## Discrepancy

ON INITIAL CLIMB AFTER DEPARTING RNWY 35L FOR A FLIGHT AT APPROX 2,000 MSL, THE RED CABIN DOOR MASTER WARNING LIGHT ILLUMINATED.  COPILOT WAS DIRECTED BY THE PIC & PF TO REQUEST A RETURN TO THE AIRPORT.  ATC ISSUED INSTRUCTIONS FOR SEQUENCE & AN UNEVENTFUL LANDING WAS MADE ON RNWY 35L.  AFTER EXITING THE RNWY, THE MS CHECKED THAT ALL LOCKED INDICATORS ON THE DOOR WERE IN FACT ENGAGED.  MS OPENED & CLOSED THE DOOR & RECHECKED ALL LOCKED INDICATORS WERE PROPERLY POSITIONED BUT THE LIGHT STAYED ON.  CREW ELECTED TO RETURN TO THE LINE FOR MX ACTION.  ADJUSTED CABIN DOOR WARNING SWITCH.
