One here in NZ had a void of 14-15 inchs long,the engineers here think
the problem has been from making the glue mixture to thin and it has just
flowed out of the rear side as there is a ridged edge on the front side to
make all the mix go towards the rear.
One comment made was they thought that the factory had attempted to
push some mix into that void by hand by reaching through the access point
but had only been partially successful

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.
