Narrative:

Rudder position indicated approximately 3 1/2 - 4 degrees left. Required 4 degree right wing down aileron trim to maintain course. No warning lights at any time nor any other abnormal indications. Normal hydraulics, etc. Problem found by mechanic in slc to be binding of captain rudder pedal mechanism. Flight proceeded cvg to slc without incident. Supplemental information from acn 330586: problem was discovered to be in the captain's rudder pedal adjustment mechanism. Possibly the teleflex cable becoming worn and frayed.
