_________
(Ref. Fig. 510/TASK 52-31-11-991-015) Subtask 52-31-11-820-059
A. Adjustment of the Door Opening Angle
(1)
Close the cargo door (Ref. TASK 52-30-00-860-001).
(2)
Hold the clinometer in position at the actuator attachment fitting with the cargo door in the locked position.
(3)
Measure and write down the number of degrees.
(4)
Open the cargo door to a vertical position (Ref. TASK 52-30-00-860-001).
(5)
Disconnect the eye-ends (93) of both door actuator (90) as follows:
(a)
Remove the nuts (89), the washers (87), the bolts (86) and the bonding jumpers (88) from the eye-end (93).
(b)
If necessary, remove and discard the cotter pin (81) from the bolt (85).
(c)
Remove the nut (82) and the washers (83) from the bolt (85).
(d)
Support the door actuators (90) and remove the bolt (85) with the washer (84) from the door fitting.
(e)
Disconnect the eye-end (93) from the actuator attachment fitting.
(6)
Open the cargo door with the crane to an opening angle of 136 deg (Ref. TASK 52-30-00-860-005) .
(7)
Install the SUPPORT STRUT - CARGO DOORS (98D52307524000) to safety the opened cargo door.
-Make sure that the length of each support strut is correctly adjusted so that the related pip pin goes in freely into the cargo door.
(8)
Carefully extend the pistons of the door actuators and make sure that they are mechanically locked (Ref. TASK 52-30-00-860-001).
-Make sure that the pistons of the door actuators do not damage the aircraft structure.

(9) Make sure that the bore of the eye-ends (93) are align with the bore
of the actuator attachment fitting.
NOTE : The bores are align if the bolt (85) goes in freely.
____
(10)
If not, adjust the length of the door actuators (90) as follows:
(a)
Cut and remove the lockwire from the locking devices (91) and the nuts (92).
(b)
Loosen the nuts (92).
(c)
Turn the eye-end (93) until you can install the bolt (85) freely.
-Make sure that the bonding angle at the eye-end (93) show downside.
(d)
If you cannot install the bolt (85) freely, turn the piston rod
(90) as required to install the bolt (85) freely (fine adjustment).
(e)
Install the bolts (85) with the washers (84) in the actuator attachment fitting.
-Make sure that the bolt (85) goes in freely.
(11)
Install the washers (83) and the nuts (82) on the bolt (85).
(12)
Remove the SUPPORT STRUT - CARGO DOORS (98D52307524000) and disconnect the crane from the cargo door.
(13)
Close and lock the cargo door (Ref. TASK 52-30-00-860-002).
-Make sure that the two door actuators disengage at the same time. 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320飞机维护手册 AMM DOORS 舱门4(62)
