From memory the Winton one the wing spar failure resulted from an
uncontained engine fire that in turn was the result of an incorrect
assembly of an auxillary drive on the engine. Nothing to do with the wing
itself, except it was not fireproof.
Both were maintenance problems, not airframe defects except in the sense
that it was possible (easy?) to do the wrong thing.
