## Discrepancy

WHEN SLATS WERE SELECTED TO EXTEND, THE AIRCRAFT ROLLED TO THE LEFT AND THE 'SLAT DISAGREE' LIGHT ILLUMINATED.  COMPLIED WITH COM PROCEDURES AND THE SECOND ATTEMPT HAD THE SAME RESULTS.  THE SLAT DISAGREE LIGHT DID NOT EXTINGUISH.  FLIGHT LANDED UNEVENTFULLY AT GRR WITH THE SLATS RETRACTED.  MAINTENANCE LUBRICATED THE RIGHT 'T' DUCT, EXERCISED THE SLAT EXTENSION SYSTEM, AND ALL CHECKED NORMAL.  THE AIRCRAFT RETURNED TO SERVICE.
