Accident Details
The pilot reported that after takeoff and initial climb, the engine 'began to spit and sputter', lost rpm, and would only produce partial power. The pilot performed a forced landing, during which the airplane collided with a pole, a guardrail, and a roadway.
Investigation Findings
Examination of the engine and its accessories revealed no anomalies. However, examination of the auxiliary fuel pump revealed ice in the filter area. After the pump was thawed to room temperature, approximately 1 ounce of water was drained. Additionally, removal of the engine-driven fuel pump revealed water in its inlet and outlet sections, and disassembly of the pump showed water in the pump diaphragm area.
Preflight and Refueling
Records indicate that the airplane was refueled the night before the accident flight. Both the pilot and the passenger reported that the preflight inspection was completed in approximately 5 minutes prior to takeoff.
