Introduction
An accident occurred when a single-engine floatplane experienced a complete loss of engine power while on approach to Ely Lake, Minnesota. The pilot had earlier refueled with only 10 gallons of fuel added to the right tank.
Accident Sequence
The pilot had returned from a fishing trip in Ontario, Canada, and landed at Crane Lake, Minnesota, to clear customs. There, 10 gallons of fuel were added to the right fuel tank. The pilot then flew to Eveleth, Minnesota, approximately 90 miles away. From Eveleth, the pilot continued toward Ely Lake.
About three miles from Ely Lake, as the pilot began a descent, the engine lost power. The pilot switched fuel tanks and attempted to restart the engine but was unsuccessful. The left fuel gauge reportedly indicated the tank was still three-quarters full when the power loss occurred.
During the approach to land in a water-filled pit mine, the pilot slowed the aircraft to near stall speed while flying over power lines. The pilot then dove the plane toward the water and flared, but the aircraft stalled when it was approximately five feet above the water.
Damage and Investigation
Upon touchdown, the right float collapsed, and the spreader bar, right wing tip, and propeller were damaged. An investigation revealed that the engine lost power due to a lack of fuel.
