Flight Details
The pilot conducted a visual inspection of the fuel tanks prior to departure. The right tank was observed to be just over half full, and the left tank approximately one-quarter full, leading to an estimated total of 16 gallons of fuel. The pilot noted that although a visual check confirmed the presence of fuel, accurately judging the quantity was difficult.
Based on a fuel consumption rate of 10 gallons per hour, the pilot calculated an endurance of at least 1.5 hours, which was considered sufficient for the planned flight.
Fuel Management
During the flight, the pilot switched fuel tanks periodically. The right tank was used for the first 25 minutes, then the left tank for the next 25 minutes. After switching back to the right tank, the right fuel gauge shortly thereafter indicated empty. The pilot then switched back to the left tank.
Engine Failure and Forced Landing
Approximately 12 miles from the destination, the left tank ran dry. Shortly thereafter, the engine lost power. The pilot executed a forced landing in a field.
Damage
During the landing, the left wing tip struck a berm. The impact sheared off the left wing and breached the left fuel tank. The firewall was buckled, and the engine separated from the firewall.
Pilot Statement
The pilot reported that he "should have had enough fuel for the trip but unfortunately that proved not to be the case."
