The helicopter was registered to Coy Leasing, LLC, and operated by Westwind Helicopters, Inc., under the provisions of 14 Code of Federal Regulations Part 135 as an on-demand air taxi. The commercial rated pilot and passenger were fatally injured and the helicopter was destroyed. Visual meteorological conditions prevailed and company flight following was in effect at the time of the accident.

A witness, who was located on the ST 317 oil platform reported that he heard the helicopter approach the platform. The helicopter was on a straight in approach to the platform, when the helicopter started to spin in a clockwise direction. The witness added they he heard a "snap" like something broke, and it looked like the baggage compartment door was open and debris was coming out of the baggage compartment during the spin. The helicopter spun 8-10 times, before the helicopter went silent and dropped to the water. The helicopter sank and was recovered from about a depth of 380 feet of water. The tail boom had separated from the main fuselage and was recovered from the surface of the water. One of the main rotor blades, which had separated about four feet from the mast, was not recovered.
