To determine the critical edge distance for the rear spar fastener, it is necessary to ensure the wing sweep and wing tip distance to the center point of the base of the VS on the fuse are 'equated'.
It's possible for the wing to have no sweep, but be miss-aligned to the fuse so that the measured distance from the wing tip to the VS center point is not the same. This turns out to be the case here. I have a variance of roughly .75 inches for the distance comparing the left and right wing...
The left wing needs to move forward, the right wing backward to get at a maximum .5" of variance.
