## Discrepancy

When the slats were extended the aircraft rolled and the "Slat Disagreement" light illuminated. After about 2 minutes the light extinguished and the aircraft flew normally. Landing at YYG was without incident. No mention of COM procedures. Maintenance found no discrepencies with either wing slat system. The right T-Duct was lubricated and will be replaced within 5 cycles. The aircraft has been returned to service.
