During a preflight of my year-old Sport 2 135 this past weekend, I noticed the bolt that goes through the hinge at the top of both uprights was sunk in the nylock nut. In other words, instead of 2 threads of the bolt screw showing above the nylock nut, the bolt was 2 threads *below* the nylock nut surface.
Looked at all the other WW wings in the LZ (T2C, Sport 2s) - all of their bolts showed 2 threads above the nylock nut.
Because the hinge keeps the bolt from turning, I'm worried the bolt might be stripped which caused it to sink in the nylock.
Took 1 upright off and rotated the hinge on the nylock nut side 360° while holding the bolt head steady with nose pliers so 1/2 of a bolt thread now shows above the nylock nut. Couldn't turn the hinge for another 360° because the hinge edge bumps up against the keel.
Is this sufficient for safe flying? There is a fly-in I'm attending at a site with notoriously rough air this weekend. Wondering if I need to disassemble the frame to inspect the bolt....
Has anyone heard of this happening to someone else + what caused it + how s/he solved it?
Thank you for your time.
