## Discrepancy

ON A DAILY INSPECTION OF THE HELICOPTER, 2 BOLT HEADS WERE POPPED OFF THE STABILIZER BAR MOUNTING AREA AND ALL OTHER BOLTS WERE LOOSE.  RECORDS INDICATED 110 HRS AGO, ONE BOLT WAS FOUND LOOSE ON A PREVIOUS INSPECTION.  SUBMITTER RECOMMENDS THE AN 6H BOLTS AND MS2000266 WASHERS OF THE MILITARY CONFIGURATION BE CHANGED TO THE NAS1306 BOLTS AND AN960-616 WASHERS OF THE BELL HELICOPTER CONFIGURATION.  BOLT HAS MUCH HIGHER TENSILE STRENGTH AND WASHER HAS BETTER CONTACT AREA ON BOLT HEAD.
