safety part. All aspects of its assembly
and installation must be ensured.
Ensure that both machined rod ends
attached to the link are secure.
Ensure that both rod end jam nuts are
installed and torqued.
Ensure that the rivet through the fixed
rod end bearing is secure.
Ensure painted band on control rod
faces towards pilot. (AFT)
Ensure rod end bearing faces aft
attaching to socket assembly.
At installation of this component,
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.
