Piper Arrow IV Turbo Maintenance Manual page 254

5. Check the bellcrank stops to assure that the bellcrank contact is made simultaneously, but still have
cushion before contacting the control wheel stops. Maintain .030 to .040 clearance between sprocket pin and
adjustable stop bolts on models having adjustable tee bar stops.
6. Check complete system for operation and safety of turnbuckles, bolts, etc.
7. Install access plates and panels.
When an out of trim condition persists despite all the rigging
corrections that can be made, there is a possibility that the
trailing edge of the aileron has been used to move the aircraft
forward. This can result in a slight bulging of the aileron contour
at the trailing edge which will cause an out of rig condition that
is very difficult to correct.
