## Discrepancy

DIVERTED DUE TO A LT BLEED DUCT WARNING MESSAGE.  CREW FOLLOWED QRH, WHICH REQUIRED THEM TO LEAVE ICING CONDITIONS AND LANDED AT THE NEAREST SUITABLE AIRPORT.   DECLARED AN EMERGENCY.   MX PRESSURIZED THE AIR CONDITIONING DISTRIBUTION SYSTEM WITH ENGINE BLEED AIR, NO FAULTS POSTED AND NO ABNORMAL SYNOPTIC PAGE INDICATIONS. OPS CHECKED GOOD.
