CES FITTINGS - DESCRIPTION AND OPERATION
____________________________________
1. General_______
Fittings are made of forged aluminum alloy, or aluminum alloy sheet. They are riveted to the structure.
2. Component Location__________________ (Ref. Fig. 001)
3. Description___________ Fittings make it possible to connect components to the structure, such as the attachment for the AFT cargo-compartment door.
Fittings are also installed in the main structure to connect the main structures together. The fittings are installed with sealant to prevent corrosion.

MISCELLANEOUS (EG : DRAINS) - DESCRIPTION AND OPERATION
_______________________________________________________
1.
General
_______ Drains are installed in the rear fuselage structure of the aircraft at or near to the lowest points in an area. The drains let water and condensation drain out so that they do not cause corrosion.

3. Description
___________ Drain valves are installed in the rear fuselage shell. When the cabin pressurizes, the valves, preset to operate when cabin pressurization reaches 2 psi (0.1378 bar), close to prevent loss of cabin pressure. As the cabin pressure decreases below the preset value (normally after the aircraft has landed), the valves open (under spring tension) to allow any water that has collected to drain away. You can remove the drain valves, for inspection or replacement, with an allen key from outside the aircraft. Drain valves are also installed in the door structure of the aft cargo compartment. In other structures (doors, door frames, stringers, brackets and fittings) holes are drilled at the lowest points to make sure that water and condensation drain to the drain valves.
