Hello. We have just started repairing what I believe to be a common issue with the outboard wing panel of a PT-19. The trailing edge just inboard of the aileron has suffered extensive rot of the trailing edge stringer, rib tips, and plywood covering. We have decided to remove the plywood covering up to the aft spar both on the upper and lower surface of the wing. The exposed ribs are in mostly good shape with the exception being the aft sections. We have decided to remove the rotten sections of the ribs and rebuild and reinforce them appropriately. I was writing to see if anyone knows of a place we could get copies of the original full size rib diagrams. There is a small chance we may have to rebuild an entire rib. Also, the aft stringer has completely rotted away so we really have nothing to go on as far as design goes. The plans would help but if anyone happens to have a wing that is open and could send a pic of the attachment of the stringer it would be greatly appreciated. Thank you for your time in advance..
