## Discrepancy

WHEN SLATS WERE DEPLOYED AT 250 KTS, THE AIRCRAFT ROLLED TO THE RIGHT AND THERE WAS NO BLUE SLAT EXTEND LIGHT.  CREW CYCLED THE SLATS BACK UP NORMALLY, RE-DEPLOYED AND THE AIRCRAFT ROLLED AGAIN.  AFTER A FEW SECONDS THE BLUE LIGHT ILLUMINATED AND THERE WAS LESS TENDENCY TO ROLL.  LANDING AT MCI WAS UNEVENTFUL.  MAINTENANCE FOUND THE LEFT T-DUCT SLOW.  REPLACED THE LEFT -T- DUCT.  AIRCRAFT RETURNED TO SERVICE.
