Narrative:
During cruise flight, the engine experienced a partial loss of power, and although there was some power being produced by the engine, it was not enough to maintain level flight. The pilot therefore turned on the fuel boost pump and switched tanks, but the situation did not change. He therefore attempted to find a suitable landing area, but he came up short of the only acceptable landing area, a golf course, and impacted a pole as he was touching down on a street just outside of the golf course boundaries. A post-accident inspection revealed that there was air leaking into the fuel system through a worn fuel selector valve stem and a hardened and brittle fuel selector valve O-ring.
Probable Cause: The partial loss of engine power during cruise flight as a result of air being sucked into the fuel system due to a worn fuel selector valve stem and a hardened and brittle fuel selector valve O-ring. Factors include no suitable landing area within the aircraft's reduced power gliding distance, and a pole at the location where the pilot found it necessary to make an emergency landing.
