I’m almost ready to start with Proseal!! However, prior to doing that I need to rivet together a few pieces that are outside the Tanks. The picture below shows the 11 pieces (outside the Tank) that need to be riveted together for the Left Fuel Tank.
Below shows the same 11 pieces (also outside the Tank) that need to be riveted together for the Right Fuel Tank.
And here are the two Tank Attach Brackets with all the parts and pieces riveted together.
Next, I riveted the five K1000-08D nutplates to each Fuel Tank Inboard Rib-Aft. The plans indicate NO SEALANT is required for the installation of these nutplates.
The Left Inboard Rib shows the shophead side of the rivets with the nutplates installed (internal part of the tank) and the Right Inboard Rib shows the manufactured heads of the rivets (external part of the tank).
