C. The aft cargo compartment forward bulkhead is lined with fiberglass panels and formed fiberglass shrouds. Cap strips hold the edges of the panels and shrouds in place. The cap strips are fastened to the structure by screws. The central areas of the panels are fastened to the structure by screws.
D. The aft bulkhead of the aft compartment is lined with aluminum alloy sheet panels, which are held to the structure by quick-release fasteners or screws. The panels that line the forward compartment aft bulkhead are made of fiberglass skins and foamed plastic cores. A plastic backed sheet metal grille covers the blowout panel opening in the forward compartment bulkhead.
3. Insulation__________
A. Insulation blankets are outboard of the sidewall lining and below the compartment deck. Most blankets are fastened to structural members by plastic studs and clips. Larger sidewall blankets are further held in place by nylon lacing, which runs across the inboard surfaces of the blankets and between adjacent body frames. Some parts of certain blankets are also fastened by velcro tape. The blankets above the cargo compartment doorways, and a few of the smallest blankets, are fastened only by velcro tape.
B. A typical blanket has a layer of fiberglass wool, an inboard cover, and an outboard cover. The two covers are stitched or cemented together at the blanket edges, along which there may be a trim strip and fastener tabs. The blankets vary widely in size and shape, each being tailored to fit its surroundings. Blankets that cover body frame intercostal webs have holes that match the holes in the intercostal webs. The holes allow air to circulate between the inboard side of the blanket and the sidewall lining.
C. Foamed plastic panels are on the bottom of the structural members just below the passenger cabin floor and along both sidewalls. The panels are cemented to the structural members. Fiberglass wool insulation blankets line the inner surfaces of the cargo compartment doors. The insulation blankets or panels are fastened to the skin by plastic studs or by cementing.
