Analysis

The plt stated that while preparating for flt, he was starting the eng by hand propping. The eng flooded, so he opened the throttle, turned the fuel valves & magnetos 'off' & propped the eng 10 times to pump fuel from the cylinders. He then returned to the cockpit, turned on the magnetos & verified the fuel valves were off, but forgot to close the throttle before resuming the procedure. Also, he did not tie-down the acft or chock its wheels. When he commenced hand propping, the eng started & went to a high power setting. Subsequently, the acft hit svrl objects (including a utility pole) & went into about 3 ft of water in a lake, before the eng stopped.
