A pilot entered the traffic pattern for landing and experienced an engine power loss during a right turn. The pilot overshot the landing point, attempted a 180-degree turn, stalled the airplane, and collided with terrain short of the runway.

Accident Overview

The pilot of an airplane was conducting a landing approach when the engine lost power during a right turn in the traffic pattern. The pilot later reported that before departure, the left fuel tank was empty and the right tank was only one-quarter full.

Sequence of Events

After entering the traffic pattern, the pilot made a right turn, at which point the engine ceased producing power. In the ensuing emergency, the pilot overshot the intended landing point. To compensate, the pilot executed a right 180-degree turn back toward the field. During this maneuver, the airplane stalled and subsequently collided with terrain short of the intended runway.

Fuel State

The pilot stated that upon departure, the left fuel tank contained no fuel, while the right tank held approximately one-quarter of its capacity. No further details about fuel management or distribution are available from the source.

Conclusion

The accident involved an engine power loss, an overshoot of the landing point, and a stall during an emergency turn. The airplane impacted the ground before reaching the runway.
