Flight Sequence
While en route, the pilot selected both inboard fuel tanks. Shortly after, the right engine began to cough and surge. The pilot attempted to move the selector valve to the outboard tanks, but the engine continued to surge. The pilot did not secure the right engine or feather its propeller. The flight was diverted to an alternate airport.
The pilot's approach planning was inadequate. The airplane's airspeed was excessive and altitude too high to successfully land on the runway. A go-around was initiated with full power on both engines. However, the right engine began to lose power, preventing the airplane from gaining enough altitude to return to the airport.
Landing and Damage
The pilot chose to land on a dirt road. During the landing rollout, the right wing collided with a tree.
Fuel System Examination
Inspection of the fuel system revealed that the right fuel selector valve linkage was bent, and the valve was not fully in the off position, being slightly offset.
