## Discrepancy

DURING CLIMBOUT THROUGH 10,000 FT THE CABIN DOOR WARNING LIGHT CAME ON.  CREW FOLLOWED EMERGENCY CHECKLIST PROCEDURES & RETURNED TO THE STATION.  THE MICROSWITCH ON LATCH CAM INSIDE THE DOOR WAS FOUND SLIGHTLY OUT OF ADJUSTMENT DUE TO WEAR & WAS ADJUSTED.  THE DOOR WARNING SYSTEM OPS CK GOOD AFTER ADJUSTMENT.  THE WEAR ONLY MANIFESTED ITSELF AS THE AIRCRAFT WAS PRESSURIZED.
