## Discrepancy

WHILE THE ENGINEER WAS CARRYING OUT A DAILY INSP, FOUND HALF A BOLT WITH NUT ATTACHED ON ENG DECK.  FURTHER INVESTIGATION REVEALED THAT BOLT (ONE OF TWO) WAS PART OF THE ATTACHMENT OF THE PILLOW BLOCK ASSY TO THE ENG BIPOD MOUNT ASSY.  PART OF THE BOLT APPEARED TO HAVE BEEN CRACKED FOR SOME TIME. THE OTHER HALF OF THE BOLT HEAD WAS NOT FOUND. THE SECOND BOLT HAD SIGNIFICANT WEAR. BOTH BOLTS WERE REPLACED ON THE ENG BIPOD/PILLOW BLOCK ATTACHMENT.
