This tab is interconnected with the aileron system to automatically coordinate aileron
and rudder controls for simplified handling in the air. (It may be used as a rudder trim tab
to make the airplane trim in cruise.) This tab may be adjusted by changing to the position
of the tab cables where they attach to the aileron cables located just over the front doors
on the inside of the airplane.
Normally, the tab should be streamlined with the rudder
when the aileron and rudder controls are centered, using the centering spring for rigging
adjustments (See 7 above).
The tab travel is 48

right or left. Proper cable tension is 5 to 10 lbs.
CAUTION: Make sure tab is free at extreme aileron travel.
NOTE: The “Rudder Trim Control” on the instrument panel pulls on a spring attached to the
right rudder pedal. It is not connected to the tab on the rudder.
LUBRICATION
1. Main wheel bearings - Use aircraft quality bearing grease.
2. Hydraulic brake reservoirs - Use Texaco Aircraft Hydraulic Oil 15 conforming to MIL-H-5606E,
