What was found
TAKING OFF FROM BASE TO PR EVENT, THE MED CREW BEGAN TO SMELL ELECTRICAL TYPE BURNING SMELL WITH THE CABIN. THE SMELL WAS STRONG FROM THE PILOT SEAT SO I COULD ONLY ASSUME THAT IT WAS POSSIBLY SOMETHING FROM THE COCKPIT AREA. STARTED TO ISOLATE THE PROBLEM BY VERIFYING AIRCRAFT HEAT WAS OFF. THEN NOTICED THAT THE PILOT STATIONED A/C VENTS WERE NOT BLOWING AIR, TURNED A/C OFF. WITHIN 30 SECONDS AFTER TURNING A/C OFF, SMELL APPEARED TO DISSIPATE AND ONE ON THE GROUND (2 MINUTES LATER) CREW COULD NO LONGER SMELL THE ELECTRICAL BURNING. COULD ONLY ASSUME THAT WE WERE HAVING A/C ISSUES AND DID NOT CONTINUE TO ISOLATE THE PROBLEM ANY FURTHER WHILE IN FLIGHT. DURING OUR 3 MINUTE FLIGHT THERE WAS NEVER ANY EVIDENCE OF SMOKE IN THE CABIN. WE ABORTED THE FLIGHT AND MECHANIC WAS ALREADY ON SITE AND IMMEDIATELY BEGAN TO TROUBLESHOOT.
