What happened
At the time of departure, the right fuel tank was empty while the left fuel tank contained 17 gallons. The fuel selector was set to the 'BOTH' position for takeoff. Following the takeoff, the pilot switched the selection to the left fuel tank.
Within two to three minutes of the climb, the engine began to sputter and run roughly. The pilot attempted emergency checklist procedures, but these actions failed to restore power to the engine. As the pilot prepared for a forced landing, the approach path for the selected runway was obstructed by power lines. After clearing the power lines, the aircraft's airspeed decreased, resulting in a hard landing on the runway. No injuries were reported.
The investigation
Investigators examined the flight controls and confirmed continuity throughout the system. An inspection of the fuel system showed continuous fuel flow and no evidence of any leaks. The engine was also inspected, and investigators found no discrepancies that would have prevented normal operation. Additionally, the carburetor was disassembled and subjected to a flow test; no variations or mechanical discrepancies were identified during this process that would have hindered the operation of the carburetor.
