## Discrepancy

(CAN) DURING A SCHEDULED INSPECTION, THIS BOLT (IPC PAGE 2-4 ,FIGURE 2-5, ITEM NR 15) WAS FOUND LOOSE. THIS IS THE THIRD AIRCRAFT IN THE FLEET ON WHICH THIS BOLT WAS FOUND LOOSE, ALL AIRCRAFT WERE UNDER 1000HRS TSN.  IT IS VERY NOTICEABLE WHEN WIGGLING THE TAIL BOOM SIDE TO SIDE.  THE BOLT WAS TIGHTENED WITH NO FURTHER ISSUES.
