## Discrepancy

CREW REPORTED THAT AFTER TAKEOFF THEY RECEIVED A LANDING GEAR AIR & GND FAIL MESSAGE & THAT THE LG WOULD NOT RETRACT.  THE CREW RETURNED TO FIELD & LANDED WITHOUT INCIDENT.  ONCE ON THE GND SEVERAL FAIL MESSAGES APPEARED.  MX FOUND THAT THE RT INBD TIRE HAD SEPARATED.  PERFORMED A TIRE SEPARATION INSPECTION.  MX REPLACED THE NR 3 MLG TIRE.  MX ALSO REPLACED THE W510, W509, W514 & W512 LG HARNESSES.  LG SWINGS & OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
