## Discrepancy

AS THE AIRCRAFT APPROACHED 20-30 KNOTS THE CREW RECEIVED A DOOR SWITCH FAIL CAS MESSAGE.  THE CREW ABORTED TAKEOFF AND REFERENCED THE QUICK REFERENCE HANDBOOK.  THE CAS MESSAGE CLEARED ITSELF.  THE CREW CONTACTED MAINTENANCE CONTROL AND WERE ADVISED TO MAKE ANOTHER TAKEOFF ATTEMPT.  FLIGHT 4021 THEN DEPARTED WITHOUT ANY FURTHER INCIDENTS.
