What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Pilot was maneuvering when he felt a shudder and the helicopter yawed rapidly to the right. Pilot applied left peddle but was not able to immediately stop the yaw. He is uncertain of the number of revolutions. He briefly regained some control of the aircraft but had such a descent rate at this point that water impact was imminent. At the last second he banked to the right so the main rotors would impact the water. At the time of loss of control the apparent wind was from 45-60 degrees left of the nose of the helicopter.
