honeycomb-filling. This side of the panel completes the lining of the cargo compartment on the inner side.
The border is cut at each corner. The cut starts at the edge of the border and continues diagonally to the corner of the honeycomb-filling. Sealing tape is bonded to the side of the border that touches the inner lining of the cargo compartment. The cuts in the border are sealed with this tape.

Frame
The frame is covered with flame-retardant material, attached with adhesive tape. The frame is installed on the decompression panel, on the side that faces out from the cargo compartment.

Latch Assembly
The latch assembly has a housing, which includes a latch and a spring. The latch has a shaped end and is always in the closed position. To open the latch assembly you push the latch back into its housing, against the spring tension. The latch assemblies are installed on the decompression panel on the side that faces out from the cargo compartment.

(4) Protection Devices
The protection devices are installed with screws to the ceiling-panels around each decompression-panel. The protection devices still permit the full function of (BLOW-IN) or (BLOW-OUT) for the decompression-panels. The protection devices protect the decompression-panels against impact from "X" and "Y" directions of misaligned luggage.

(5) Installation Description and Pressure Values
The rapid-decompression panels are installed in cut-outs in the linings of the cargo compartments. The sealing tape on the border makes a seal between the panel and the lining of the cargo compartment. The flame-retardant material fits tightly in the cut-outs of the linings and helps to seal the cargo compartment.

The rapid-decompression panels are installed from inside of the cargo compartment into the cut-outs as follows:
-Push the panel into the cut-out.
-
The shaped end of the latches adjust the position of the panel automatically to the center of the cut-out.
-
The latches are moved into their housings to the open position.
-
The panel is continually pushed over the full surface until the laminated-skin border is flush with the inner side of the linings.
-
The latches snap back to the closed position and engage with the outer edges of the cut-outs.
The rapid-decompression panels that are installed in the ceiling panels of the cargo compartments are kept free. A maximum height to load bulk cargo, is marked on the wall linings of the cargo compartment 2 in. (50.80 mm) below the ceiling.
The rapid-decompression panels that are installed in the FWD wall lining of the FWD cargo compartment are protected. A protection panel is installed on the inner side of the lining in front of the rapid-decompression panels. The panel is attached with brackets, to make a space between the two panels. When bulk cargo is transported, the protection panel keeps the rapid-decompression panels free.
The pressure difference-values between the cabin and the cargo compartment, necessary to release the decompression-panel from the lining, are:
-30 hPa (0.886 in.Hg) if a rapid decompression (BLOW-IN) in the cargo compartment occurs.
-90 hPa (2.658 in.Hg) if a rapid decompression (BLOW-OUT) in the cabin occurs.
B. Dado Panels (Ref. Fig. 004)
The dado panel has a decorative panel with a cover assembly, and a support assembly. The decorative panel is seen from inboard and finishes the interior lining of the cabin from the upper sidewall-panels to the floor. It attaches the dado panel to the fuselage structure. The cover assembly is installed on the outboard side of the decorative panel.
The support assembly is installed on the outboard side of the decorative panel and attaches the dado panel to the floor. Decompression plates are installed in cut-outs in the back wall of the support assembly. The top edge of the plate is attached with half-hinges to the back wall and can move inboard and outboard. The bottom edge of the plate is held in the cut-out with stop-plates attached on both sides of the back wall.

CES Insulation material is bonded on to the inboard side of the back wall and the inboard side of the decompression plates.
The pressure difference-value between the cabin and the cargo compartment, necessary to release the decompression panel in the support assembly, is 0.05 hPa (0.0014 in.Hg)
C. Air Grills
(Ref. Fig. 005)
The air grills are installed in some closed modules, for example stowages and lavatories. 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320飞机维护手册 AMM EQUIPMENT/FURNISHINGS 设备4(173)
