FLIGHT SAFETY PARTS
This is an installation critical flight
safety part. All aspects of its assembly
and installation must be ensured.
Ensure that all associated spacers,
washers, and bushings are installed.
At installation of bolt ensure that the
AN320-6 nut is tightened using proper
installation procedure to prevent
excess torque application to the
associated bellcrank hub bearings
thereby restricting free rotation of the
components.
Loose attachments within flight control
primary linkage will degrade aircraft
control. Missing components will
cause loss of control.

(85). Gap shall be 0.010 inch maximum.
