Incident Overview
A helicopter engaged in a fish spotting mission, with the master of the MV Ocean Kim aboard, experienced a sudden loss of yaw control during cruise. The pilot reported hearing a loud bang and feeling vibration in the rudder pedals, after which all directional control was lost. The pilot suspected that the tail rotor had struck a large sea bird, as many birds were present in the area.
Emergency Maneuvers
Despite the loss of yaw control, the pilot was able to maintain directional control by using throttle and collective inputs while flying at 60 knots. The pilot discussed the situation with the captain, briefly considering the possibility of the captain jumping from the helicopter if it could be slowed sufficiently at a low altitude, but only if approved by the pilot.
Ship Support and Evacuation
Meanwhile, the ship lowered small boats and maneuvered to create a smooth water surface. The pilot orbited the area, gradually reducing speed to determine the minimum speed at which directional control could be maintained. At an estimated altitude of 75 feet above sea level and a speed of 45 knots, the captain dove out of the helicopter headfirst. The pilot then executed a running landing on the water and was subsequently hoisted onto the ship's deck.
Injuries and Damage
The captain sustained fatal injuries as a result of the jump. Examination of the helicopter revealed that the tail rotor blades exhibited impact damage.
