(3) Measure and write down the number of degrees.
(4) Open the cargo door to a vertical position (Ref. AMM 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-ends (93) from the actuator attachment fitting.
(6) Open the cargo door with the crane to an opening angle of 136 deg. (Ref. AMM TASK 52-30-00-860-005).
(7) Install the 98D52307524000 STRUT-SUPPORT,CARGO DOORS to safety the opened cargo door.
(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.
(e) Install the bolts (85) with the washers (84) in the actuator attachment fitting.
(12) Remove the 98D52307524000 STRUT-SUPPORT,CARGO DOORS and disconnect the crane from the cargo door.
(13) Close and lock the cargo door (Ref. AMM TASK 52-30-00-860-002).
(16) If the door opening angle is less then 135 deg., adjust the length of the both door actuators as follows:
(b) Turn the piston rod (90) of both door actuators with the same quantity of rotation to get the correct the opening angle.
(c) Open the cargo door and make sure that the the door opening angle is between 135 deg and 136 deg.
(17) TORQUE the nut (92) to between 14.5 and 12.5 m.daN (106.93 and 92.18 lbf.ft ).
(18) Safety the nuts (92) and the locking devices (91) with14QFB1 Wire-Locking Dia: 0.8 mm CRES Nickel Alloy -
(19) TORQUE the nuts (82) to between 1.35 and 1 m.daN (119.47 and 88.50 lbf.in ) and safety it with the new AIPC 52-36-04-08-080 COTTER PINS (81) or AIPC 52-36-84-40-080 COTTER PINS (81).
(20) Install the bolts (86), the washers (87), the bonding jumpers (88) and the nuts (89) on the eye-end (93). (Ref. AMM TASK 20-28-00-912-802).
5. Close-up(1) Close the cargo door (Ref. AMM 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. AMM 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-ends (93) from the actuator attachment fitting.
(6) Open the cargo door with the crane to an opening angle of 136 deg. (Ref. AMM TASK 52-30-00-860-005).
(7) Install the 98D52307524000 STRUT-SUPPORT,CARGO DOORS to safety the opened cargo door.
NOTE: 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 (90) and make sure that they are mechanically locked (Ref. AMM TASK 52-30-00-860-001). NOTE: 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 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.
NOTE: Make sure that the bonding angle of the eye-end (93) points down.
(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.
NOTE: 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 98D52307524000 STRUT-SUPPORT,CARGO DOORS and disconnect the crane from the cargo door.
(13) Close and lock the cargo door (Ref. AMM TASK 52-30-00-860-002).
NOTE: Make sure that the two door actuators disengage at the same time.
(14) Measure the distance 'a' on the door actuator (90). NOTE: Make sure that the distance 'a' is more than 7.6 mm (0.2992 in.).
(15) Open the cargo door (Ref. AMM TASK 52-30-00-860-001) and make sure that the door opening angle is correct. (16) If the door opening angle is less then 135 deg., adjust the length of the both door actuators as follows:
NOTE: A full rotation (360 deg.) of the piston rod (90) increases or decreases the opening angle to 1 deg.
(a) Close the cargo door until it is in the vertical position. (b) Turn the piston rod (90) of both door actuators with the same quantity of rotation to get the correct the opening angle.
(c) Open the cargo door and make sure that the the door opening angle is between 135 deg and 136 deg.
(17) TORQUE the nut (92) to between 14.5 and 12.5 m.daN (106.93 and 92.18 lbf.ft )
. (18) Safety the nuts (92) and the locking devices (91) with
(19) TORQUE the nuts (82) to between 1.35 and 1 m.daN (119.47 and 88.50 lbf.in )
and safety it with the new AIPC 52-36-04-08-080 COTTER PINS (81) or AIPC 52-36-84-40-080 COTTER PINS (81). (20) Install the bolts (86), the washers (87), the bonding jumpers (88) and the nuts (89) on the eye-end (93). (Ref. AMM TASK 20-28-00-912-802).
