We have sold approximately 300 sets of these brackets and hold a PMA for their sales. We sell only exchange, and inspect the return brackets, We find the only way to find cracks is to bead blast the bracket, as anything else will not remove the urethane paint covering the cracks and pitting. Paint stripper and magnesium do not work well together. From day one, the return brackets are shown to be 100% corroded, 70% are badly corroded, and 30% are cracked somewhere. Many planes are still being operated with the old Magnesium brackets, using first one excuse , then another to not change them, the casting number is one confusing factor, but the inability to do a real inspection is the most common reason for not changing them. They look very nice, till one bead blast them, then the corrosion comes up out of the cracks and pits, showing their real condition. We also find Cessna 310 brackets substituted, but they are not the same, they do not have the offset in the bearing boss.
