## Discrepancy

SHORTLY AFTER TAKEOFF THE MED CREW NOTICED A STRONG FUEL SMELL IN THE CABIN AND COULD SEE LIQUID ON THE BACK CLAMSHELL WINDOW.  THE PILOT IMMEDIATELY RETURNED TO THE DEPARTURE AIRPORT AND AWAITED THE MECHANIC TO ARRIVE.  THE MECHANIC TROUBLESHOT THE FUEL LEAK AND DETERMINED THAT THE FUEL SHUTOFF VALVE HAD FAILED.  THE ACFT WAS TAKEN OUT OF SERVICE TO AWAIT THE PART TO BE RECEIVED THE NEXT DAY.  THE PART WAS RECEIVED AND REPLACED.  THE OPS CHECK WAS GOOD AND THE ACFT WAS RETURNED TO SERVICE.
