## Discrepancy

(CAN) DURING REPLACEMENT OF STARFLEX, DISCOVERY OF ONE OF TWELVE BOLT FOUND BROKEN. PRESENCE OF RUST ON THE BROKEN SECTION, SHOWS THAT THE DEFECT OCCURRED A LONG PERIOD BEFORE DISCOVERY.BECAUSE OFTHE DESIGN OF THE HEAD, THERE WAS NO POSSIBLE WAY TO LOSE ANY PART. NOTE THAT RETIREMENT OF STARFLEX AND BROKEN SCREW IS 2200 HOURS.ATTACHMENT SCREW P/N 350A37-1245-20, S/N 28998
