The same thing happen to me and I remember being pretty sick about it. I actually happen to be traveling by Van's at the time and stopped in to see them. Below is a picture of what they approved, you have to have a shim anyways, this is just a enlarged version of it tying everything together. I remember the engineer saying that it was over kill, but better than replacing parts.

Default Approved fix...

The fix that Vans tech support suggested was similar to the fix that Steve took.

They said the following.

Make a triangular gusset and use that on the top of the deck to replace the spacer that sits underneath the HS-908 attach angle. Make the gusset big enough to take in one rivet in front of the attach angle and one rivet inboard of the attach angle. They also suggested filling the extra hole with JB Weld, not to increase the strength of the longeron or angle underneath, but to provide compression against the bolt. They said the forces in this area are downward.

They said for a cleaner fix I could also replace the angle underneath, but that it was not necessary.

I'm currently stewing over whether I am going to replace the angle underneath. I cannot possibly see how I can drill out the rivets that attach the angle to the bulkhead without removing the deck. I put the manufactured head on the aft side of the angle and bulkhead on the two outer most rivets. Accessibility to the manufactured head of those rivets is nearly impossible. All the rivets on the deck are very accessible and should be easy to drill out. But there's always a chance of messing up a few of those rivets.

This fix is specific to my mistake. I would not suggest anyone use this same fix without consulting with Vans.

Thanks for all the input,
Michael-

Default Fixed...

I finally finished the fix today. I've been traveling a bit and so this task got strung out a bit.

I'm very pleased with the results. I did decide to replace the angle. I removed the top deck which went very smoothly. No enlarged holes from drilling out rivets. Then I removed the old angle. I filled both holes (the small angled pilot hole and the bolt hole) in the longeron with JB weld. Later I re-drilled the bolt hole so that JB weld only remained in the angled pilot hole.

I fabricated a new angle and installed it. Before re-installing the top deck, I fabricated the gusset. Actually I made one for each side just so they match. It looks nicer. I then match drilled the gussets to the top deck so I didn't have to back drill through the holes to install the gussets.

I then re-installed the top deck, and finally installed the gussets.

Here's a couple of photos.

Very nice job with this. Wouldn't your HS seat on that one single rivet next to the bolt holes? If memory serves me right, there may be a bit of interference and you may need to replace those two rivets with flush head rivets.

Default No interference...

I just bolted the HS to the tail. I don't have an interference problem with the rivets you mention. I can easily slip a piece of card stock in there.

Thanks,
Michael-

A long way from that first post, huh Michael?! Nice job. Looks great. Also cool that someone from Van's was able to allay your fears early so that you didn't have to sweat it all weekend!
