## Discrepancy

CREW REPORTED A LANDING GEAR AIR/GROUND FAIL MESSAGE ON THE EICAS AFTER TAKEOFF AND THAT THE LANDING GEAR WOULD NOT RETRACT.  MAINTENANCE INSPECTED THE LANDING GEAR SYSTEM AND REPLACED THE NLG WEIGHT ON WHEELS SWITCH AND CONNECTOR.  SUBSEQUENT OPERATIONAL CHECK OF THE SYSTEM PROVED A GOOD CORRECTIVE ACTION.
