## Discrepancy

AFTER TAKEOFF, THE FLIGHT CREW PERFORMED A LANDING GEAR UPLATCH CHECK.  THE LEFT MAIN LANDING GEAR UNSAFE LIGHT REMAINED ILLUMINATED.  LANDING GEAR WAS RECYCLED WITH A NOSE LANDING GEAR UNSAFE LIGHT ILLUMINATION UPON LANDING GEAR RETRACTION.  FLIGHT RETURNED TO MSP AND LANDED WITHOUT INCIDENT.  LANDING GEAR INDICATION WAS NORMAL UPON LANDING.  MAINTENANCE PERFORMED A LANDING GEAR UPLATCH CHECK AND REPLACED THE LANDING GEAR CONTROL UNIT.  OPERATIONAL CHECK NORMAL.
