Incident Overview
A single-pilot cargo aircraft experienced an engine malfunction shortly after takeoff on the final leg of its flight. The pilot reported that the engine began to sputter. In response, the pilot moved the fuel selector from the left tank to another position and activated the boost pump. Shortly thereafter, the engine ceased operation. The pilot then chose to land the aircraft in a public park.
Sequence of Events
During the emergency landing, the left wing separated from the aircraft. The pilot, who was the only person on board, received minor injuries. Subsequent investigation revealed that the fuel selector had been turned to the 'off' position. A check of fuel quantities showed less than five gallons in the left tank and approximately twelve gallons in the right tank.
Investigation Findings
The investigation identified several factors leading to the engine failure and subsequent forced landing:
- Loss of engine power due to fuel starvation (non-mechanical).
- Inadequate preflight planning and preparation by the pilot.
- Improper positioning of the fuel tank selector by the pilot.
- Inadequate in-flight planning and decision-making.
- Misjudgment of procedures and directives.
- Diverted attention.
- During the forced landing, the aircraft collided with trees, and the wing separated.
Probable Cause
The official probable cause was determined to be loss of engine power due to fuel starvation, resulting from the pilot turning the fuel selector to the 'off' position. Contributing factors included inadequate preflight planning, improper fuel selector positioning, and inadequate in-flight planning and decision-making by the pilot in command.
