## Discrepancy

THE CREW REPORTED THAT WITH BLEED AIR SELECTED, THERE WAS SMOKE AND NOISE COMING FROM THE RIGHT HAND PACK.  THE AIRCRAFT WAS THEN FERRIED TO CAK.  MAINTENANCE INSPECTED AND FOUND THE AIR COOL MACHINE BLADES WERE DAMAGED.  MAINTENANCE THEN REPLACED THE RIGHT HAND PACK IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 21-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
