## Discrepancy

INSPECTION FOUND THE LT WING NR 1 LEADING EDGE SLAT DENTED IN SEVERAL PLACES AFTER AIRCRAFT ARRIVED.  THE DENTS WERE CAUSED BY IMPACT FROM ICE.  MAINTENANCE FOUND THE NR 2 WATER TANK SYSTEM LEAKING AT SERVICE PANEL.  THE DRAIN T-HANDLE COULD NOT BE STOWED AND WAS BINDING.  THE NR 2 TANK OVERFLOW VALVE ASSEMBLY WAS FOUND TO BE STICKING, AND NOT ALLOWING THE FILL/DRAIN VALVE ASSEMBLY TO CLOSE.  THE OVERFLOW VALVE WAS REMOVED AND REPLACED, LEAK AND OPERATIONAL CHECKS WERE GOOD.  THE NR 1 LEADING EDGE SLAT WAS REMOVED AND REPLACED IAW MM 27-80-01 CONFIGURATION 1 PAGE 401.
