## Discrepancy

PILOT REPORTED FUEL SMELL FROM CABIN DURING FLIGHT.  AIRCRAFT WAS LOOKED AT BY MAINTENANCE AND THE FUEL SELECTOR WAS FOUND LEAKING FUEL.  UPON FURTHER INVESTIATION, THE SNAP RING ON THE FUEL SELECTOR HANDLE SIDE OF THE UNIT WAS FOUND MISSING.  THIS ALLOWED THE INNER VALVE ASSY TO START MOVING OUT OF THE HOUSING ALLOWING FUEL TO LEAK PAST THE O-RING.  INSPECTED ALL LIKE AIRCRAFT IN THE FLEET FOR THE SAME DEFECT.  NONE FOUND.
