BEFORE DEPARTING SMITH POND, MAINE, THE PILOT CHECKED THE FUEL AND ESTIMATED HE HAD BETWEEN 30 AND 40 GALLONS ON BOARD. HE FLEW TO WATERVILLE, THEN TO KATACHDINE LAKE, AND WAS ON THE NEXT LEG OF THE FLIGHT WHEN THE ENGINE LOST POWER. HE SWITCHED TANKS AND THE ENGINE STARTED FOR A FEW SECONDS, THEN LOST POWER AGAIN.
