## Discrepancy

WHEN THE LEADING EDGE SLATS WERE SELECTED FOR EXTENSION DURING APPROACH, THE AIRCRAFT ABRUPTLY ROLLED TO THE RIGHT AND THE -SLAT DISAGREE- LIGHT MOMENTARILY ILLUMINATED.  MAINTENANCE FOUND THE SLATS ON THE RIGHT HAND WING TO BE BINDING AND OPERATING SLOWER THAN THE LEFT SIDE, DUE TO EXCESS T-DUCT SIDE PLAY.  REPLACED THE RIGHT HAND T-DUCT, FUNCTIONALLY CHECKED IT, AND RETURNED THE AIRCRAFT TO SERVICE.
