6. STAIR
The aircraft is equipped with a built − in folding stair
at the main door. When not in use, the stair is
folded and slid along a rail to its stowed position
forward of the main door.
After the main door is opened, the stair is unlocked
from its stowed position and slid to the door open-
ing where it locks into position. It is then extended
and lowered onto the ground by hand.
The stair itself is not to be considered as emergen-
cy equipment. However, its function has bearing on
the use of the Main door as an emergency exit.
NOTE
Evacuation procedures should not include the
stair to be used in an emergency evacuation.
The reason for this is the possibility of a bent
slide hand rail which could render the stair un-
movable or stuck in a middle position thereby
blocking the exit.
