## Discrepancy

(CAN) DURING INSPECTION ON SPAR, WHEN BOLT WAS BEING INSTALLED IT WAS FOUND THAT AFTER FINAL TORQUE THE BOLT COULD STILL BETURNED QUITE EASILY. BOLT WAS REMOVED AND MAINTENANCE FOUND THAT THREADS WERE RAGGED AND CAUSING THE NUT TO BIND ON THE BOLT. THIS IS THE SECOND CASE WE HAVE SEEN IN THE LAST 6 MONTHS.
