EMERGENCY EXIT HATCH WINDOW - DESCRIPTION AND OPERATION
_______________________________________________________
1. General_______
A. The emergency exit hatch window, installed in each emergency exit hatch in the passenger cabin, is located in the upper portion of the hatch and is similar in external appearance to the passenger windows (Fig. 1). The window consists of outer and inner panes and an inner-most plastic pane. The inner-most pane is nonstructural and is mounted in the emergency exit hatch trim panel (AMM 52-21-12/401, Emergency Exit Hatch Lining). The outer and inner panes are each capable of taking the cabin full pressurization load. All three panes are acrylic, the structural panes being formed to improve resistance to crazing.
B. Each emergency exit hatch window is designed as a plug type window subject only to the pressure acting on it. The outer window pane of stretched acrylic plastic is rectangular in shape with rounded corners and a routed outer edge to fit the window outboard frame. The pane is curved to fair with the fuselage contour. The inner window pane is made of modified acrylic sheet. It is shaped similarly to the outer pane, but with an unbeveled edge which is seated on the window inboard frame.
C. The outer pane has a peripheral seal of molded synthetic silicone rubber. An outer pane spring assembly and ten outer pane spring retainers secure the outer pane in position on the window outboard frame. The inner pane is pressure sealed to the window inboard frame and outer reveal and is secured by screws which are spaced around the periphery of the window retainer.
D. The emergency exit hatch window is designed to preclude fogging and frosting by means of multiple pane construction with intervening cavities essentially isolated from cabin interior air conditions.
