## Discrepancy

AFTER TURNING PACKS ON, RIGHT PACK TRIPPED OFF.  COMPRESSOR OUTLET TEMPERATURE IN RED BAND,  LEFT PACK WAS APPROACHING YELLOW BAND.  NOTICED HIGH DUCT TEMPERATURE, DUCT OVERHEAT LT LIGHT AND PACK TRIP OFF.  SMOKE FILLED BOTH COCKPIT AND CABIN.  *S/D*  AFTER MAINTENANCE THAWED BOTH PACKS THE OPERATIONAL CHECK WAS OK.
