluded normal operation. Automatic dependent surveillance - broadcast (ADS-B) data revealed that the flight lasted about 3.6 hours. According to the airplane operations manual, the maximum flight duration at normal cruise was about 3.9 hours without reserve, but was predicated on using a lean mixture setting. Based on the available information, it is likely that the loss of engine power was due to fuel exhaustion.

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 CEN23LA329.
