3. Description and Operation
_________________________
A. Sidewall Linings and Ceiling Panels
The sidewall linings and ceiling panels in the AFT cargo hold prevent damage to the aircraft structure. They are made of flame-resistant synthetic material and permit fast decompression. The sidewall linings and ceiling panels are attached with quick-release fasteners to:
-
the support struts
-
the cross beams
-
the cargo compartment brackets.
The sidewall linings and ceiling panels are a sandwich construction. They are made of honeycomb core, which is bonded between prepreg layers.
B. Deflector Strips
Deflector strips are installed at the center of the ceiling panels in the AFT and the BULK cargo compartment. The deflector strips keep a clearance between the top of the cargo and the ceiling panels. The deflector strips also make sure that the decompression panels for a fast decompression can open.
C. Smoke Detector Panels
The AFT and the BULK cargo compartments are completed with the smoke detection system. The ceiling panels have therefore cutouts for the smoke detector panels. They are installed at the center of the ceiling panels between FR48 and FR49, FR52 and FR53, FR56 and FR57 and between FR62 and FR63.
D. Air Conditioning Inlets and Outlet
The left and right sidewall linings have cutouts (inlets and outlet) for the air conditioning of the AFT cargo compartment. The air conditioning system moves air into the AFT cargo compartment and keeps it at specified temperatures. The access panel between FR47/51 and FR52 give access to the extraction components of the air conditioning system.
E. Rapid Decompression Panels
Rapid decompression panels (blow-in and blow-out ) are part of the cargo compartment linings. They are installed in the cutouts of the ceiling panels and lateral right sidewall lining at FR52A and FR56. Catch assemblies hold them in the cutouts. The rapid decompression panels are sealed to the ceiling panels and to the sidewall lining with adhesive tape.
F. Divider Net and Door Net
There are two types of nets installed in the AFT cargo hold. The divider net at FR59 divides the cargo hold into the AFT and the BULK cargo compartment. The divider nets at FR47.5 and FR53 divides the AFT cargo compartment in three sections. The door net prevents damage to the cargo compartment door. The door net and the divider net are attached to the tie-down and net attachment points.
G. Tie-Down and Net Attachment Points
Screws attach the tie-down and net attachment points to the fuselage structure. These attachment points are used for:
-
the attachment of the door and divider nets
-
the attachment of the straps which hold large or small items of bulk cargo.
H. Loading Area Light
The loading area light is a spotlight and is installed in the ceiling panel at the AFT cargo compartment door. The intensity of the loading area light permit persons to read labels on equipment near the cargo compartment door.
J. Cargo Compartment Lighting
The AFT cargo hold has a lighting system with neon tubes and is installed in the center of the ceiling panels. Toggle switches installed at the AFT and the BULK cargo compartment door control the lighting system.
