If you could accurately bore the hole bigger and put a bushing in while maintaining the recommended edge distance it might work but that's hard to do on the airplane. I'm flabbergasted that somebody built that and went and flew it. Wow.

Does one have to remove the wing to discover thing slike this? If you were going to buy a -4 is there a way to catch this in an inspection?

Two thoughts for you.

First, make sure you wrap the main spar in plastic (cling wrap might work) to keep dust and dirt from getting between the spar laminates.

Second, ask Van's if you can have someone weld the hole close and then re-drill it.

Save the effort - no way can you weld this and retain enough strength to be safe. Not a chance.

There is an AC43.13 reference that advises not to heat aircraft grade aluminum past 212 degrees to prevent adverse effects on the temper.

You can weld castings and thin sheet used for fairings and non structural parts but not on something like this, where the strength comes from the heat treatment.

Thanks guys. I will contact Van's just to get there two cents, but I think they will agree with you guys. The only way I see to fix it without replacing the whole piece is to updrill it. I will have to check on the edge distance on that. Does anyone know what is allowable?

He is a lucky guy i would say....I wouldnt knowingly fly it for 5 minutes with that notch in the rear spar attach hole. Cant tell for sure but it looks like they just riveted a small section on where the hole is vs the complete doubler?

I would look at the bolt holes attaching the empenage too. If the qualty of that hole didnt matter to the builder I would be concerned about other critical points. Did he build the spar?
