Yikes!  Can you say more about what we are looking at - which plane - what prompted you to get an xray and so forth?

this is the propeller hub on a Mooney M20-C, we were doing the Eddy current inspection and got a reading that there was a crack. We removed the shotpeening dipped it in zyglo and the crack clearly showed up in the dark area.....
