## Discrepancy

THE PILOT DEPARTED THE BASE EN ROUTE FOR A PATIENT.  OUTSIDE AIR TEMP WAS 3 3DEG F.  THE HEATING & DEMISTING SYS WAS SWITCHED ON.  AS THE AIRCRAFT STARTED TO HEAT UP WE NOTICED A STRONG ODOR, IT WAS NOT THE NORMAL SMELL OF THE HEATING SYS WARMING UP BUT A STRONGER SMELL.  THE PILOT TURNED THE HEATING & DEMISTING SYS OFF, OPENED THE PILOTS WINDOW & ABORTED THE FLIGHT & RETURNED TO BASE.  THEY LANDED WITHOUT INCIDENT & THE AIRCRAFT WAS SHUT DOWN & THE MECHANIC NOTIFIED.  THE MECHANIC INSPECTED THE SYS & FOUND NO DEFECTS.  A GND RUN & FLIGHT CHECK WERE COMPLETED WITH NO NOTICEABLE SMELLS OR DEFECTS NOTED.  THE AIRCRAFT WAS THEN RETURNED TO SERVICE.
