## Discrepancy

LT MLG DOWN INDICATION FAILED TO ILLUMINATE WHEN GEAR WAS EXTENDED. PERFORMED AFM ABNORMAL PROCEDURES. DECLARED EMERGENCY, BLEW GEAR DOWN AFTER A SHORT TIME, GREEN DOWN INDICATION DID ILLUMINATE AND AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE STAFF REPLACED GEAR ACTUATOR. OPS CHECKED GOOD AND AIRCRAFT WAS RETURNED TO SERVICE.
