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 and mounting to
the pallet assembly.
Ensure actuator mounting supports
are properly installed including safety
wire between mounting bolts.
Ensure proper torque values are
utilized when installing the actuator
supports to pallet mounting hardware.
Ensure proper attaching hardware
(self retaining type bolt, nut, and
washers) is installed including
verification of bolt head orientation,
torque, and installation of cotter pins.
Loose attachments within flight control
primary linkage will degrade aircraft
control. Missing componets will cause
loss of control.
4.
Position actuator (1) on pallet (7), arm (8) inboard
and supports (2 and 3) to pallet. Install four bolts
(9), and four washers (10). Torque bolts to 45
inch-pounds.
5.
Remove nut (11), two washers (12 and 13), and
bolt (14) from spring (15).
6.
Position spring (15) in arm (8). Install bolt (14),
two washers (13 and 12), and nut (11).
6.1.
Torque nut (11) to 30 inch-pounds. If necessary,
continue tightening to align cotter pin holes. Do
not exceed 45 inch-pounds. Install cotter pin
(16).
7.
Check bolt (14). Bolt shall not rotate with torque
less than 10 inch-pounds. There shall be no
axial looseness. If bolt rotates or is loose, add
washer under nut and repeat step 6.
8.
Connect connector (17) to receptacle (18) of
actuator (1). Remove tag.
