## Discrepancy

THE LT MLG UNSAFE LIGHT ILLUMINATED AFTER TAKEOFF FROM IAH.  THE CREW VERIFIED THAT THE LT MLG HAD NOT RETRACTED.  THE CREW PLACED THE GEAR HANDLE IN THE EXTENDED POSITION AND GOT THREE GREEN LIGHTS.  THE AIRCRAFT WAS RETURNED TO IAH WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE LT MLG TRUNNION PIN BROKEN IN TWO AND CORRODED.  THE LT MLG TRUNNION PIN WAS REMOVED AND REPLACED.  AN FCD WILL BE ISSUED TO INSPECT THE FLEET LG TRUNNION PINS.
