The NTSB's narrative final · quoted from the NTSB record
The pilot reported that the engine surged and sustained a partial loss of engine power during a local night flight. He attempted to restore engine power, but was unsuccessful and made a forced landing to an open field where the airplane impacted a ditch, collapsing the landing gear and bending the firewall during the landing roll. The pilot said that the entire flight was performed with the fuel selector on the “BOTH” position and that when the engine first began to surge, the fuel gauges registered a quarter of capacity in each tank. The fuel system consisted of inner and outer interconnected tanks in each wing, which supplied fuel through a non-return valve to a fuel selector, a filter, and a booster pump grouped together near the front left seat, then through the engine-driven pump to the injector unit. Unusable fuel in each wing is 0.5 gallons. Airplane recovery personnel said that no fuel was found in the left wing tanks and about 8 gallons of fuel were found in the right wing tanks, although the gear collapse may have allowed fuel to migrate from the high wing to the low wing. The airplane was examined and no fuel system discrepancies were found. The engine was test run in the airframe and it started and ran normally.

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 WPR11LA246.
