## Discrepancy

UPON SLAT EXTENSION, THE AIRCRAFT ROLLED TO THE RIGHT AND THE BLUE SLAT EXTEND LIGHT DID NOT ILLUMINATE. CREW CYCLED SLATS ONCE MORE WITH SAME RESULTS. FOLLOWED COM PROCEDURES AND LANDED UNEVENTFULLY WITHOUT SLATS AT FSD. MAINTENANCE INSPECTED AND CHECKED THE SLATS, OPERATED USING EACH HYDRAULIC SYSTEM INDIVIDUALLY AND BOTH SLATS WORKED NORMALLY. LUBRICATED THE 'T' DUCTS. AIRCRAFT RETURNED TO SERVICE.
