Abstract
A passenger door rapid emergency egress (PDREE) system that can be used on airplanes, such as the Cessna 206, allows the forward cargo door to be safely jettisoned allowing unrestricted egress for occupants in the rear of the aircraft. Unlike the manufacturer's design, the (PDREE) system is designed to work when the landing flaps are down. Extended flaps interfere with the exit door. Mechanical levers in the PDREE system are designed to function even if used improperly. The PDREE system opens and allows the passenger door to be jettisoned when the door is closed, or closed and locked, and binding loads are placed on the hinges. This is accomplished through the use of robust, non-corrosive, stainless steel mechanical levers and pins. A separate, red emergency handle safely stowed to prevent accidental activation, is easily accessible in the back of the aircraft.
