NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot reported that he was water-taxiing a fixed-float equipped helicopter in a right sideways direction when the helicopter rolled to the right, impacted the water, rolled inverted, and sank. The pilot, who was the sole occupant, was able to exit the inverted cockpit, inflate his life vest and swim to shore. The helicopter sustained substantial damage to the main rotor system, tail rotor, and fuselage. The pilot reported no preimpact mechanical anomalies with the helicopter. The characteristics displayed by the helicopter were indicative of it encountering a dynamic rollover.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's improper use of the collective and cyclic control during taxi operations, which induced a dynamic rollover.
