## Discrepancy

PDIS  618     30-20  7669     16MAR19  MCI  OPEN  U  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.            REMOVED AND REPLACED THE #2 ENGINE ANTI-ICE DUCT                                  BURST DETECTION UNIT REFERENCE BOEING MD-11 AMM                                   30-22-10-4.
