6. Check bellcrank stops to ensure that bellcrank contact is made simultaneously, but still have cushion
before contacting control wheel stops. Maintain 0.030 to 0.040 clearance between sprocket pin and
adjustable stop bolts on models having adjustable tee bar stops.
7. Check complete system for operation and safety of turnbuckles, bolts, etc.
8. Install access plates and panels.
—NOTE—
When an out of trim condition persists despite all rigging
corrections, it is possible that trailing edge of aileron has been
used to move aircraft forward. This can result in a slight bulging
of aileron contour at trailing edge which will cause an out of rig
condition. This condition is very difficult to correct.
