## Discrepancy

CREW REPORTED, THAT THE RIGHT AIR CYCLE MACHINE ONLY BLOWS HEAT, SMELLED AN  ELECTRICAL SMELL WITH BLEEDS ON AND PASSENGERS REPORTED A GRINDING SOUND IN THE BACK OF THE AIRCRAFT.  MAINTENANCE FOUND THE RIGHT AIR CYCLE MACHINE SEIZED.  REPLACED THE RIGHT ACM AND RETURNED THE AIRCRAFT TO SERVICE WITH NO FURTHER PROBLEMS.
