## Discrepancy

THE CREW REPORTED THAT THERE WAS A LOUD AIR NOISE FROM THE FRONT OF THE ACFT AND PRESUMED THAT THE LANDING GEAR DOORS REMAINED OPEN IN FLIGHT.  THE CREW RETURNED TO FIELD AND LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE NLG DOOR SOLENOID VALVE.  OPS CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
