## Discrepancy

THE LT MLG UNSAFE LIGHT REMAINED ILLUMINATED AFTER GEAR EXTENSION ON APPROACH.  ABNORMAL PROCEDURES WERE COMPLIED WITH AND THE EMERGENCY GEAR EXTENSION LEVER WAS PULLED.  A TOWER FLY-BY WAS PERFORMED AND THE GEAR WAS CONFIRMED DOWN.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE LT MLG DOWNLOCK SWITCH CANNON PLUG DIRTY.  THE PLUG WAS CLEANED.  A SYSTEM TEST ON THE LANDING GEAR LIGHTS CHECKED GOOD IAW MM 32-60-1, PAGE 201.
