Probable cause
The loss of oil pressure due to metal pieces from the number 5 piston skirt in the oil system, which prevented the oil valve top ball valve from seating. The muddy terrain was a factor.

Read the full NTSB narrative
The pilot shut down the engine and force-landed the airplane in a field following a loss of oil pressure while performing an aerobatic maneuver. During the landing roll, the airplane nosed-over in muddy terrain. Post accident examination showed that a portion of the number 5 cylinder piston skirt had fractured and was located within the oil valve. The oil valve works through the means of gravity operated ball valves which includes two balls and a spring. During normal flight, the top ball valve is closed and the bottom ball valve is open. During inverted flight, the opposite is true. In this location, the fractured piece could prevent the ball assembly of the oil valve from seating.
