PASSENGER CABIN LINING AND INSULATION - DESCRIPTION AND OPERATION
_________________________________________________________________
1. General_______
A. The passenger cabin lining and insulation consists of sidewall lining, ceiling and lowered ceiling lining, and insulation installed outboard or above the linings throughout the passenger cabin.
B. Information on lining and insulation of all doors is included in Chapter 52, Doors.
2. Sidewall Lining (Fig. 1)_______________
A. Sidewall Panels
(1)
Sidewall panels extend from the carpet risers to the overhead stowage bins. The panels are crushed nomex honeycomb between two layers of fiberglass. The exposed surface has a decorative, stain-resistant tedlar covering.
(2)
The inner windowpane mounts near the middle of each panel. Sidewall panels have one or two window cutouts. The inner pane is removable with the panel in place.
(3)
A wash light is near the top of each panel. The ballast may be removed with the panel in place.
(4)
The sidewall panels mount to the airplane structure by support brackets on the vertical edges. A trim strip fits between each panel to cover the fasteners. The upper edge slides into the air outlet extrusion.
B. Carpet Risers and Air Grills
(1)
The carpet riser is a nomex honeycomb-core panel covered. Screws secure the panel to the airplane structure.
(2)
Most carpet risers have air grilles attached by two quick-release fasteners. Depress fasteners to release the air grille and depress fasteners again to attach air grille. Air grilles permit air to circulate into the lower lobe.
3. Ceiling Lining (Fig. 2)______________
A. Sculptured Ceiling Panels
(1)
Sculptured ceiling panels line the ceiling over the passenger compartment aisle. The panels are crushed honeycomb with a tedlar covering on the exposed side.
(2)
Two hinges support the panel on the outboard edge. The inboard edge fits in a groove on the air outlet extrusion. A lanyard on the inboard edge prevents the panel from swinging fully open.
B. Lowered Ceiling Panels
(1)
The ceiling is lowered in entry, galley and lavatory areas to provide space for lights, service units and galley vents. Some panels are hinged for access to these furnishings.
(2)
Curved ceiling panels and transition panels in lowered ceiling areas allow contours to blend with sculptured ceiling panels in the passenger seating area, for a unified appearance.
