moved. DO NOT COMPRESS SPRINGS.

mension between steering arm assembly and bolt
• hole as illustrated in figure 5 -9 and tighten jam nuts.
h. Adjust steering tube clevises to align with rod
end bearings.
NOTE
Extend steering tubes to seat rods against

j. Safety cable clevises and install all parts re-
moved for access.
NOTE
On aircraft WITHOUT rudder trim tab, a
flight test may determine the need for
rigging rudder slightly off-center. Such
correction should be made by tightening
one rudder cable at clevis and loosening
the opposite one an equal amount, thus
keeping nosewheel steering system and
rudder pedals aligned while rudder is shift-
ed minutely. DO NOT attempt to rig rud-
der by adjusting nosewheel steering system.
On aircraft WITH rudder trim tab, flight
test aircraft to determine if ground adjust-
ment of fixed trim tab is necessary. DO
NOT rig rudder "off-center" unless trim
tab does not provide adequate correction.
IWARNING'
Be sure rudder moves in correct direction
when operated by pedals.
