This February 2008 accident report is provided by the National Transportation Safety Board. Published as an educational tool, it is intended to help pilots learn from the misfortunes of others.
Aircraft: Bellanca Super Viking. Injuries: 1 Serious. Location: Mukilteo, Wash. Aircraft damage: Substantial.
What reportedly happened: The pilot was on short final for a touch-and-go landing when the engine lost all power. Because he was at such a low altitude, he did not have time to go through a complete restart procedure so, after switching fuel tanks, he aligned the plane to land on a paved road that was under his approach path. While attempting to land, the plane clipped a power line and descended into the surface of the road.
An inspection of the engine, fuel system, and air induction system did not reveal any system or component anomaly that would have prevented the engine from producing rated horsepower. Both fuel tanks contained sufficient fuel to maintain operation of the engine. Fuel was also found in the fuel manifold valve. The reason for the loss of power was not determined.
Probable cause: Loss of engine power while on final approach for undetermined reasons.
