A pilot experienced a total loss of engine power while approaching an airport after failing to reposition the fuel selector to the main tank. The subsequent forced landing resulted in collision with vegetation and a broken wing.

Event Summary

A pilot reported that before departure, both wing tip tanks were full and the main tank was at least two-thirds full, providing adequate fuel for the flight. After takeoff, the pilot selected the right tip tank as the fuel source. Later, while en route, the pilot switched the fuel selector to the left tip tank.

Approach and Power Loss

As the airplane neared the destination airport, the pilot became distracted while speaking with a passenger. The prelanding checklist was not followed, and the pilot failed to move the fuel selector back to the main tank, which still contained adequate fuel. Approximately 2.5 miles from the airport, all engine power ceased.

Forced Landing

The pilot then repositioned the fuel selector to draw from the main tank, but engine power was not restored as the airplane descended from the traffic pattern. A forced landing was made on the rough terrain below. During the rollout, the airplane collided with vegetation, resulting in a broken wing.

Probable cause

The pilot's failure to reposition the fuel selector to the main tank, which contained adequate fuel, leading to fuel starvation and loss of engine power.
