What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Pilot of N9AT, BHT-206-B model aircraft was making his approach to SS-154 platform in the Gulf Of Mexico when he heard a loud noise and a bang. The pilot, at 300 ft AGL initiated auto rotation and inflated his float system and landed the aircraft in the water. No injuries to the pilot, and no passengers onboard. Aircraft did not have any substantial damage. The tail rotor made contact with the water, and the sudden stoppage resulted in the number one drive shaft to shear.
