## Discrepancy

CREW REPORTED THAT AFTER TAKEOFF, THE LANDING GEAR WOULD NOT RETRACT.  THE CREW RETURNED TO FIELD AND LANDED WITHOUT INCIDENT.  THE AIRCRAFT WAS FERRIED TO KSDF WITH THE LANDING GEAR DOWN AND LOCKED.  SDF MAINTENANCE REPLACED THE LANDING GEAR OVERRIDE SWITCH.  OPERATIONAL CHECKS AND GEAR SWING CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
