I had a break in an aluminum fan but it wasn't a blade. A chunk of metal broke out of the key way groove, making it about twice the size it should have been. Sounded like a bad timing gear or bearing. Probably, my fault for not making sure the bolt was kept tight but could have been a bad casting. After having a cracked blade on my '31 Chrysler about the same time, I went to a plastic fan on the "A" and have felt comfortable and safe with it since. Too many stories about broken blades and the damage they can cause.
