Quad City Ultralight Aircraft Challenger I
The non-certificated pilot was flying an unregistered amateur built Quad City Challenger I in cruise flight when the engine "stopped cold." During the forced landing, the airplane struck a power line, and sustained substantial damage to the left wing and fuselage. The airplane was equipped with a non-certificated Rotax 503 engine. The pilot inspected the contents of the fuel tank, and found no contamination. He removed the fuel bowls from the engine's dual carburetors and found them to be full of fuel. He was able to rotate the engine by hand and believed the engine stoppage was caused by an ignition failure.
