Hi Bruce;
What’s the problem? Slow? Control wheel is cocked in straight and level flight? Can’t trim for straight and level flight?
These are the most common problems.
The rigging procedure involves setting the nose wheel and rudder pedals in accordance with the service manual, and setting the rudder trim to neutral. All control surfaces travels (flaps, ailerons, stabilator, and pitch trim tab) and cable tensions should be checked and set to book values.
After everything is set to book values, then the aircraft should be flown with its “normal load” at the most common power settings.
It should be pretty close at that point. If one wing is “heavy” then the book suggestion is to lower the flap on the heavy wing a few degrees until straight and level flight is obtained.
A competent independent shop should be able to do these inspections and adjustments. The most common rigging problem I see occurs when a shop doesn’t take the time to rig all the systems but does a quicky job.
All the procedures and information is in the service manual for your airplane.
Unfortunately, I can’t track all the “good” shops across the country so I can’t point you at a shop that I know is good at rigging.
Let me know what you come up with and if I can help.
Steve
