## Discrepancy

PRIOR TO TAKE OFF, TURNED ON THE ACFT`S AIR CONDITIONER.  DURING CLIMB OUT WE SMELLED AN ELEC BURNING SMELL & ASSOCIATED GREY SMOKE COMING FROM THE NOSE OF THE ACFT.  TURNED OFF THE THE AIR CONDITIONER, PERFORMED THE EMERGENCY PROCEDURE FOR SMOKE IN THE COCKPIT & LANDED BACK ON THE HELIPAD & COMPLETED THE SHUTDOWN WITHOUT ANY FURTHER INCIDENT.  THE AIR CONDITIONER COMPRESSOR BELT HAD HEATED & BROKE.
