## Discrepancy

THE EMERGENCY FUEL SHUT OFF VALVE HAD FAILED THE INTERNAL LEAK RATE OF 1 LITER PER HOUR. A NEW VALVE WAS ORDERED UNDER WO# 267A-2019-I-0049-0093 AND IT TOO FAILED THE INTERNAL LEAK RATE CHECK. ANOTHER NEW VALVE WAS ORDERED UNDER THE SAME WO# AND IT FAILED THE INTERNAL LEAK RATE CHECK AS WELL. THE THIRD NEW VALVE ORDERED PASSED THE LEAK RATE CHECK. THIS WAS 2 NEW VALVES IN SUCCESSION TO FAIL.
