9. Entrance Stairs
A. Forward Airstair
(1)
The forward airstair (figure 1) is located at the forward passenger/crew entry door and can be operated from inside or outside the airplane. When extended the airstair forms a stairway for passengers and crew to enter or leave the airplane. The forward entry door can be opened and closed without extending or retracting the forward airstair. The airstair can be extended by normal or standby power.

When the airstair is retracted it folds, and telescopes, and is stowed in a compartment immediately below the forward entry door. The compartment is closed by the airstair door which fairs with the fuselage contour. The airstair door is included in the door warning system. For additional information on the forward airstair refer to, Forward Airstair and Door - Description and Operation, Section 52-61-0.
