## Discrepancy

PILOT REPORTED BURNING RUBBER SMELL IN COCKPIT UPON ENGINE SHUTDOWN BACK AT BASE. HE MADE A LOG BOOK ENTRY NOTATING THE DISCREPANCY AND CALLED ME IN TO INSPECT THE AIRCRAFT. I INSPECTED THE AIRCRAFT VENTILATION, HEATING AND AC SYSTEMS. ALL WERE FOUND TO BE IN AN AIRWORTHY CONDITION I THEN PERFORMED A GENERAL VISUAL INSPECTION OF ALL THE MAJOR COMPONENTS ON THE AIRCRAFT. THE PILOT AND I THEN PERFORMED A GROUND RUN OPERATIONAL CHECK OF ALL THE AIRCRAFT SYSTEMS. OPS CHECK NOTED GOOD. NO PROBLEMS FOUND.
