The airplane experienced a total loss of engine power during a skydiving flight. After the pilot switched
the fuel tank selector from the left fuel tank to the right fuel tank position, the engine restarted. The pilot
continued the flight. While returning to the departure airport and preparing for landing, the pilot
switched the fuel tank selector back to the left fuel tank position because the fuel gauge indicated a
greater fuel quantity. About 1 minute later, the engine quit. The pilot landed the airplane left of the
intended runway, about 200 feet from its end, and the airplane flipped over and pivoted on its nose.
Examination of the airplane revealed that the left fuel tank vent system was obstructed with an unknown
substance. It is likely that the obstruction prevented fuel flow to the engine and resulted in a total loss of
engine power.
