Read the full NTSB narrative

Both the pilot and the pilot-rated passenger reported that they had planned a flight from Walla Walla to Kelso and return. At Kelso, the airplane was fueled with 16.8 gallons. The pilot and passenger thought that only 10 gallons were used. During the return flight, the engine lost power after 2 hours 45 minutes. The pilot-rated passenger made the forced landing. Night conditions prevailed. During descent, the airplane collided with a powerline and trees. The right wing fuel tank was ruptured and no fuel was present. The left wing contained approximately 1-1/4 gallons of fuel. Computations of fuel flow based on the first leg of the flight were applied to the return leg, and the computed fuel consumed would have been about the amount required to sustain engine power for the duration of the flight.
