Just wondering if anyone else has had this issue.

I noticed cracks (3 of them) in the spinner backing plate of my counterweighted MT prop for my Legacy.  I have been keeping an eye on it because Ralph Love has had two plates crack on him.  I have had the prop about a year, it was dynamically balanced. Of interest both Ralph and I have Performance engines that have been inspected and altered ie bad parts out good parts in.
