Probable cause

A total loss of engine power during initial climb for undetermined reasons.

NTSB analysis

The commercial-rated pilot receiving instruction and the certificated flight instructor (CFI) flew a 50-nautical mile flight to an outlying airport, then boarded the airplane for the return flight. The pilot observed normal indications on the engine instruments throughout the taxi and engine run-up. Shortly after takeoff, the airplane seemed "sluggish," the airspeed began to drop, and the airplane experienced a partial, then total, loss of engine power. During the subsequent forced landing, the airplane clipped a telephone pole prior to impacting a clearing. The CFI stated that he observed no abnormal indications at any time prior to the initial loss of engine power during takeoff. During an engine test run subsequent to the accident, while operating at moderate power, the fuel flow gauge began fluctuating before the engine suddenly lost power. The engine was re-started and again lost power after about 2 minutes. The engine-driven fuel pump was removed and disassembled with no anomalies noted. The fuel line connecting the fuel pump to the fuel servo was removed and examined, and no evidence of blockage or degradation was observed. A visual inspection, flow test, and teardown inspection of the fuel servo and flow divider at the manufacturer's facility revealed no anomalies.
