757 MAINTENANCE MANUAL
 SIDEWALL LINING AND INSULATION - DESCRIPTION AND OPERATION
__________________________________________________________
 1.  Sidewall Panels (Fig. 1)_______________
 A.  The sidewall panels extend from the carpet risers to the overhead stowage bins. The sidewall panels are crushed nomex honeycomb between two layers of fiberglass. The exposed surface has a decorative, scratch-resistant tedlar covering. The inner window pane 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. A wash light is near the top of each panel. The ballast may be removed with the panel in place. The sidewall panels mount to the airplane structure by support brackets on the vertical edges. A trim strip fits between each sidewall panel to cover the fasteners. Spring clips secure the bottom to the carpet riser. The upper edge slides into the air outlet extrusion.
 2.  Carpet Risers (Fig. 1)_____________
 A.  There are two types of carpet risers that can be used. These types are as follows: The carpet riser is a nomex honeycomb crushed core panel with carpet on the outer side. Two screws attach the panel to the airplane structure. Most carpet risers have air grilles attached by two quick-release fasteners. Push the fasteners to release the air grille and push the fasteners again to attach air grille. Air grilles permit the air to flow into the lower lobe. The carpet riser is a nomex crushed core panel with carpet or tedlar added on the outer side of each panel. The lower edge of the panel is attached to the crease beam angle with clips bonded to the outboard lower edge of the panel. The upper edge of the panel is attached between the lower edge of the sidewall panel and clips added to the outboard lower edge of the sidewall panel. To remove the panel, lift the panel up and inboard to release the panel from the crease beam, then down to release from the lower edge of the sidewall panel. Most panels have air grilles attached to the panels with clips on the outboard side of the air grilles. When the panels are removed, turn the lower clips to remove the air grilles from the opening.
 3.  Sidewall Insulation___________________
 A.  Fiberglass insulation blankets between the sidewall lining and fuselage skin, thermally and acoustically insulate the passenger compartment. The blankets have a water proof covering to prevent condensation from leaking inside the compartment. Snaps, tape, and stitching secure the blankets to the fuselage and attach overlapping blankets.
