Tighten the WAF bolts to their rated torque and the outer spars will not
wiggle. It is the clamping pressure at the WAF joint that does the
functional holding. Shear on the bolts is a backup. And yes, we have had
this discussion somewhere in the archives before. Lost somewhere in the
discussion is the recommendation to re-torque the WAF bolts at each
Condition Inspection.

-----I have spent some time in the archives and there has been discussion
about this. When I trial fit the wings on the project I posted pics of the
other day in the Facebook site, I did not tighten the nuts onto the bolts
(just on loose ) but yesterday I checked for movement at the wing tips and
there is indeed movement. My question for all is ... before you tightened
the nuts ... was there any movement.
I did have the wings on my other project and as I recall even with the bolts
just through the hole there was no slop or movement.
It seems to me there should be none ideally and that perhaps the holes are
not as close tolerance as they should be.Not an insurmountable problem I
understand and no hurry on this project either.
As always,I look forward to hearing all thoughts.
