| Subject: | Center section wing bolt alignment |
Hi Kelly,
After commiserating with you in reading your email, a thought occurred to me.
I had purposely forgotten about this so as not to have continuous bad dreams about
it. So here is the question: Do you have the same serial number fuselage
as you do wings? As in, are the numbers matching? As in, were you one of the
unfortunate ones that lost your quick build in the Philippines weather disaster
some years ago???
If my memory serves me correctly, I was told that if the numbers were matching
these two parts were match drilled or drilled together. But I was also told
from Vans that they were drilled with such precision that even if they were not
match drilled you could have two different serial number wings and fuselage
and that they would match just fine. On a positive note, I do remember one builder
sharing that his did not match and all went together just fine. But, maybe
there is more to that story
Just food for thought in case. I am only weeks behind you in fitting and it was
just last week that I was looking at my serial number on the fuselage spar
connect and looking for my build serial number only to see it not match. What,
I said? And then I remembered, I was supposed to forget that!
Check it out and see what you find. Probably more than one inquiring mind would
like to know! And if the different serial number issue is not the case, we
will still be anxious to hear what you found and did. Enlarging holes is cringe-able
to say the least. Building another wing is Super cringe-able.

I talked to Van's about this a few months ago. They don't match drill the RV-10
spars to the center sections. Their CNC us accurate enough that they don't need
to.
The problem is that the center sections were not bolted together with the spacers
when they were assembled for riveting, so they don't align. Or, one of the
parts is drilled or bent wrong so they don't fit right. It is definitely a problem
on Van's part. I have never seen one that didn't align, even I planes assembled
by people who had no clue what they were doing, so I assume it's a bad
part somewhere in there. This should have been checked as it was being built.
Inspect carefully the internal structure and see if any rivets are broken or sheared,
if any skins are wrinkled ever so slightly. It could have been tweaked
in transport.

I will check, but the wing # vs fuselage # is irrelevant in this case.
It is the two halves of the center section on one side of the fuselage
that have the misalignment. At this stage the wings are not involved.
Unfortunately my QB was one of the first to come out of Manila after
relocation/reorganization of the facility their. There were a number of
QC issues right from the start, like not countersinking the longerons
before riveting on the dimpled skins.

I had QB wings with legacy fuselage and they were NOT a serial number pair, and
it took very little effort to match them up.
On one wing we used a lubed taper pin patted softly with rivet gun on a couple
of holes, but the next time it all went really well. I too had to file a little
on the outer sandwich plate on a couple of holes. Sometimes I think it is kind
of an optical illusion when they appear misaligned. At one point in final
assembly we thought we had a misalignment, until we rembembered that they had
already been together once. Just a guy moving the wingtip slightly seems to
make a significant difference in the alignment of the holes.
I never touched the factory bolts until the day they went in for good. We froze
and lubed them, but they went in with very little rubber mallet encouragement.
Most went in with just finger pressure.

Jesse,
I see your point. Also I see that my comments dont even apply since I obviously
didnt read into the problem well enough. The problem appears to present itself
with the bolts not aligning (wont go through the fore and aft holes) before
the wing is even attached. Therefore only your comments and ideas apply here.
And, I cant come up with any other scenario other than what you said: shipping
damage or disfigurement during transportation, riveting done without alignment
bolts installed to begin with, etc
