## Discrepancy

(CAN) DURING INSTALLATION OF BOLTS IN THE BRAKE ASSEMBLY, THE BOLT SHEARED OFF. THE TORQUING PROCEDURE WAS RECHECKED (275-285 IN/LBS.) AND A SUBSEQUENT BOLT SHEARED OFF. THE VENDOR M&M AEROSPACE HARDWARD INC., WAS NOTIFIED AND WE WERE ADVISED THAT THE MANUFACTURER - MERCURY - WAS OUT OF BUSINESS. ALL MERCURY HARDWARE REMOVED FROM M&M STOCK. BOLT SENT FOR LAB ANALYSIS.
