## Discrepancy

DURING SLAT RETRACTION AFTER TAKEOFF, THE AIRCRAFT ROLLED TO THE LEFT ACCOMPANIED BY THE SLAT DISAGREEMENT LIGHT.  COMPLIED WITH COM PROCEDURES WHICH REQUIRED THE SLATS TO BE EXTENDED AND THAT NEUTRALIZED THE UNCOMMANDED ROLLING TENDENCY.  FLIGHT RETURNED TO MSP AND LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE REPLACED THE LEFT -T- DUCT AND AIRCRAFT RETURNED TO SERVICE.
