GVII - Noisy Wing Links

There are a series of large and small wing links that do the job of attaching the wings to the fuselage. They are shaped like dog bones and have hollow pins in bushings held in place with bolts at each end. The tolerances are very small but with some aircraft there can be some play that is noticed during turbulence as a slight popping noise. The fix is to shore the airplane to remove the load from the affected wing link and replace the bushing. The shoring process takes a day the remove and replace operation just a few minutes.

So how do you know you have this problem? I was told someone seated over the wings might notice a slight popping noise underneath during "heavy turbulence." We noticed it in turbulence that I would call no worse than moderate. So we replaced two wing links.
