What was found

DURING A SCHEDULED INSPECTION, THE LT OTBD NOSE STEERING PULLEY BRACKET JUST FORWARD OF THE FORWARD PRESSURE BULKHEAD WAS FOUND TO BE CRACKED. THE CRACK WAS EMANATING FROM THE LOWER FORWARD CORNER RADIUS AND THE PULLEY LOAD HAD DEFORMED THE BRACKET A QUARTER INCH. THE PART IS ROBUST IN BUILD BUT IS ONLY SUPPORTED ON 2 ENDS. THESE PULLEY BRACKETS ARE A COMMON POINT OF DEFECT.
