m. Move pilot cyclic stick aft until it contacts
stop. Position rigging fixture to align
longitudinal AFT pointer with center point of
alignment tool. Verify that center point of
alignment tool is between the MAX and MIN
marks on rigging fixture longitudinal AFT
pointer (fig. 11–80).
If center point of alignment tool lies outside the MAX
and MIN marks on rigging fixture longitudinal AFT
pointer, perform rigging of longitudinal cyclic stick
stops (TM 1-1520-238-23).
If cyclic stick stops are rigged correctly, replace
longitudinal servocylinder (TM 1-1520-238-23).
