## Discrepancy

(CAN) A REPLACEMENT ATTACH BOLT FOR THE FLIGHT CONTROL RODS WAS PURCHASED & RECEIVED BY NWA STORES. UPON PRE-INSTALLATION INSPECTION OF THE BOLT, (P/N NAS464P5-25) AN OPEN DEFECT WAS NOTED ON THE TOP CENTER OF THE HEAD AS WELL AS A DARK LINE IN THE SHANK JUST BELOW THE HEAD ON APPROXIMATELY 1/2 THE CIRCUMFERENCE OF THE SHANK. BOTH DEFECTS WERE SCANNED USING EDDY CURRENT EQUIPMENT & RETURNED A POSITIVE FLAW INDICATION. BOLT WAS SCRAPED FROM INVENTORY AND PLACED IN QUARANTINE. (TC# 20190529010)
