4.6.1.8 GRS 79
Inspect the GRS 79 unit, rack, and connector for corrosion or other defects. Check the
integrity of the SHIELD BLOCK ground attachments to the harness connector assembly
as well as the integrity of the individual shields and their attachment. Inspect wiring
harness for chaffing.
4.6.1.9 GSA 80 Pitch and Yaw Servo and GSM 86 Servo Gearbox
Inspect the servo, servo mount, connector, and support structures to ensure that no
corrosion, chaffing, cracks, or other defects exist. Check the servo control cable to
ensure no fraying, corrosion, or other damage exists. If the condition of the cable is
questionable, replace it with a new one.
Ensure the cable is correctly attached to the pulley and check the tension of the servo
control cable. Have an assistant manually move the elevator from stop to stop and
visually monitor the servo, servo mount, and control surface cabling. Ensure there is no
binding in the control cabling, and the capstan pulley rotates freely.
Inspect the servo wiring and ensure no chaffing, wear, or other damage exists.
4.6.1.10 GSA 81 Pitch Trim Servo and GSM 86 Servo Gearbox
Inspect the servo, servo mount, connector, and support structures to ensure that no
corrosion, chaffing, cracks, or other defects exist. Check the servo control chain to
ensure no link deformation, corrosion, or other damage exists. If the condition of the
chain is questionable, replace it with a new one.
Ensure the chain is correctly engaged to the sprockets. Check the rigging of the servo
control chain. Have an assistant manually move the elevator trim wheel from stop to stop
and visually monitor the servo, servo mount, and control chain movement. Ensure there
is no binding in the control chain and the capstan sprockets turn freely.
Inspect the servo wiring and ensure no chaffing, wear, or other damage exists. Replace
the access panels if no other maintenance is to be performed.
4.6.1.11 GSA 81 Roll Servo
Gain access to the roll servo gearbox and move the control wheel full travel (left and
right) while observing the gearbox capstan and roll servo cables using an inspection
mirror (or equivalent) and adequate lighting.
Verify the roll servo cables are properly routed, are not touching any of the capstan
retaining pins, and are not interfering with any other structure. Check for any signs of
fraying or damage to the roll servo cables.
Listen for indication of roll servo cables contacting any retaining pins or other structure. If
either roll servo cable is found to contact any capstan retaining pin or other structure, or if
either roll servo cable shows any signs of fraying or damage, the roll servo cable(s) must
be replaced before further flight.
