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 airframe.
Ensure that all bushings are properly
installed (including orientation) in the
output clevis of the bellcrank.
Ensure bellcrank hub bearings are
serviceable and properly installed.
Ensure proper attaching hardware
(impedance 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 components will
cause loss of control.
73.
Position socket (128) in bellcrank (112), tube
(133) up and forward.
74.
Install bolt (134), head left, two washers (135 and
136) and nut (137) in bellcrank (112). Remove
tag from socket (128).
75.
Torque nut (137) to 85 to 125 inch-pounds.
Install cotter pin (138).
76.
Check bolt (134). 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 75.
