Subtask 25-62-47-860-051-A ** ON A/C NOT FOR ALL

A. Aircraft Maintenance Configuration
(1) Make sure that you obeyed the special precautions before you work on the escape slide system(s) (Ref. AMM D/O 25-62-00-48).
(2) On the overhead panel, on SIGNS panel 25VU, make sure that the EMER EXIT LT pushbutton switch is released (the OFF legend is on) (Ref. 23-73-00).

WARNING: MAKE SURE THAT YOU TURN THE RELEASE LEVER BACK TO THE DISARMED POSITION. IF YOU DO NOT, THE ESCAPE-SLIDE RELEASE SYSTEM STAYS ON. IF YOU THEN CONNECT AN INFLATION RESERVOIR TO THE SYSTEM, THE INFLATION RESERVOIR WILL IMMEDIATELY OPERATE. THIS CAN CAUSE INJURY TO PERSONNEL AND/OR DAMAGE TO EQUIPMENT.

(3) Make sure that the operating striker lever of the door damper and the emergency operation cylinder is in the DISARMED position (Ref. AMM TASK 52-22-00-860-003).
(4) Make sure that the slide control handle is in the DISARMED position and the 98A52107632000 PIN - SAFETY SLIDE is installed.
(5) Close the emergency exit doors and make sure that are locked (Ref. AMM TASK 52-22-00-410-001) or (Ref. AMM TASK 52-22-00-410-002).
(6) Make sure that a WARNING NOTICE(S) are in position to tell persons not to open the emergency exit doors.
(7) For the escape slide enclosure below left and/or right door 3:
(a) Make sure that the slat/flap control lever is set to position 0 (Ref. AMM TASK 27-50-00-866-009).
(b) Make sure that the 98D27803000000 LOCKING TOOL-FLAP SLAT LEVER,INT. POSITION or 98D27803500001 LOCKING TOOL ZERO POS is installed on the flap/slat control lever.
(c) Make sure that a WARNING NOTICE(S) is on the slat/flap control lever to tell persons not to operate the flaps.
(8) Put an ACCESS PLATFORM 2M (6 FT) in position on the escape slide enclosure.

B. Preparation for Installation

Escape Slide Enclosure ** ON A/C NOT FOR ALL

(1) Make sure that the placard CAUTION ESCAPE SLIDE is installed on the new escape slide enclosure (5).
(2) If the inflation reservoir is removed, make sure that the pressure seal caps are installed on the disconnected hose assemblies of the inflation reservoir (Ref. AMM TASK 25-62-49-000-001).
(3) If the escape slide enclosure (5) is painted again, do the steps that follow:

CAUTION: MAKE SURE THAT THE PAINT THICKNESS ON EXTERNALLY INSTALLED SLIDES IS NOT MORE THAN 0.33 MM. IF THE PAINT LAYER IS THICKER, THERE IS A RISK OF DAMAGE TO THESE COMPONENTS IF A LIGHTNING STRIKE OCCURS.

(a) Use the GAGE-THICKNESS, PAINT BORER 518 and measure the thickness of the external paint on the escape slide enclosure (5).
(b) Make sure that the thickness of the external paint on the escape slide enclosure (5) is not more than 0.33 MM (0.01 IN.).
(4) Do a check of the aircraft enclosure recess and the attach panel (3).
(5) Make sure that the blow out door (14) is flush with the outer surface of the escape slide enclosure (5).
(6) If the blow out door (14) is not in the correct position, replace the escape slide enclosure (5).
(7) Make sure that the blow out door (14) is fully engaged and closed in the escape slide enclosure (5).
(8) Make sure that the location pin hole (12) which is in the attach panel (3) aligns with the location pin (13) which is on the aircraft enclosure recess.

NOTE: The left and right escape slides of doors 2 and 3 are not interchangeable. The location pin (13) which is installed on the aircraft enclosure recess prevents the incorrect installation of the escape slide enclosure (5).

(9) Do a visual inspection of the door lock mechanism on the blow out door (14).

NOTE: The attach panel (3) contains the blow out door (14). The door lock mechanism holds the blow out door (14) in the closed position.

(10) Examine the catches of the blow out door (14). Make sure that the ball lock pins (15) are flush with the door catch inserts (16) and the blow out door (14).
(11) Make sure that the ball lock pins (15) of the escape slide enclosure (5) are clean and that there is no paint on them.
(12) If the ball lock pins (15) are not in the correct position, replace the escape slide enclosure (5).

(2) If the inflation reservoir is removed, make sure that the pressure seal caps are installed on the disconnected hose assemblies of the inflation reservoir (Ref. AMM TASK 25-62-49-000-001).
(3) If the escape slide enclosure (4) is painted again, do the steps that follow:

(a) Use the GAGE-THICKNESS, PAINT BORER 518 and measure the thickness of the external paint on the escape slide enclosure (4).
(b) Make sure that the thickness of the external paint on the escape slide enclosure (4) is not more than 0.33 MM (0.01 IN.).
(4) Do a check of the aircraft enclosure recess and the escape slide enclosure (4).
(5) Make sure that the blow out door (6) is flush with the outer surface of the escape slide enclosure (4).
(6) If the blow out door (6) is not in the correct position, replace the escape slide enclosure (4).
(7) Make sure that the blow out door (6) is fully engaged and closed in the escape slide enclosure (4).
(8) Make sure that the location pin hole (5) which is in the escape slide enclosure (4) aligns with the location pin (3) which is on the aircraft enclosure recess.

NOTE: The escape slides of the left and right side doors are not interchangeable. The location pin (3) which is installed on the aircraft enclosure recess prevents the incorrect installation of the escape slide enclosure (4).

(9) Make sure that the three ball lock pins (10) are fully engaged and that you cannot see the red O-rings (11) of the three ball lock pins (10).
