Doors
The airplane has ten main deck passenger entry doors, one flight deck door (the
flight deck/passenger cabin entry), two upper deck emergency doors, and three
cargo doors. It also has two electrical and electronic (E/E) equipment access
doors.
Door Locations
Flight Deck Door
The flight deck door opens into the flight deck.When the door is closed, a viewing
lens in the door allows observation of the passenger cabin.
An electric lock latch mechanism, controlled by the flight deck door switch,
allows the flight deck door to be locked. The door can be opened any time from
the flight deck side. When the door is locked, a key is required to open the door
from the passenger cabin side. The door unlocks with the loss of electric power.
A break–away panel in the base of the door allows the door to open if the bottom
of the door is jammed. A door latch mechanism allows the locked door to be
forced open without permanent damage to the lock. Application of sufficient force
opens the locked door in either direction. An angled door jam forces the door open
into the flight deck in case of surrounding bulkhead deformation.
CAUTION: Forcing the door open into the passenger cabin causes
permanent damage.

Systems Description
Passenger Entry Doors
The main deck passenger entry doors are used to enter and exit the airplane, and
serve as emergency exits. The ten passenger entry doors are paired along the
airplane fuselage. The doors are identified 1 through 5 left, and 1 through 5 right.
The passenger entry doors can be opened or closed manually from inside or
outside of the airplane.
The entry doors are translating, plug–type doors. During opening, the door first
moves inward and upward, then translates outward and forward. Each door is held
in the open position by a gust lock. The gust lock drops into a latch as the door
nears its forward limit of travel. A window in each door allows observation outside
the airplane.

Passenger Entry Door 1, 2, 4, and 5 Slide/Raft Operation
When the door mode select lever is in AUTOMATIC position and the door
operating handle is rotated 180 degrees, the door begins to open and the power
assist opening system activates.
The flight attendant must release the door operating handle and continue to assist
the door opening motion by using the assist handles on the door and on the door
surround panel until the door is in the full open and latched position. The
door-mounted escape slide/raft deploys and inflates. If the slide/raft does not
inflate automatically, pulling the manual inflation handle inflates the slide/raft.
When the door is to be opened from the interior and slide deployment is not
desired, the door mode select lever must be in MANUAL position.
When the door mode select lever is in AUTOMATIC position and the door is
opened using the exterior door handle, the door mode select lever handle
mechanically positions to MANUAL and the door may be opened without slide
deployment.
When the door is closed using either the exterior or interior door handles, the door
mode select lever remains in MANUAL and must be positioned to AUTOMATIC
to provide automatic slide deployment.
The door mode select lever should not be moved from MANUAL to
AUTOMATIC or AUTOMATIC to MANUAL unless the door is fully closed.
Note: If both body gear are not extended, the airplane may tip tail down on the
ground. Door 1 escape slides are then unusable.
