What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The aircraft departed from westport airport, 4F1, on a flight to pogue Oklahoma, kowp. The nearest weather reporting station, kowp, indicated weather conditions, at the time of the flight, winds from 180 at 5KTS, visibility greater than 10 sm, clear, barometric pressure 30.07. The pilot was on a solo flight with no passengers. The aircraft lost engine power during the cruise segment of flight over lake keystone in Oklahoma, approximately 1800 feet MSL. The pilot stated he initiated emergency procedures and landed in a field south of lake keystone after failure to recover loss of power. The pilot stated he departed westport with the right outboard fuel tank at 4 gal, right inboard fuel tank full at 19 gal, left outboard fuel tank at 12 gal, left inboard fuel tank half full of fuel (left inboard not measured with a fuel stick). The pilot stated he departed westport with the fuel selector on the right inboard tank. The pilot also stated he sumped all 4 fuel tanks prior to departure with no contamination noted and that he measured the 3 of the 4 fuel tanks with a fuel measuring stick. The pilot stated the fuel remaining on the day of the event was from a previous cross country flight on March, 2016. No other flights were made since that date. The pilot had a minor injury (laceration) to the forehead. On FAA arrival to scene, the aircraft was positioned with a landing direction to the southwest, no apparent fire residue noted. Fuel was found in 3 of the 4 fuel tanks. The right outboard tank appeared empty. All other tanks had noticeable fuel, however, none of the fuel tanks could be sumped to determine quantity due to the lower surface of the wing at ground level. Post accident inspection of the aircraft did not reveal any abnormalities within the engine, airframe, propeller, or accessories. An eye witness stated he saw the aircraft flying over the tree line south of the lake, over meadowood road, flying 50-60 feet above the tree line. He stated he heard the engine "sputtering", "like a missing cylinder", "sounded like a motorcycle". He stated the sound was heard from over the lake until impact was heard, described as a "crunch".
