I believe the only reason for opening the hole to 1 inch is so it's a neat
fit over the bushing in the spar itself
That socket is the one with the pip pin installed in it which is supposed to
be packed with washers so the pin doesn't move around guess the logic is you
would just have to pack the pin more if you remove both sides out to one
inch, as you say, though the consensus is that these pins are not
transmitting any lift load, however before the strap around the spars was
added, the pip pin would be stopping the end of the starboard spar moving
rearward under those high lift high drag scenarios that were discussed at
length a month or so ago by everyone when the wing is trying to move
forward, which is why I believe the tie bar was added. So this may be one of
those things that hasn't changed because it doesn't really effect anything
in a bad way if its not altered. So you could probably remove it if you want
to, the manual is quite clear the sockets are NOT structural, just a rigging
aid to help you get the wings on. Feel free to correct me Bud if I got this
all wrong

Subject: Europa-List: Spar socket hole enlargement
The manual says to open up the port spar socket hole to 1" on one side
only, presumably the side facing the seatback. So why not the other
side? If the sockets are non structural, it would seem odd to sandwich
its plate between the bolt head and the spar bushing. What am I
missing here?
