A helicopter equipped with permanent floats settled into the water after taking off from a fishing vessel with a tailwind, resulting in main rotor and tail rotor contact.
What happened
The pilot initiated takeoff from a fishing vessel while experiencing a tailwind condition. During the initial climb phase, the helicopter descended into a low attitude relative to the water surface. The main rotor blades made contact with the tail boom, and subsequently, the tail rotor struck the water.
Despite the mechanical contact, the aircraft remained in an upright position due to its permanent float equipment. No further details regarding injuries or additional damage are provided in the source record.
The investigation
A post-incident examination of the helicopter's engine was conducted. The inspection revealed no discrepancies or mechanical faults within the powerplant that would have contributed to the incident.
