## Discrepancy

IAH - FLIGHT 2365, THE CREW REPORTED A LANDING GEAR AIR GROUND FAIL AND E1-2 TR DISAGREE MESSAGES IN CRUISE.  WHEN EXTENDING THE LANDING GEAR ON APPROACH, ALL MESSAGES CLEARED AND THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED THE AIRCRAFT AND REMOVED AND REPLACED THE NOSE LANDING GEAR AIR/GROUND PROXIMITY SWITCH.  OPERATIONALLY TESTED WITH NO DEFECTS, AND THE AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE.
