Nose rib flange failure
For some reason we ended up with a few nose ribs that have a little indentation on the front lightening hole. If you look very close at the picture you can see a small indention on the right side of the lightening hole. Since it was a smooth indention I tried pressing it but of course it cracked right in the indentation. We'll have to remake six nose ribs. No biggie. Below are the pictures showing what happens. So the lesson learned is that the holes need to be perfectly round and smooth or you'll get cracks.
