What was found
BOTH BRACKETS CRACKED ALL THE WAY ACROSS BEARING BOSS, SEVERLY CORRODED AND MOUNTING LEG OF ONE BRACKET BROKEN OFF. THE PROBLEM WITH THESE BRACKETS IS THE HIGHLY REACTIVE MAGNESIUM WHICH THEY ARE MADE OF. THIS IS A HIGHLY CRITICAL COMPONENT AND SHOULD BE INSPECTED CLOSELY OR REPLACED.
