The pilot of the Cub Crafters CCK was on approach to landing at an airport in Cookson, Okla., when the engine lost power. His attempt to restart the engine were unsuccessful, and he lacked enough altitude to glide to the runway, so he attempted to make a forced landing on a narrow gravel road.
The left wing hit the top of a tree and the airplane spun around and crashed.
The post-accident examination revealed water in the fuel, in the carburetor, and in the storage supply tank. The pilot surmised that the water was likely due to recent heavy rain showers.
He admitted he failed to check the fuel when he preflighted the airplane, and overlooked checking the fuel storage tank’s fuel filter/water separator.
The NTSB determined the probable cause as a total loss of engine power due to water contamination in the fuel. Contributing to the accident was the pilot’s failure to check the fuel during the preflight, and failure to check the fuel storage tank’s fuel filter/water separator.
