Hi fellow canucks...question for you

I’m eventually going to register with the mdra ... but till then...

I’m building a plane with aluminum wings...

I heard you can’t prime the alluminum surfaces because the mdra wants to see the factory spec marks on the aluminum

Any of you that have gone through an inspection on an aluminum plane... love to hear your comments and tips with working with the mdra

Thanks

I don't know if you have seen this site,Inspection Documents, and I can't say for sure, but I would think that having the certs for your material plus having a few scraps with markings should satisfy any inspector. I personally think that aluminum should be primed, both sides, unless you are going for a polished exterior.
