I did it! I finished the left side horizontal stab.
Here's the end rib all clecoed and ready to rivet.
It's all put together for the first time. Looks good, huh? (this is the left side but upside down)
I was going to rivet on the trim tab control horn...but...as you can see, it doesn't exactly fit! I checked and double checked the part number and this is indeed the correct tab. Looks like another call to Rans.
UPDATE: I called Rans and asked about this trim tab horn. This trim tab and horn were changed when they went to the new Sport Wing and they mistakenly sent me the new tab but wrong tab horn. A new one is already on the way to me!
