Bushings must be in swashplate and
yoke before installing bolts; otherwise,
damage to components will result.
NOTE
Positive retention bolts are installed
in flight control connections. These
bolts are self-retaining and require a
special nut and torque (Task 1-13).
1.
Remove nut (1), washer (2), and bolt (3) from
swashplate (4) and connecting link rod end (5).
2.
Remove nut (6), washer (7), and bolt (8) from
swashplate (4).
3.
Apply antiseize compound (E75) to bushing (9)
on bolt (8). Keep compound off threads of bolt.
Wear gloves (E184.1) and goggles.
FLIGHT SAFETY PARTS
This is an installation critical flight
safety part. All aspects of its assembly
and installation must be ensured at
each joint connection including its
mounting to the swashplate and yoke
assembly.
Ensure locking tab washer is facing in
the proper direction.
Ensure wire bundle is routed so as not
to interfere with flight control system
motions.
After applying nut torque, ensure
locking tab washer is lockwired to the
jam nut per BAC5018.
Ensure proper attaching hardware
(impedance type bolt, nut, and
washers) is installed including
verification of bolt head orientation,
torque, and installation of cotter pins.
Ensure special countersunk washers
are installed properly under the head
of self retaining bolts. Countersink
must face towards head of bolt.
Loose attachments within flight control
primary linkage will degrade aircraft
control. Missing components will
cause loss of control.
4.
Position rod end (10) of actuator (11) in
attachment lug (12) of swashplate (4). Actuator
motor (13) must face aft.
5.
Install bolt (8), head forward, through swashplate
lug (12) and actuator rod end (10). Install
washer (7) and nut (6). Torque nut to 660 to 780
inch-pounds. Do not exceed 1400 inch-pounds
for cotter pin alignment. Install cotter pin (14).
6.
Connect actuator connector (15) to receptacle
(16).
7.
Remove nut (17), washer (18), and bolt (19) from
yoke (20).
