## Discrepancy

CREW REPORTED THAT THEY RECEIVED A LANDING GEAR AIR/GROUND FAIL MESSAGE WITH AN ASSOCIATED ENGINE 1 AND 2 REVERSE DISAGREE MESSAGE DURING LANDING GEAR RETRACTION.  THE CREW RETURNED TO FIELD AND LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE SERVICED THE NOSE LANDING GEAR STRUT.  OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
