What was found
BRACKETS ARE MADE OF MAGNESIUM, CORRODING AND CRACKING. APPROXIMATELY 80 PERCENT OF THE BRACKETS INSPECTED BY BEAD BLASTING ARE UN-AIRWORTHY. PROBLEM OF CORROSION BETWEEN BEARING AND BOSS WHICH EXPANDS AND CRACKS THE BOSS. SEPARATION OF AILERON FROM REAR WING SPAR WHILE STILL ATTACHED TO STEEL ACTUATOR ROD WOULD MOST LIKELY RENDER THE AIRCRAFT UNCONTROLLABLE. WE HAVE BEEN URGING EVERYONE TO REMOVE THESE BRACKETS FROM THE AIRCRAFT AND BEAD BLAST THE BODY WHILE PROTECTING BEARING. CHEMICALLY STRIPPING DOES NOT REMOVE CORROSION BY PRODUCTS.
