## Discrepancy

CREW RETURNED TO FIELD DUE TO A RUMBLING NOISE FROM THE NOSE LANDING GEAR AREA AFTER GEAR RETRACTION.  THE AIRCRAFT WAS FERRIED TO SDF FOR FURTHER TROUBLESHOOTING.  MAINTENANCE REPLACED THE NOSE LANDING GEAR DOOR SOLENOID, ALL THREE HYDRAULIC MANIFOLD FILTERS, BOTH NOSE LANDING GEAR TIRES, AND ADJUSTED THE NOSE LANDING GEAR SPIN BRAKE.
