Covering the butt ribs on a Type III

[Dick B in KY]

Just make a metal plate to cover to forward and aft openings of the butt ribs. Leave the middle open for the sight gauge. I get very little air flow thru there.

Thanks Dick, that sounds like a reasonable solution.

Thanks Dick, that sounds like a reasonable solution.

Edit 1: I just had another question. In addition to covering the front and rear holes in the rib, did you by any chance cover the upper and lower cabin top tubes with fabric? A picture sure would be nice.

Thanks again,

Hi, I didn't close the butt rib, but closed the wing#1 rib with removable thin wooden plates (anything will do - it's just to prevent bugs and birds to get in).
Close the top-tubes, though (see picture - I can't seem to get it upright..)

Here is how the SLSAs are done at least for N703KA

That looks very neat. Thanks a lot for the pictures.

When I built my plane I opted to cover the butt rib with fabric.

Here are a couple of photos to show you what I did.

Wow!, That's pretty sharp. I think I understand what you did.

Thanks,
