Robinson Helicopter received FAA STC approval for a float option for its five-seat R66 light turbine. The $875,000 float option adds 65 pounds to the helicopter’s empty weight. When not in use, the float tubes stow in low-profile protective covers along the landing gear skids to minimize drag. Primarily for use in emergencies, the floats activate by a lever on the pilot’s collective and inflate within three seconds, allowing the pilot to make an immediate water landing if necessary.
