Analysis

The acft descended into the Gulf Of Mexico from a 100 ft AGL hover after the plt lost yaw control downwind of an offshore oil platform in 35 kt winds. As the acft came to a hover it began a turn to the right even though it was headed into the wind. Full left pedal did not stop the spin according to the pilot who tried to fly away rather than autorotate into 10 ft seas. The acft continued to spin and then lost alt to water contact where it rolled and started to sink. The pilot escaped through the broken windshield.
