Narrative:
The student pilot, formerly commercial-rated, took off, maintained a level flight attitude for about 5 seconds, then put the airplane into a steep climb. A witness then heard the engine 'cut out' and saw the airplane in a steep left bank, rapidly losing altitude. During the descent, the witness heard several backfires. The airplane leveled its wings, but continued a 25-degree descent as it disappeared below a tree line. It crashed into a shallow river, next to which, was a large field. The empennage stuck out of the water at a 40-degree angle, and was buckled on the right side. There was a strong smell of auto gas, though the airplane had no STC for its use. One propeller blade was embedded in the riverbed, with scratches emanating from the leading edge at varying angles. The other propeller blade exhibited S-bending , severe leading edge pitting, and chordwise and lengthwise scratching. Examination of the engine did not disclose evidence of mechanical malfunction. The student pilot's commercial license was permanently revoked in 1996, after he was observed flying during a suspension. He had about 10 hours of flight time since starting to fly again, about a week earlier.

Probable Cause: The student pilot's failure to maintain control of the airplane, resulting in an inadvertent stall/spin.
