What happened
While cruising at 8,500 feet, the pilot observed that the left fuel gauge was reading lower than normal. As the pilot began an approach toward the destination, the right fuel gauge dropped suddenly, and the left gauge indicated the tank was almost empty. Following this, the engine quit. While attempting a forced landing, the aircraft collided with utility lines.
The investigation
An examination of the aircraft's fuel system failed to disclose any anomalies. Prior to departure, the pilot visually verified approximately 30 gallons of fuel were onboard, though the pilot did not use a calibrated dipstick to verify the exact quantity in the tanks. Records indicated that the pilot did not typically top off the fuel tanks. Approximately 2 cups of fuel were drained from each tank during the event.
