(c) Hold the first officer’s control wheel at the neutral position.
(d) Turn the captain’s control wheel clockwise to 75 degrees from the neutral position.
1) Make sure the aileron spring cartridge [17] extends while you turn the control wheel.
2) Make sure the maximum breakout force is 436 pound-inches (49.2 newton-meters) or
67 pounds (298.0 newtons).
NOTE: The ‘‘breakout’’ force occurs when the captain’s control wheel starts to move
with the first officer’s control wheel hold in the neutral position.
3) Make sure the maximum force at 75 degrees is 676 pound-inches (76.3 newton-meters)
or 104 pounds (462.6 newtons).
(e) Turn the captain’s control wheel counterclockwise to 75 degrees from the neutral position.
1) Make sure the aileron spring cartridge [17] compresses while you turn the control
wheel.
2) Make sure the maximum breakout force is 436 pound-inches (49.2 newton-meters) or
67 pounds (298.0 newtons).
3) Make sure the maximum force at 75 degrees is 676 pound-inches (76.3 newton-meters)
or 104 pounds (462.6 newtons).
(f) Turn and hold the first officer’s control wheel clockwise at 80 degrees from the neutral
position.
(g) Turn the captain’s control wheel counterclockwise until the transfer mechanism stops
touch.
1) Make sure the captain’s control wheel turns a minimum of 138 degrees from the
starting position.
2) Make sure the transfer mechanism can move freely when you turn the control wheel.
(h) Turn and hold the first officer’s control wheel counterclockwise at 80 degrees from the
neutral position.
(i) Turn the captain’s control wheel clockwise until the transfer mechanism stops touch.
1) Make sure the captain’s control wheel turns a minimum of 138 degrees from the
starting position.
2) Make sure the transfer mechanism can move freely when you turn the control wheel.
(j) Turn and hold the captain’s control wheel clockwise at 80 degrees from the neutral
position.
(k) Turn the first officer’s control wheel counterclockwise 130 degrees from the starting
position (80 degrees clockwise).
1) Make sure the aileron spring cartridge [17] extends and can move freely while you turn
the control wheel.
2) Make sure the maximum force to turn the captain’s control wheel is 1000 pound-inches
(112.9 newton-meters) or 154 pounds (684.0 newtons).
(l) Turn and hold the captain’s control wheel counterclockwise at 80 degrees from the neutral
position.
(m) Turn the first officer’s control wheel clockwise 130 degrees from the starting position (80
degrees counterclockwise).
