What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot experienced an undetermined loss of power shortly after takeoff. The pilot executed an emergency landing in an adjacent field. During the latter part of the landing roll, the left main landing gear buckled and the aircraft nosed over due to the extremely muddy conditions of the landing field. Fuel starvation was suspected however, the pilot insisted that sufficient fuel was on board. Investigators could not determine the fuel state with any certainty since the time elapsed to arrive on scene may have allowed for any fuel to drain from the inverted fuel tank.
