## Discrepancy

(CAN) DURING AN DI CONDUCTED BY A ENGINEER, A BROKEN SPRING WAS DISCOVERED UNDER THE CHINESE HAT.THE SPRING WAS REPLACED WITH NEW. THE OTHER SPRINGS WERE INSPECTED AND NO DEFECTS WERE FOUND. THE SPRING WHICH WAS BROKEN, SHOWED SIGNS OF A CRACK WHICH FINALLY COMPLETELY BROKE OVER TIME. THE TOTAL TIME OF THE SPRING CAN NOT BE DETERMINED AT THIS TIME.
