On October 2, 2007, about 1000 mountain daylight time, a Robinson R44 II N644BS, rolled over at a watercraft landing zone in Lake Powell, Utah. The pilot was operating the helicopter under the provisions of 14 CFR Part 91. The private pilot and one passenger sustained minor injuries; the helicopter sustained substantial damage.

The helicopter sustained substantial damage to the main rotors, tail boom, and cabin.
