4. Procedure
Subtask 25-62-42-210-055-A ** ON A/C NOT FOR ALL

A. Detailed Visual Inspection before the Installation

Offwing Escape-Slide Compartment ** ON A/C NOT FOR ALL

(1) Do a detailed visual inspection of the escape-slide enclosure door (8) (referred to in this procedure as the "enclosure door") for signs of damage.
(2) If the escape slide enclosure (7) 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 to measure the thickness of the external paint on the escape slide enclosure (7).
(b) Make sure that the thickness of the external paint on the escape slide enclosure (7) is not more than 0.33 mm (0.01 in.).
(3) Make sure that the enclosure door (8) is flush with the outer surface of the related escape slide enclosure (7).
(4) Make sure that all the three ball lock pins (18) are flush with the outer surfaces of the ball lock mechanisms (13).
(5) If the enclosure door (8) and the ball lock pins (18) are not in the correct position, you must replace the escape slide enclosure (7).

B. Installation of the Escape Slide Enclosure

Offwing Escape-Slide Compartment ** ON A/C NOT FOR ALL

(1) If necessary, apply a layer of external paint to the door of the escape slide enclosure (7).

NOTE: For the paint in the area of the escape-slide enclosure door, you can refer to the customized external painting and/or drawing. The structural repair manual also shows the specified type of materials you must use for different fuselage sections.

NOTE: If the enclosure door for the offwing escape slide comes painted with a layer of black conductive paint from the manufacturer, Airbus recommends to paint it before installation. You can use the escape slide enclosure without the external paint for some flights, but it is necessary to apply external paint during the next maintenance.

(2) Put the escape slide enclosure (7) in position.
(3) Tilt the top of the escape slide enclosure (7) outboard and hold the escape slide enclosure (7).
(4) Remove the PLUG-BLANKING from each disconnected line end.

CAUTION: USE A SECOND WRENCH TO APPLY COUNTER TORQUE TO THE UNIONS WHEN YOU DISCONNECT/CONNECT THE PNEUMATIC LINES FROM/TO THE UNIONS. IF YOU DO NOT OBEY THIS PRECAUTION, YOU CAN TWIST THE PNEUMATIC LINES AND CAUSE DAMAGE TO THEM.

(5) Connect the inflation hose (16) to the fuselage union (15).
(6) TORQUE the inflation hose (16) to between 3.2 and 3.0 m.daN (23.60 and 22.12 lbf.ft )

.
(7) Make sure that the elbow fitting of the inflation hose has a specified orientation for the correct installation. The specified orientation is at 5 degree angle to the top of the enclosure.
(8) Remove the CAP-BLANKING from each electrical connector and receptacle.
(9) Connect the emergency lighting electrical-connector (14).
(10) Close the escape slide enclosure (7) and install the studs (17).

CAUTION: DO NOT APPLY MORE THAN THE SPECIFIED TORQUE TO THE STUDS. IF YOU APPLY TOO MUCH TORQUE, THE STUDS CAN FALL OFF IN FLIGHT AND THE ESCAPE SLIDE WILL NOT BE CORRECTLY INSTALLED.

(11) TORQUE the studs (17) manually to between 3.0 and 2.7 m.N (26.55 and 23.89 lbf.in )

.
(12) Put the seal strips (9) and the seal attach plate (12) in position.
(13) Install the seal strips (9), seal attach plate (12), washers (11) and studs (10).
(14) TORQUE the studs (10) manually to between 3.0 and 2.7 m.N (26.55 and 23.89 lbf.in )

NOTE: If the parts are damaged or you cannot find them, you can send an order of the components as spare parts (Ref. AMM TASK 53-35-11-000-001) and (Ref. AMM TASK 53-35-11-400-001).

(15) Fill the space between the seal attach plate (12) and the escape slide enclosure (7) with Polysulfide Sealant-General Purpose Interfay - (Material No.06AAC1) .

(b) Make sure that the thickness of the external paint on the escape slide enclosure (9) is not more than 0.33 mm (0.01 in.).
(3) Make sure that the enclosure door (11) is flush with the outer surface of the related escape slide enclosure (9).
(4) If the enclosure door (11) is not in the correct position, it is necessary to replace the escape slide enclosure (9).
(5) Make sure that the enclosure door (11) is fully engaged and closed in the escape slide enclosure (9).
