Incident Overview
A pilot conducted a flight after topping off the fuel tanks the previous day. Approximately one hour into the flight, the engine began running rough, and the fuel flow indicator dropped to 4 gallons per hour. The pilot attempted to restore engine operation by switching fuel tanks, enriching the mixture, and activating the boost pump. These actions resulted in a momentary increase in fuel pressure before it dropped again.
Forced Landing
Unable to maintain engine power, the pilot executed a forced landing in a field described as uphill. During the landing, the nose gear separated from the airplane.
Post-Accident Inspection
An examination of the aircraft revealed that the left fuel tank was empty, while the right fuel tank was between one-half and three-quarters full. The fuel selector was positioned on the left tank. No mechanical discrepancies were identified in the engine or fuel system that could have caused the loss of power.
