Adjustment of the Release Travel ** ON A/C NOT FOR ALL

(1) Make sure that the related door is correctly closed (Ref. AMM TASK 52-22-00-410-001).
(2) Make sure that the door damper is in this condition:

The release lever (63) of the door damper is fully retracted in its safetied position.
The percussion mechanism of the door damper is blocked with the related 701-2978000 PIN-SAFETY, PAX DOOR DAMPER (69).

(3) Make sure that the inflation reservoir is in this condition (Ref. AMM TASK 52-22-00-010-001):

Its operation valve is safetied with the related lock pin.
Its release cable is disconnected from the release lever.

(4) Measure the distance "U" between the lower edge of the release lever (63) and the top of the stop bolt (64) as follows:
(a) Pull up the inboard handle until the door lifts but do not open it at this stage.
(b) Set the slide control handle to the ARMED position.
(c) Loosen the knurled screw (62) and carefully extend the release lever (63) until it touches the stop bolt (64).
(d) Put a mark on the stop bolt (64) to show the position of the lower edge of the release lever (63).

NOTE: It is necessary to use a PENCIL - SHARP to make the mark on the stop bolt (64).

(e) Retract the release lever (63) and safety it with the knurled screw (62).
(f) Measure the distance between the pencil mark and the top of the stop bolt (64):

NOTE: The dimension must be between 5.5 mm (0.2165 in.) and 6.5 mm (0.2559 in.).

(5) If the distance "U" is out of tolerance, adjust the position of the stop bolt (64) as follows:
(a) If necessary, bend the tab washer (66) to release the adjustment nut (65).

NOTE: If you must do this, replace the AIPC 52-22-22-06-170 TAB WASHER (66).

(b) Loosen the jam nut (68) and the adjustment nut (65).
(c) Turn the stop bolt (64) as necessary until the distance "U" is correct.
(d) Tighten the adjustment nut (65) and the jam nut (68).
