## Discrepancy

IAH - DURING TEST FLIGHT THE CREW REPORTED A LANDING GEAR AIR/GROUND FAIL MASSAGE FOR APPROXIMATELY 5 SECONDS AFTER SELECTING GEAR UP.  AFTER SUBSEQUENT GEAR CYCLES, THE MESSAGE REMAINED ON EICAS.  THE AIRCRAFT RETURNED TO IAH WHERE MAINTENANCE REMOVED AND REPLACED RELAYS K0352, K0353, AND K0453 WITH NO HELP, AND ADJUSTED THE RIGHT MLG WOW PROXIMITY SWITCH.  OPERATIONALLY TESTED WITH NO DEFECTS AND THE AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE.
