Default Need plan to repair RV-6 wing..

Hi guys ! My friend had a small badluck with his RV-6 and we need to repair the leading edge of the wing. My friend didn't build the plane and he doesn't have any plan. I build a RV-7 so i don't have the RV-6 plan too.. Did someone have the RV-6 wing plan in PDf so we will be able to find the right number for the parts we need to make the repair... You can send me the file directly by e-mail : info (at) mraerodesign.com
Thanks

You can get a complete set of plans and the construction manual from Van's on CD/DVD for like $10. I'd recommend this as the -6/6A plans aren't as complete as the 7 plans are and you might need to reference a number of different drawings.

Just a heads up on the 6. Unlike the 7, the early 6 did not have prepunched holes in the skins, if memory serves me well, the late model 6 had some prepunched skins. You may have to use the damaged skin as a template for drilling??? You might want to verify with Vans using the serial number of the kit. Larry

Thumbs up

Very thin clear Lexan works real well when making these types of repairs for locating the holes and rivet layout/spacing. You can cleco it in place like the skin material and eventually end up with a final pattern copy.

Default What we want to do

We plan to make the repair like on this pics :


We will buy one rib and the front skin to have the correct curve. We don't know if it's a pre-punched wing and I think it will be less job to make a patch than changing the complet skin...

I have done this repair on an RV-6A once. and multiple times on other models.
My recommendation would be to do the research to determine if the wing kit vintage had prepunched skins. You could probably tell by measuring hole spacing with a caliper. If the hole spacing on different rib locations, exactly matches from one to another, it most likely is a PP skin.
The end result will be much better if you replace the skin and it is not much m more work than patching it. Particularly because it would make replacing the damaged rib much easier. The process does involve removing the fuel tank, but that is not that big of a deal. Once the tank has been removed, I have removed/replaced the (prepunched) skin in about 8 hours.

Default changing the skin

But, did you have enough access to make all the riveting ? How did you acces the rivets of the main spar ? The ones near the tips are not a problem, but for thoses near the center ??

The exact same way as when the wing was originally built...

With the wing tip removed, you can access the outboard portion of the wing spar flange, and the inboard portion is accessed just like had to be done when riveting the second outboard skin onto the aft part of the wing, by reaching in through the fwd lightening holes in the main wing ribs from the access cover on the wing bottom.

The same is done for the riveting on the nose ribs. With the fuel tank removed, you can reach half way by access though the inboard nose rib, and the other half through the outboard most nose rib at the tip.

Default Repair

If your skin is not pre-punched and you elect to patch the damaged area. I would use a section of replacement skin to cut backing doubler from. It is the correct thickness and curvature. We know we are not bound by AC43-13 but it has all the good info on how this should be done.

Default part number please.

If someone who have the RV-6 plan can just tell me the parts number for the ribs, and the leading edge skin, this will help me to order the parts. We will order the CD of plan in the same time for the futur, but I want to save time of ordering the CD and wait after it to order our parts....

Thanks
