## Discrepancy

THE PILOT SMELT WHAT APPEARED TO BE BURNING RUBBER IN THE ACFT RETURNING TO BASE FOLLOWING A PATIENT TRANSFER. THE PILOT TURNED OFF THE AIR CONDITIONING & OPENED UP THE FRESH AIR VENTS.  HE THEN DIVERTED TO & LANDED.  AT NO TIME WAS THERE EVER SMOKE IN THE COCKPIT.  THE MECHANIC WAS CALLED TO LOOK AT THE HELICOPTER.  ALL COWLINGS WERE OPENED & THE BELLY PAN WAS DROPPED FOR INSPECTION.  A 15 MINUTE GND RUN & 13 MINUTE TEST FLIGHT WAS COMPLETED.  WE WERE UNABLE TO DUPLICATE THE PROBLEM & RETURNED THE HELICOPTER TO SERVICE.
