AIKENS, SC, USA
N7312V
Bellanca 17-30
The pilot experienced a loss of engine power en route to his destination. He initiated an emergency descent for a forced landing. The airplane collided with two trees in the intended landing area. According to the pilot, the airplane had a fuel endurance of 4.8 hours, and he had flown about 3.0 hours since the last refueling. Examination of the engine assembly disclosed that there was a fuel leak around the shaft in the metering unit. The nature of the leak was a steady stream, such that, it was not possible to flow test the unit. Smaller leaks were also found in the fuel pump from the shaft seal and the adjustable orifice o-ring. The control linkage on the fuel metering unit and the throttle body were excessively worn. No fuel was recovered from the fuel system during on-site examination.

As he maneuvered for a landing in a nearby field, the airplane collided with two trees in the intended landing area. According to the pilot, the airplane has a fuel endurance of 4.8 hours and he had flown about 3.0 hours since the last refueling. The examination of the engine assembly disclosed that there was a fuel leak around the shaft in the metering unit. The nature of the leak was a steady stream, such that, it was not possible to flow test the unit. Smaller leaks were also found in the fuel pump from the shaft seal and the adjustable orifice o-ring (see attached report of the engine examination).The control linkage on the fuel metering unit and the throttle body was excessively worn. No fuel was recovered from the fuel system during the on site examination.
excessive wear of the fuel metering unit/shaft, which resulted in a fuel leak and premature exhaustion of the fuel supply.
