The pilot stated that while on approach, within about 300 to 400 yards of the oil platform, as he increased collective input to control the rate of descent, the engine failed to respond normally. As collective input was increased he said the rpms decreased and did not recover, so he stopped applying collective to stop the rotor rpms from decreasing below 90 percent. According to the pilot, no other adverse indications were observed, and the rate of descent increased. He said he applied the remaining collective pitch input to arrest the rate of descent just prior to impacting the water. After impact he said he tried 2 times to inflate the floats, but both attempts were unsuccessful. He and both passengers exited the helicopter, and it sank in about 600 feet of water, and was not recovered.
Probable Cause: A loss of engine power for undetermined reasons while on short final to land on an oil platform in the Gulf of Mexico, which resulted in the pilot ditching the helicopter into the water.
