Hi Everyone, as mentioned in a previous post, I am embarking on a almost ground up Eagle II build. I am close to mixing glue and jumping in with both feet after setting up my shop and doing a number of dry assembly rehearsals for joining the upper wing spars.

One of the upper wing front spars has a hairline crack on one side (front-side) which initially I discounted as not worrying about, but then started thinking about possible future ramifications. While I intend to also get an "in-person" consultation, I am including a couple pictures of the suspected area to see what others' opinion might be on using it versus ordering a new one from Aviat (ouch - although rather do it now than later!).

Here are some pictures. You can see where the previous owner tried to wick some CA glue into the crack. I talked to another person and they thought doing that (possibly having a vacuum on the other side) would do the trick. The crack does not go through to the other side. The two spars join and some of the crack is sandwiched with the joining plates, but as you can see it does go further towards the alignment pin holes which is outside of the sandwich. The crack is not continuous although the glue smudges kind of make it appear to be that way.

Thoughts? Thank you!!
