## Discrepancy

ON FLIGHT 2707 THE CREW REPORTED THAT ON TAKEOFF DURING THE CLIMB RECEIVED A LANDING GEAR AIR/GROUND FAIL MESSAGE.  THE CAPTAIN DECLARED AN EMERGENCY AND ELECTED TO RETURN TO DFW.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  THE AIRCRAFT WAS REMOVED FROM SERVICE.  REMOVED AND REPLACED THE LANDING GEAR ELECTRONIC UNIT.  THE OPERATIONAL CHECK WAS GOOD.  THE AIRCRAFT WAS RETURNED TO SERVICE.
