It would be interesting to know if there is a commonality between all
of these discrepancies. Was the bonding paste always too thin or did
they mix it according to the clearances of each wing? If the mixture
really was too thin causing a void of 14-15 inches long then there are
probably many other voids which can't be seen on video. There needs
to be an ultrasonic inspection procedure developed which can map the
bonding interface.


I have no first hand knowledge. Talked to the owner of a well known,
respected composite repair shop who said that cotton threads are added to
the epoxy to thicken it and keep it from running. And that apparently they
had failed to add enough cotton fiber and this resulted in epoxy running
out, creating the voids.
