The inboard rib was riveted in place. As with every other rib, every second cleco was removed, the rivet holes cleaned, and then the hole was filled with proseal and the rivet was wet set in place.
One thing I will do completely different on the left tank is the installation of the vent line fitting and the BNC connector. With those already installed prior to riveting, you can't get a squeezer yoke underneath the rivet in those areas. I used my back riveting plate as a bucking bar to get the rivets to set. A pain in the ass, but it worked.
The fittings were torqued to specs. I'll rivet the T-405/410 on the inboard rib as well as the T-410 on the outboard rib tomorrow.
I'm going to do another session tonight and cut out the right wing leading edge landing light and get that prepped. I'm hoping to be close to riveting on both leading edges next weekend.
