## Discrepancy

AFTER LANDING, CREW SMELLED AN ELECTRICAL BURNING ODOR IN THE CABIN, WHICH WAS ELIMINATED IMMEDIATELY UPON OPENING THE CABIN DOORS. NORMAL SHUTDOWN WAS COMPLETED. WHEN BASE MECHANIC ARRIVED, WE SEARCHED FOR A SOURCE OF THE SMELL AND WHEN NONE WAS FOUND, WE RAN-UP THE AIRCRAFT WITH ALL ELECTRICAL COMPONENTS ON AND COULD NOT REPRODUCE THE ODOR.  AIRCRAFT WAS RETURNED TO SERVICE. I SUSPECT THAT THE ODOR DID NOT ORIGINATE FROM THE AIRCRAFT, BUT RATHER FROM THE HOSPITAL'S PLANT OPS, WHICH WAS DIRECTLY UPWIND OF THE 5TH FLOOR HELIPAD. POSSIBLY FROM WELDING.
