I'm not exactly how to word this, RV7 with 95 hours currently doing the first condition inspection. Not sure how I didn't notice before, but while running wires through the outboard seat ribs up top I noticed that the belly skin was arched up and would "pop can." Underneath the airplane between the front spar and rear spar, it appears the flange of the outboard seat rib rivet flange has been tweaked upwards. Now that I'm looking for it it is very noticeable, both left and right sides are the same.
Right side, you can see the curvature of the skin reference the ruler on the outboard seat rib bay.
Left side...
My non-engineering simplistic thoughts may attribute it to the weight of the wings while on the ground?
I don't have negative G systems and the airframe has only been to -1 G for testing, ideas?
