What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot stated that after the aircraft touched down, he lowered the collective and, while rolling off the power, the aircraft suddenly rolled to the right. This caused the main rotor to contact the ground, separating it from the main shaft and causing substantial damage to the helicopter. The helicopter came to rest on its right side.
