INTERIOR EQUIPMENT SUPPORTS AND FITTINGS - DESCRIPTION AND OPERATION
____________________________________________________________________
1. General_______
A. Interior equipment supports and fittings are those attachments for the seats, lavatory modules, galleys, and other components that are not electrical or electronic equipment.
2. Seat Attachment Fittings________________________
A. Eight seat tracks extend nearly the full length of the main deck. Only in the forward and aft ends is the quantity of seat tracks reduced to accommodate the tapered area of the fuselage. Four seat tracks in the upper deck area extend from the forward to the aft end. The seat tracks are attached to the tops of the floor beams or except over the wing center section where they are integral with the floor beams. The seat tracks allow seats in the upper deck to be installed at any of the locations provided in the tracks. The tracks in the upper deck also support the lavatory modules, galleys, and other equipment.
B. All flight crew seats are attached to special seat tracks which provide for movement of the seats in directions required for access or adjustment.
3. Miscellaneous Equipment Attach Fittings_______________________________________
A. Fittings are provided on the fuselage structure for attachment of air conditioning equipment, lavatory equipment, water tanks, safety equipment (slides, ladders, etc.), and oxygen equipment.
