PDIS 618 30-20 7669 16MAR19 MCI OPEN U LOGPAGES:2999060 PREVIOUS WRITEUP FOR "ENG 2 A-ICE DISAG", SHOULD HAVE BEEN "ENG 2 A-ICE OFF". THE DISAG LIGHT ON THE ENG 2 ANTI-ICE SWITCH ILLUMINATED AS A RESULT OF THE "OFF" ACTION DUE TO THE AIRCRAFT DETECTING A LEAK IN THE ENGINE 2 ANTI-ICE DUCT. SINCE THE MEL ACTION WIRED THE ANTI-ICE VALVE OPEN, THERE WAS NO WAY FOR THE AIRCRAFT TO PROTECT ITSELF. AFTER DISCUSSING WITH MOCC & GOCC, THE DECISION WAS MADE TO SHUTDOWN #2 ENGINE (WINDMILL FOR 25 MINUTES, AFTER 10 MINUTES AT IDLE) AND DIVERT TO KMCI.
