Incident Overview
A pilot en route to Sonoma County Airport in Santa Rosa, California, became concerned about the aircraft's fuel state and decided to divert to Ukiah Airport in Ukiah, California. While proceeding to Ukiah, the aircraft experienced a total loss of engine power due to fuel starvation.
Forced Landing and Collision
During the subsequent forced landing, the aircraft landed long on the runway, overran the departure end, and collided with a localizer antenna. The pilot reported that he had failed to switch to the auxiliary fuel tanks, which still contained fuel at the time of the incident.
Pilot Actions
The pilot's decision to divert was prompted by his concern over the fuel remaining. However, the power loss occurred because the main fuel supply was exhausted while the auxiliary tanks were not selected.
