I am looking to see if anybody on here has any info on an old spec for wire or a modern equivalent . The Spec. AN-00-W-429 seems to have been discontinued and purged from most record books that I can access. This wire is very similar to piano wire, but apparently is not heat treated after manufacture. The usage in this instance is the diagonal bracing between the spar posts on a two spar wing inside the wing. I found several references to the spec on older wooden aircraft from Beech, Piper, and a bowers fly baby, but nowhere does anybody say what it is, or if there is a modern equivalent. If anybody has a copy of this spec in an old archive and is willing to share, I would much appreciate it. The aircraft in this case is pre WW2.
You are judged not by what you know, but by what you can do.
