## Discrepancy

CLE - FL2636 - CAPTAIN STATED THAT THE NR 4 LEADING EDGE SLAT AMBER LIGHT ILLUMINATED ON INITIAL APPROACH.  CREW CONFIRMED VISUALLY THAT THE SLAT WAS NOT FULLY EXTENDED AND DECLARED AN EMERGENCY.  AFTER ABOUT 5 MINUTES AT FLAPS 15, THE SLAT DID FULLY EXTEND.  FLIGHT LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE REMOVED AND REPLACED THE NR 4 LEADING EDGE SLAT ACTUATOR PER MM 27-81-41.  OPERATIONAL CHECK AND LEAK CHECK GOOD.  (M)
