## Discrepancy

IAH - FLIGHT 2010, THE CREW REPORTED A LANDING GEAR AIR/GRND FAIL MESSAGE ON EICAS AFTER TAKEOFF.  THE AIRCRAFT RETURNED TO IAH WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE REMOVED AND REPLACED THE RIGHT MAIN LANDING GEAR SHOCK ABSORBER PROXIMITY SENSOR, OPERATIONALLY TESTED WITH NO DEFECTS, AND THE AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE.
