Task
Result
i. Move pilot cyclic stick (fig. 11–51) right until
it contacts right stop. Allow cyclic stick to
slowly return to center neutral position.
If cyclic stick does not return to center neutral
position, replace lateral (roll) feel spring cartridge
(TM 1-1520-238-23).
j. Move pilot cyclic stick left until it contacts left
stop. Allow cyclic stick to slowly return to
center neutral position.
If cyclic stick does not return to center neutral
position, replace lateral (roll) feel spring cartridge
(TM 1-1520-238-23).
k. Move pilot right directional pedal (fig. 11–58)
forward until it contacts stop. Allow
directional pedal to slowly return to center
neutral position.
If pedal does not return to center neutral position,
replace directional (yaw) feel spring cartridge
(TM 1-1520-238-23).
l. Move pilot left directional pedal forward until
it contacts stop. Allow directional pedal to
slowly return to center neutral position.
If pedal does not return to center neutral position,
replace directional (yaw) feel spring cartridge
(TM 1-1520-238-23).
m. Hold pilot cyclic stick FORCE TRIM switch
to FORCE TRIM REL.
If force trim does not disengage, go to
paragraph 11–14.
n. Move pilot cyclic stick forward approximately
3 or 4 inches. On pilot cyclic stick FORCE
TRIM switch, remove pressure from FORCE
TRIM REL position.
If cyclic stick does not remain in forward position,
replace longitudinal (pitch) magnetic brake
(TM 1-1520-238-23).
o. Hold pilot cyclic stick FORCE TRIM switch
to FORCE TRIM REL. Move pilot cyclic stick
slowly to center neutral position.
If force trim does not disengage, go to
paragraph 11–14.
p. Move pilot cyclic stick aft approximately 3 or
4 inches. On pilot cyclic stick FORCE TRIM
switch, remove pressure from FORCE TRIM
REL position.
If cyclic stick does not remain in aft position, replace
longitudinal (pitch) magnetic brake
(TM 1-1520-238-23).
q. Hold pilot cyclic stick FORCE TRIM switch
to FORCE TRIM REL. Move pilot cyclic stick
slowly to center neutral position.
If force trim does not disengage, go to
paragraph 11–14.
