M20 Ogler Posted August 29, 2021 Report Share Posted August 29, 2021 Removed two old unused antenna plus the cables going to them but have holes there now. How would you patch them? Quote Link to comment Share on other sites More sharing options...
EricJ Posted August 29, 2021 Report Share Posted August 29, 2021 If they're small holes you can put a bolt/nut and some washers there. Quote Link to comment Share on other sites More sharing options...

amillet Posted August 29, 2021 Report Share Posted August 29, 2021 Rubber plug? I used one for the hole for the battery drain tube, which the Concorde doesn’t have Quote Link to comment Share on other sites More sharing options...
Shadrach Posted August 29, 2021 Report Share Posted August 29, 2021 I think a sheet of 2024 and stainless fasteners is best course action. I went through this with an ADF loop antenna not long ago. I used cardboard first then duplicated in 2024, primed and painted. There are perhaps more optimal grades of aluminum for this purpose but my hanger neighbor had plenty of scrap 2024 in his hangar. 1 Quote Link to comment Share on other sites More sharing options...
47U Posted August 29, 2021 Report Share Posted August 29, 2021 Cardboard works well for layout, but I find myself visually challenged. I used a piece of thin plexiglass. My former ADF antenna location had a doubler on the interior, so there were no structural issues. I used 2024T3 as well, .032” I think it was. Mainly because that’s what I had in my work order residue. I used the existing nutplates to attach the new panel. 2 Quote Link to comment Share on other sites More sharing options...
PT20J Posted August 29, 2021 Report Share Posted August 29, 2021 Yep the ADF has a big hole. I had my IA make a round plug and so the patch is flush. He’s really good with sheet metal - I think it took him an hour. Quote Link to comment Share on other sites More sharing options...
Jocbay Posted August 29, 2021 Report Share Posted August 29, 2021 I have been using, on a temporary basis, white gorilla tape. I cut the patches in oval or circular patterns so there is no corner to to start pealing. Man that stuff sticks well! I'm not a fan of those nickel plated plugs. I've seen too many rusty ones. Rubber grommet plugs (perhaps with a bit o silicone sealant) should work, but I really don't want a bunch of black dots on my plane. +1 for the flush patches; but until I can find someone to make them, I'm sticking with gorilla tape. rr Quote Link to comment Share on other sites More sharing options...

I’m plugging a DME hole in the fiberglass belly with a nickel one, but I’m painting it. We’ll see how it holds up. The new engine doesn’t blow much oil, so I can’t count on an oily belly for rust proofing. Skip Quote Link to comment Share on other sites More sharing options...
A64Pilot Posted August 29, 2021 Report Share Posted August 29, 2021 Believe it or not but we used those plug buttons a lot on new aircraft, most are nickel or chrome plated brass, the plain brass are best if you can find them to hold paint. Other wise sand them with an angle die grinder Install them with B2 fuel tank sealer and bend the fingers over on installation and they are a permeant repair 1 Quote Link to comment Share on other sites More sharing options...
