## Discrepancy

PIT - FL 696 - AFTER TAKEOFF, CREW COULD NOT RAISE GEAR HANDLE.  AFTER RAISING THE GEAR WITH THE LOCK OVERRIDED AND RETRACTING THE FLAPS, THE TAKEOFF WARNING HORN SOUNDED CONTINOUSLY.  FLIGHT RETURNED TO FIELD AT  PIT AND LANDED WITHOUT FURTHER INCIDENT.  NO EMERGENCY WAS DECLARED.  MAINTENANCE REMOVED AND REPLACED THE M991 GROUND SENSE LOGIC CARD PER MM 32-09-20.  OPERATIONAL CHECK GOOD.  (M)
