Before departing Youngstown, OH, the pilot filed two IFR flight plans, one for a flight to Plattsburgh, NY, the other for a return flight from Plattsburgh back to Youngstown. After a 2 hour and 10 minutes flight to Plattsburgh, 70 gallons of fuel was added, but the person who serviced the aircraft indicated the tanks were not full after servicing. The plane then made a 10 minutes flight to Burlington, VT, but no fuel was added at Burlington. The pilot then took off on a return flight to Youngstown. During the descent phase to Youngstown, the pilot requested vectors to the closest airport. He was provide vectors to the Chess Lamberton Airport and advised it was 6 miles away. A short time later, the pilot said the aircraft had lost power. Subsequently, it crashed in rolling, wooded terrain. During an exam, no fuel was found in the aircraft. No other evidence of a malfunction or failure was found. With the passenger and cargo load, a maximum of about 104 gallons of fuel could have been used without exceeding the certificated gross weight of the aircraft. At 45 to 55% power, the aircraft burned 17 to 22 gallons per hour. Wind gusts 30 knots. All six occupants were killed.
