## Discrepancy

(CAN) AFTER SHUTDOWN SMOKE WAS NOTICED COMING FROM THE INTAKE AND THE EXHAUST. TROUBLESHOOTING REVEALED A FAULTY CHECK VALVE BETWEEN THE FUEL BOOSTER PUMP AND THE ECOLOGY PUMP LETTING FUEL INTO THE BURNER CAN. THE CHECK VALVE WAS REPLACED, THE ENGINE INSPECTED AND GROUND RUN SERVICEABLE.
