## Discrepancy

AFTER TAXIING FROM THE GATE, THE FLIGHT ATTENDANT NOTIFIED THE CAPTAIN THAT THERE WAS SMOKE ENTERING THE CABIN.  THE CAPTAIN SHUT DOWN THE PACKS AND BLEEDS AND CONFIRMED THERE WAS SMOKE IN THE CABIN.  THE CAPTAIN RETURNED TO THE GATE AND DEPLANED THE PASSENGERS.  MAINTENANCE INSPECTED AND REPLACED THE PACK VALVE IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 21-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
