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 transmission cover.
The yoke assembly is machined
from a titanium forging or billet and
therefore requires special handeling.
Verify required flange and slip
bushings are properly installed in
each clevis of the yoke assembly.
Ensure hub bearings and spacer are
properly installed and serviceable.
At installation of the yoke shaft, ensure
slip bushing is properly installed in the
aft lug of the transmission cover yoke
mounting clevis.
For all mating components 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.
Ensure special countersunk washers
are installed properly under the head
of self retaining bolts. Countersink
must face towards head of bolt.
Loose attachments within flight control
primary linkage will degrade aircraft
control. Missing components will
cause loss of control.
Support shaft must be installed dry.
7.
Insert support shaft (9), heed aft, through access
hole (14) in bulkhead (15). Install shaft in mount
(10) and yoke (1). Use rawhide mallet. Make
sure threads of shaft are dry.
