Accident Sequence
While climbing after takeoff, the dual student who was flying the airplane switched fuel tanks. Shortly after, the engine quit. The pilot observed no fuel pressure or fuel flow on the gauges. Attempts to restart the engine were unsuccessful. The pilot selected a field for a forced landing, but could not reach it. The airplane subsequently crashed into trees.
Postcrash Findings
An FAA inspector conducted a postcrash examination of the aircraft. The inspection revealed that the engine fuel system contained no fuel. Additionally, the electric fuel boost pump switch had a loose wire, which prevented the pump from operating when in the on position. It was also noted that a fuel tank had been run dry on the previous flight.
Flight Manual Guidance
The flight manual states that if a fuel tank has been run dry and is refueled with the fuel selector in the off position or on another tank position, air may become trapped in the fuel lines. The manual recommends eliminating this air by running the engine on the refueled tank before takeoff.
