Analysis
When on short final the pilot attempted to add power for glide path correction but received no engine response. He switched tanks and opened the strainer drain valve because of previous water contamination problems. He made a left turn to make an emergency landing on a river bank, and about five seconds before touch down, switched on the fuel boost pump. Still no response from the engine occurred. The aircraft landed on the river bank, collapsing the nose gear and receiving other airframe damage. Subsequent investigation revealed the presence of water in the fuel sump. The pilot stated that he had been experiencing fuel contamination from a variety of sources.
