## Discrepancy

AFTER TAKEOFF, THE CREW ATTEMPTED TO RETRACT THE LANDING GEAR AND RECEIVED A LANDING GEAR AIR/GROUND FAIL MESSAGE ON EICAS, AND WERE UNABLE TO MOVE THE HANDLE TO RETRACT THE LANDING GEAR.  THE AIRCRAFT RETURNED TO CLE AND LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED ALL THE LANDING GEAR PROX SWITCHES WITH NO DEFECTS NOTED AND THE NOSE LANDING GEAR STRUT SERVICING WAS VERIFIED AS CORRECT.  THE LANDING GEAR ELECTRONIC UNIT WAS REPLACED AND THE GEAR SWINGS WERE PERFORMED WITH NO FURTHER DIFFICULTIES.
