The A&P agrees but we spent a good couple of hours trying to bend the sheet metal to fit it right and never got there. The way the crack sits, I can't put much force on the section to bend the sheet metal patch to the contour of the sowling. The crack sits right at the most complex curve on there. I am thinking if he welds it, then I may be able to bend a piece of sheet around it and rivet that in. I don't know. The entire thing is a big pain. I did find a place that will sell me an entire upper cowling for $430. Anyone need the upper cowling sans upper nose bowl?
