Components on the Outside of the Door
These are the components on the outside of the door:
*
Component access panel (8)
*
Lift/latch manual drive socket
*
Sling attach point (3).
Training Information Point
The access panels give access to failed components if the cargo door is not open.
The lift/latch manual drive socket lets you open the door manually.
The sling attach points let you use a sling to lift the door for removal and replacement. It also lets you lift the door open if the lift mechanism fails.

AFT SMALL CARGO DOOR SYSTEM -AFT SMALL CARGO DOOR
Purpose
The door closes the external access to the aft cargo compartment.
Physical Description
The door is a plug type.
There are two pressure hook stops along the top of the door.
Two guide rollers and ten stop pins are on each side of the door.
There are two pressure hooks along the bottom of the door.
Functional Description
The guide rollers move in guide tracks on the door cutout. They guide the vertical movement of the door into and out of the plug position.
The hook stops on the top of the door mate with hooks on the top of the door cutout. The hooks on the bottom of the door mate with hook stops on the bottom of the door cutout.
The twenty stop pins on the sides of the door mate with twenty stop pads and ten ditching stops on the sides of the door cutout. The stop pins transmit pressurization loads on the door to the stop pads on the cutout. Ten of the stop pin fittings on the door will transmit loads to ditching stops on the cutout if a ditching occurs.

AFT SMALL CARGO DOOR SYSTEM -VENT DOOR AND VENT DOOR CAM
Purpose
The vent door has these functions:
*
Releases remaining pressurization when you open the cargo door
*
Prevents the door from lifting if there is too much pressure to let it open safely.
The vent door cam has these functions:
*
Releases the vent door when the cargo door begins to unlatch
*
Stops rotation of the lift/latch torque tube if residual pressurization is too high for safe operation of the cargo door.
Location
The vent door is on the upper, forward part of the cargo door above the lift/latch torque tube.
The vent door cam is on the lift/latch torque tube.
Physical Description
A hinge shaft connects the vent door to the cargo door. A torsion spring that is around the shaft, connects to the door. A push rod connects the vent door to the vent door crank that works with the vent door cam.
Functional Description
When the cargo door is closed and latched, the cam pushes against the crank. The push rod which attaches to the crank holds the vent door closed. When the lift/latch torque tube begins to rotate to unlatch the door, the cam lets the lever move. The spring on the hinge shaft opens the vent door.
