    Description of modification

    This simple and reliable vertical reference door provides a large protruding window to improve the downward vision of the pilot. The door consists of a steel peripheral frame which supports an acrylic “bubble” window. A horizontal member is attached to the lower part of the door to support an arm rest. Conveniently, the door is attached to the airframe with virtually the same hardware as the original crew door. The door does not affect the performance of the rotorcraft significantly. With a cruise pitch setting of 15.5 degrees, the range will decrease only by 6% with one bubble door and 10% with two bubble doors. This installation is available for either or both the left and the right hand side.
