## Discrepancy

DURING A NORMAL LANDING, THE PILOT HEARD A BANG AND INVESTIGATED AND FOUND THE TIE BOLT BROKEN.  THERE WAS NO FURTHER DAMAGE TO THE AIRCRAFT, PILOT OR PASSENGERS.  A NEW BOLT REPLACED THE BROKEN BOLT AND NO FURTHER ISSUES WERE REPORTED.  THE BROKEN BOLT WAS RETURNED TO FAC (FOUND AIRCRAFT COMPANY) AND THE INITIAL INVESTIGATION APPEARS TO BE HYDROGEN EMBRITTLEMENT.  THIS INFORMATION HAS BEEN PASSED ON TO THE MATERIAL SUPPLIER AND HEAT TREATED.  THIS SHALL BE UPDATED AS FURTHER INFORMATION IS RECEIVED FROM THE VENDORS.
