## Discrepancy

FLIGHT, KHYA-KFLL, ON ARRIVAL INTO KFLL AT FL190 WE RECEIVED A AMBER CABIN DOOR OPEN CAS MESSAGE.  NO AUDIBLE SIGN OF A DOOR OPEN OR CRACKED OPEN, NO PRESSURIZATION CHANGE.  WE COMPLIED WITH THE CABIN DOOR OPEN AMBER CAS QRH 21C.  THE CAS MESSAGE STAYED ON FROM FL190 UNTIL SOMETIME BETWEEN SHORT FINAL AND TAXI TO FBO AND WE NOTICED IT HAD EXTINGUISHES ON ITS OWN. FLIGHT TIME BETWEEN THE MESSAGE AND EXTINGUISHING WAS AROUND 35 MINUTES.  ADJUSTED PROX SWITCH. OPS CHECK GOOD. IAW CE700 AMM 52-70-00
