The Door Steward™ for the Cessna Cardinal models 177 is a product improvement installation that greatly improves the operation of the aircraft doors. The installation consists of a gas spring attached to brackets mounted on the door behind the arm rest and the airframe . When the door is unlatched the gas spring gently but firmly opens the door to the full open position. The gas spring while in the open position protects the aircraft and occupants from unexpected openings and closings by providing resistance to considerably higher wind gusts and prop wash than the original stops. In addition, the gas spring is extremely simple and reliable. The weight of each door installation is one pound. The original door stops are recommended to remain instaled if still functioning and not interfering with the Door Steward™. Closing the door compresses the gas spring. The gas spring can easily be removed from its brackets to facilitate removal of the aircraft door, replacement of a defective gas spring or to conduct other maintenance.
