Pre/Post War Wings

Re: Pre/Post War Wings

Before a lot of peoples heads explode, Mike is right about wing applications. The first stamped rib wings were made in 1945 and you aren't "supposed" to put them on a pre-war without paperwork. That said, there are a LOT of pre-war planes with stamped ribs and a few post war planes with stick ribs out there. They aren't legal without the proper paper, but where will you find an A&P/IA who knows the difference? Your plane isn't going to fall out of the sky because you have stamped ribs on a pre-war plane, but you SHOULD quietly get the paperwork put together to make it legal.

I don't have the drawing to look it up, but I would think that the 15 rib wing with stamped ribs is approved for the previous model airplanes. The drawing would show what model it is approved for. If you ordered a wing from taylorcraft in 1946 for a prewar airplane I doubt that they had a special stash of truss ribs to build one up.

Re: Pre/Post War Wings

There is a letter posted in the tech ref. section that says the post war ribs are interchangeable with the pre war ones. Tim

Re: Pre/Post War Wings

If you have a copy of that letter in hand and your IA agrees the only reason I think you should use the stick ribs is if you are a stickler for originality. Save the stick ribs for the (slightly more than) half crazy among us who want them. As far as utility and strength are copncerned, the stamped ribs are FAR superior.
