## Discrepancy

MED CREW REPORTED SMELLING FUEL IN CABIN DURING THE SECOND LEG OF A PATIENT TRANSPORT FLIGHT. THE AIRCRAFT WAS LANDED, AND MECHANIC WAS CALLED TO INSPECT THE AIRCRAFT. THE BAGGAGE COMPARTMENT MEDICAL SERVICES PANEL WAS REMOVED TO EXPOSE A FUEL VALVE THAT WAS THOUGHT TO BE THE SOURCE OF THE SMELL; HOWEVER NO LEAKS OR FUMES WERE DETECTED. THE MECHANIC INSPECTED THE AIRCRAFT AND RELEASED IT BACK TO SERVICE FOLLOWING A THOROUGH INSPECTION WITHOUT A SOURCE FOR THE SMELL IDENTIFIED.
