Thanks Dan and Larry .... I think it is the bolt holes, or maybe the bolts ... I'll check and see. The movement is definitely between the two halves of the wing at the WAFs and was checked with the bolts inserted but not tightened up at all. ....... Just when I thought we were almost ready to fly! Still, better to find the problem now and not at 2000 ft over the bay ....
Is there a spec for the maximum diameter permitted for the bolts? I have heard that overlarge bolts will reduce the load tolerance of the WAF .... Has anyone bushed the fittings and maybe used a taper pin to eliminate wear over time?
