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
adjacent bellcrank assembly.
Ensure that all bushings are properly
installed (including orientation) in
each input and 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.
