Visual meteorological conditions prevailed at the time and no flight plan was filed. The helicopter was substantially damaged and the airline transport- rated pilot and one passenger sustained minor injuries. One passenger sustained serious injuries. The flight originated about 1015 from the Sarasota/Bradenton International Airport, Sarasota, Florida. During an aerial photography flight the helicopter was flown into the water. One of the passengers who was in the right rear seat was wearing a harness which was secured to the seatbelt anchor by a nylon rope. After impact with the water the nylon rope broke and the passenger was ejected from the helicopter. The passenger sustained a fractured and dislocated shoulder.
