Eagle crankshaft

That is a strange break. The break seems to go straight across the side of the journal. It's almost as if something kept the two sides of the mold apart when the casting took place. I agree with all that quality control should have picked it up. If I had an Eagle crank ready for install now, I'd have it magnafluxed first.

Aircraft fasteners from China were a big problem about twenty years ago. The issue was too much porosity and out right misrepresentation of fasteners as being Grade 8 quality. The grain in the pictures of the casting seems to be too coarse for this application. Is it just me? Any metalurgists on this site?
