Incident Overview
According to the official investigation report, as the airplane neared its destination, the pilot switched from the right to the left fuel tank. Approximately five minutes after this action, the engine experienced a total loss of power. During the subsequent forced landing approach, the airplane struck electric powerlines and then collided with the ground.
On-Scene Examination
Upon examination of the airplane, investigators found no fuel in any of its fuel tanks. A small amount of fuel, about half an ounce, was present in the fuel sump, and the carburetor contained no fuel. Inspection of the main fuel tank bladders revealed that the outboard, top section of the left bladder was folded over and collapsed.
Fuel System Findings
The pilot reported that the fuel gauges did not work. The fuel gauge sending units, located next to the wing root, were examined. Research indicated that the fuel sending units would read the left fuel tank volume level based on fuel level rather than actual quantity.
Summary
No further details regarding the aircraft type, registration, date, operator, location, occupants, injuries, or damage were provided in the source. The investigation did not state a probable cause for the incident.
