Behind the wing
Tony this is my quote from 9-20-12 (260)
This will be the same profile as the wing rib and be hidden by the wing
From Loose Main Gear Legs (260)
A few more thoughts
The fuel tank on the right side of the aircraft adds weight and stiffness right behind the spar.
If the channel is rotating back ( back flange up 70% front flange down 30%) most of the stress would be at the front of the fuel tank.
The left side would have a larger area to flex and absorb the loads
A skin doubler from the back of the spar about 12" back and the size of the wing rib on the outside would add a strength to this section and would not be visible behind the wing.
And in my view the channel is rotating.
I will not rivet this area on my side skins until vans reports their findings,
And for the people that have damage removing the rivets in this area, taking out the wrinkles with a body dolly and a hammer and installing the skin doubler should be easy.
It actually looks like that would be almost all be hidden by the wing.
