747-400 MAINTENANCE MANUAL
FLOOR MOUNTED ESCAPE SLIDE UNIT - REMOVAL/INSTALLATION
______________________________________________________
1. General_______
A. The floor-mounted escape slide may be removed and installed as a complete unit including the escape slide pack and packboard, the stored gas bottle, and the base and chute assembly. Removal of the complete unit is accomplished by unlatching the base shear plunger, removing the stop from the forward end of the inboard track, moving the unit forward or aft (approximately 0.90 inch) and lifting it up clear of the floor tracks. However, because the escape slide pack weighs approximately 167 pounds and the stored gas bottle approximately 45 pounds, it is recommended that the assembly be removed in three stages: the stored gas bottle, the escape slide pack, and the base and chute assembly.
B. This procedure contains two tasks:
(1)
A task to remove the escape slide assembly
(2)
A task to install the escape slide assembly.
