## Discrepancy

AFTER DEPARTURE, CREW WAS UNABLE TO RETRACT THE LANDING GEAR.  LT MAIN GEAR INITIALLY RETRACTED THEN RETURNED TO A DOWN AND LOCKED POSITION.  RT AND NLG OPERATED NORMALLY.  AFTER COMPLETING THE GEAR MALFUNCTION CHECKLIST CREW RETURNED TO DEPARTURE FOR A NORMAL APPROACH AND LANDING.  UPON INSP, LT MLG UPLOCK SWITCH FOUND TO BE FAILED.  REPLACED SWITCH.
