## Discrepancy

WHEN ENG ANTI-ICE WAS TURNED ON, THE BLEEDS TRIPPED OFF & CABIN PRESS STARTED TO CLIMB.  EMER WAS DECLARED &  A DESCENT WAS STARTED.  RESET PACK TRIP, PRESSURIZATION RETURNED TO NORMAL.  FLIGHT DECLARED AN EMER, DIVERTED & LANDED WITHOUT FURTHER INCIDENT.  ACFT WAS REMOVED FROM SERVICE.  INSPECTED & RAN BOTH ENGS AT IDLE WITH ALL BLEEDS ON.  GND CHECKED ANTI-ICE, BLEED & PRESSURIZATION SYSTEMS.  NO PROBLEMS FOUND.
