BigD Posted August 9, 2019 Report Share Posted August 9, 2019 Old nav light hole replaced years ago by new nav and strobe. They didn’t bother filling hole after installing new one. So, in all seriousness, besides a go-pro camera mount (probably not) what can I put here? Suggestions?

Prior owner Posted August 9, 2019 Report Share Posted August 9, 2019 A nice flush patch... 2 Quote Link to comment Share on other sites More sharing options...
BigD Posted August 9, 2019 Author Report Share Posted August 9, 2019 That was my first idea. Any idea where I can find one or will it need to be fabricated. Thanks!Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Prior owner Posted August 9, 2019 Report Share Posted August 9, 2019 Not sure if they make one ready to order... I’m wondering why they made a new hole for the new unit though...is this a typical installation? Quote Link to comment Share on other sites More sharing options...
jetdriven Posted August 9, 2019 Report Share Posted August 9, 2019 Theres a few ways to do that, but if you really want it clean, a flush patch. 1. 1... Remove pop rivets. Remove nut plates. Dimple skin to a -3 preferrable, or a -4, and fill with cherry flush rivet. 2. 2... Same process, with a -4 or a -5 pull rivet. Youre just trying to fill the hole with metal here. 3. 3. Make a flush patch for the large hole. Make a circular patch, from 2024 .025” aluminum, 3/8” larger in diameter than the hole. Cut a slot from edge to center, to allow you to spiral it into the hole. Put a #40 hole midway between center and OD. Put a cleco in this hole, so you can grip and maneuver the patch. Drill and dimple the patch to match wingtip rib skin with a #40 bit. Cleco into place. Now fill the hole with a patch the same diameter (and thickness) as the hole. Put three #40 holes in a circular pattern, ~3/16 from edge of filler patch. Stay 3/16” away from the slit you cut earlier. Now disassemble, remove the backer patch, deburr and dimple all holes. Then reassemble, cleco together, and fasten them all together with -3 cherry flush pull rivets. If you do it well, it gets very flat. . Some epoxy and micro filler it will disappear. o Obey the AC43.13 rivet spacing and edge distance guidance. 4 Quote Link to comment Share on other sites More sharing options...

Even better, go to AC 43.13-1B P 4-32, Fig. 4-16 (b). Patch "K". I've made Patch "H" a couple of times, and "K" is simpler and smaller. Might be tough getting a bucking bar in there, though. I think I'd get more creative and put a camera mount or something else useful in there. Whatever it is, though, shouldn't interfere with the rear viewing angle of the strobe. Def plug the holes to keep the critters out, though. Quote Link to comment Share on other sites More sharing options...

MB65E Posted August 10, 2019 Report Share Posted August 10, 2019 LAU-57/58 missile rail! It’ll mount right up! New Aveo wingtips! Flush patch per Byron, scab patch with pk screws, Aluminum tape, reflective vinyl sticker, monokote tape, 400mph duct tape, or clear shipping tape for inspection purposes. :-) -Matt Quote Link to comment Share on other sites More sharing options...
N201MKTurbo Posted August 10, 2019 Report Share Posted August 10, 2019 Remove the light, drill out old nut plates, cut out a piece of 020 the exact size of the wingtip. Buck 6-8 flush rivets around the edges and replace the light. The sheet metal will be purely decorative, but I bet nobody would notice it was not factory. 2 Quote Link to comment Share on other sites More sharing options...

If it's a decorative coating it's Preventive Maintenance and can be done by the owner. 1 Quote Link to comment Share on other sites More sharing options...
Niko182 Posted August 10, 2019 Report Share Posted August 10, 2019 I think the cheapest option obviously is 201 wingtips. 1 Quote Link to comment Share on other sites More sharing options...

M20F-1968 Posted August 10, 2019 Report Share Posted August 10, 2019 This can be closed with a nickel and dime patch. Any competent A&P mechanic can do it according to AC 43.13. Or, you can see if the factor has that part and just replace the end cap which may be just as easy. John Breda Quote Link to comment Share on other sites More sharing options...
