## Discrepancy

IN ROUTE WITH PATIENT TO RECEIVING HOSPITAL, CRUISE FLIGHT. CREW NOTICED A STRONG ODOR OF WHAT SMELLED LIKE BURNING ELECTRONICS. I NOTICED THE AIR CONDITION COMPRESSOR WAS STILL INDICATING ON AND GOOD AIRFLOW FROM THE VENT. I PERFORMED A TURN TO THE LEFT AND RIGHT TO SEE IF WE WERE TRAILING ANY SMOKE AND NO SMOKE WAS VISIBLE. NO CAUTION LIGHTS ON. AS THE SMELL INTENSIFIED, I DECIDED TO DIVERT TO AN AIRFIELD APPROX 2 MILES AWAY AND NOTIFIED AIRCOM. AS WE APPROACHED THE AIRPORT, I OBSERVED SMOKE RISING BETWEEN ME AND THE INSTRUMENT PANEL. I MADE A CALL ON CTAF OF MY INTENTIONS TO LAND AND THEN TURNED OFF ALL AVIONICS AND OPENED MY WINDOW. ON SHORT FINAL THE SMOKE AND SMELL SEEMED TO DISAPPATE. MADE A NORMAL APPROACH AND LANDING TO THE RAMP. NORMAL SHUT DOWN AS WELL. MADE ALL THE CALLS AND WROTE UP THE DISCREPANCY. MAINTENANCE DETERMINED IT WAS A SEIZED AC COMPRESSOR WHICH BURNED AND BROKE THE DRIVE BELT. AIRCRAFT PLACED ON MEL AND MAINTENANCE FLIGHT COMPLETED WITH NO ISSUES. RTB.
