## Discrepancy

ON CLIMBOUT FROM HOSPITAL HELIPAD, IA THE FLIGHT CREW SMELLED SMOKE IN THE CABIN.  PILOT LANDED BACK AT HELIPAD WITHOUT DELAY.

AIR CONDITIONER INOP WAS PLACED ON MEL DEFERRAL UNTIL THE FOLLOWING MORNING TO FACILITATE MX.  AIR CONDITIONER COMPRESSOR DRIVE BELT WAS REPLACED ON 8/10/2010.
