Swiss Rotor Solutions has developed a retrofit “bubble” window set for Airbus H125/AS350 helicopters, and recently announced it has achieved EASA certification. FAA certification is in the works and is expected soon, the company said. The kit consists of a new door with the bubble window, a new bow-shaped floor structure that the door conforms to and a floor viewing aperture outboard of the right-hand pilot’s seat.
