DOORS AND WINDOWS
DESCRIPTION AND OPERATION
1. Doors and Windows − General
One crew door and window assembly is
mounted in a door frame structure or ”door
pillar assembly” on each side of the aircraft.
One cabin door and window assembly is
mounted on a sliding track mechanism on each
side of the aircraft. One baggage door assem
bly is mounted in the rear door frame struc
ture. These attachment substructures are part
of the fuselage structure.
2. Crew/Cockpit Door Assemblies
(Ref. Figure 1 and Figure 2)
The crew or cockpit door assemblies consist of
a graphite/epoxy inner and outer skin adhe
sively bonded together to form a box section
assembly. The cockpit doors operate on a
pivoting hinge mechanism. Each door has one
window transparency mounted to the door
structure by means of a ”Z” shaped window
seal that mounts to the periphery of the
window and the mating flange of the door
frame. The door assemblies are secured with a
locking latching door mechanism that can be
opened from the inside or outside. A quick
release mechanism is also standard on each
door assembly. Currently, there is an optional
door with quick release pins on the outside.
This option door does not come with gas struts
(Ref. CSP-900RMM-2, Section 01-00-00,
Optional Equipment List).
3. Cabin/Passenger Door Assemblies
(Ref. Figure 3 and Figure 4)
The cabin doors consist of a graphite/epoxy
inner and outer skin adhesively bonded
together to form a box section assembly. The
cabin doors operate on rollers and an upper
and lower door track mechanism which allows
the doors to be slid aft for access to the cabin
area. Each door has one window transparency
mounted to the door structure by means of a
”Z” shaped window seal that mounts to the
periphery of the window and the mating flange
of the door frame. An emergency pull strap is
incorporated in the window mounting which
allows the window to be pulled in for emergen
cy egress. The cabin doors have a locking
latching door mechanism that can be opened
from the inside or outside.
4. Baggage/Cargo Door Assembly
(Ref. Figure 5)
The baggage/cargo door is a graphite/epoxy
faced Nomex honeycomb cored structure.
Facings are typically two outer plies and one
inner ply with doubler plies adjacent to hinge
points. The baggage door operates on a
pivoting hinge mechanism opened from the
outside for access to the rear baggage/cargo
area. The baggage/cargo door has a locking
latching mechanism.
