D. Installation of the Rudder
(1)
Make sure that during the subsequent procedure, the correct identified components are installed at each connection.
(2)
Install the bushes (73),(74) in the hinge arm (63) at the location of the hinge No. 6 (RIB9 of the vertical stabilizer (1)). (Ref. Fig. 405/TASK 27-21-41-991-005)
(3)
Use the crane to lift the rudder (2) into position aft of the vertical stabilizer (1).
NOTE : There must be a mechanic at each of the hinges to align:
____
-
the axis of the hinge arms
-
the servo actuators 1025GM/2025GM/3025GM, with the hinge fittings on the rudder (2).
(4)
Move the rudder (2) to the left of the aircraft center line and then forward.
(5)
Prevent damage to the component interface and the adjacent area.
(a)
Make sure that there is sufficient clearance between the push-rod
(10)
of the transducer 42W, and the vertical stabilizer (1) and the rudder (2).
(b)
Make sure that there is sufficient clearance between the piston arms of the servo actuators 1025GM/2025GM/3025GM (35), and the vertical stabilizer (1) and the rudder (2).
(c)
Make sure that the edges of the support brackets are not damaged during the installation of the hinge arms.
(6)
Put the hinge arms (12),(50),(63),(90) in position at the brackets (11),(51),(64),(91) of the rudder (2).
(7)
Align the bolt holes in the hinge arms (12),(50),(63),(90) with their related bolt holes in the brackets (11),(51),(64),(91).
(8)
Connect the hinge No. 1 at RIB2 to the bracket (11) of the rudder (2). (Ref. Fig. 403/TASK 27-21-41-991-003)
(a)
Install the bush (25) in the bracket (11).
(b)
Install the locking plate (24) at the bracket (11).
(c)
Put the washer (15) on the bolt (23).
(d)
Install the bolt (23) through the connection of the bracket (11) and the hinge arm (12).
(e)
Install the bush (26) on the bolt (23) until the bush (26) goes into the bracket (11).
(f)
Install the slotted nut (27) on the bolt (23). Do not tighten the slotted nut (27) at this time.
(g)
Put the bonding jumper (31) in position and install the bolt (30) (Ref. TASK 20-28-00-912-004).
