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 adjacent component.
Ensure elbow assembly is properly
attached and secured to the tube.
Ensure the cyclic grip assy is properly
attached to the elbow assembly.
Ensure rubber grommet is installed
at wire bundle exit to prevent wire
chafing.
Ensure connector is 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.
Epoxy primer (E292) is flammable
and toxic. It can irritate skin and
cause burns. Use only with adequate
ventilation, away from heat and
open flame. Avoid contact with skin,
eyes, or clothing. In case of contact,
immediately flush skin or eyes for
at least 15 minutes. Get medical
