Probable cause

Failure of the pilot to adequately perform inflight fuel consumption calculations to ensure the adequacy of the fuel supply for the flight's completion. Contributing to the accident was the failure of the pilot to consider the impact of the stronger than anticipated headwind component to the fuel requirements for the flight.

Analysis

The airport UNICOM operator reported that the he was in radio contact with the pilot. The operator stated that the pilot reported he was out of fuel and executing an emergency landing about 10 miles north of the airport. The pilot said that he departed btf with 38 gallons of usable fuel on board for the 350 NM trip, which he reportedly had made many times before. The pilot said that the typical enroute time for the trip was 3.5 to 4.0 hours with a fuel consumption of 24 to 28 gallons. After takeoff, the pilot changed the fuel selector to the left tank and ran it dry, a procedure he typically used for this trip. The pilot noted that he encountered headwinds enroute and the left tank went dry earlier than normal, however, 'the early switch did not cause any concern.' At the time of the accident, the estimated elapsed time enroute was four hours and forty minutes.
