## Discrepancy

(CAN) WHEN DOING SOME TROUBLESHOOTING ON AN ENG SNAG, THE FUEL SHUTOFF VALVE WAS FOUND TO NOT BE FUNCTIONING.  IT WAS REMOVED FROM THE ACFT AND TESTED ON THE BENCH WERE IT FAILED ON A SERIES OF TESTS.  VALVE, WHEN TESTED, WOULD STICK OPEN AND CLOSED ON VARIOUS TESTS.  THE FSO VALVE WAS REPLACED WITH A NEW ONE.
