## Discrepancy

FLT NR 1580 - GSO - THE LANDING GEAR WOULD NOT RETRACT AFTER TAKEOFF FROM GSO.  THE AIRCRAFT WAS RETURNED TO GSO WHERE IT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE AIR/GROUND PROXIMITY SENSOR AT FAULT.  THE SENSOR WAS REPLACED AND GEAR RETRACTION WAS NORMAL.  OTHER GROUND SENSE FUNCTIONS ALSO CHECKED GOOD.  (M)
