## Discrepancy

THE LT MLG GREEN LIGHT DID NOT ILLUMINATE FOR SEVERAL MINUTES WHEN GEAR WAS EXTENDED ON APPROACH INTO IAH.  THE AIRCRAFT LANDED WITHOUT INCIDENT. WHEN MAINTENANCE PERFORMED A GEAR SWING THE LT MAIN GEAR DID NOT EXTEND, BUT MANUAL EXTENSION WAS GOOD.  THE LT MLG UPLOCK ACTUATOR  WAS REMOVED AND REPLACED IAW MM 32-32-41.  IN ADDITION, THE GEAR WAS LUBRICATED AND THE LT MLG DOWNLOCK SENSOR WAS CHECKED AND FOUND WITHIN LIMITS.  AN ADJUSTMENT/TEST WAS PERFORMED IAW MM 32-32-00 AND ALL OPERATION CHECKED GOOD.
