## Discrepancy

DURING AN INSPECTION AFTER LANDING ON THE HIGH WAY IT WAS FOUND THAT A ROLL PIN IF THE FUEL SELECTOR HAD SHEARED. IT IS STILL UNCLEAR AT WHAT POINT THE ROLL PIN FAILED AS THERE WERE SEVERAL FLIGHT PRIOR THAT DAY WITH NO ISSUES NOTED. THE ROLL PIN WAS REPLACED AND A TEST FIGHT WAS PERFORMED WITH NO ISSUES.
