Reversing rivet directions for inspection

Thanks,

Looks like Bob already answered the question. Yes, there is now an online form we can use, but you can get an emailed copy of it. A note in your builder log detailing the visit is great in lieu of that.

Thanks, Bob, Vic.

And sorry for thread drift...

It's worth noting that the requirements are completely different in the US and Canada. I'm speaking specifically about the MDRA pre-cover inspection required in Canada - I don't know what the equivalent is in the States, or if there is one.

2- leave the outboard front rib off till after inspection, similar inspection opportunity if inspector balks at looking thru outboard rib lightening hole.
You should strive to follow plans & best practices as much as possible & not compromise to appease inspectors, & push that point to them.

EAA Tech Counselors are volunteers who make themselves available to mentor or oversee homebuilt aircraft construction. You can check EAA.ORG for any near you. In Canada, EAA Tech Counselor visits only add to builder benefit by providing a 'second set of eyes' overview of builder progress & provide some build guidance where needed. These visits do not apply 'credit' towards the Canadian mandatory MD-RA inspections.

This is a good point, I'm going to call the MDRA and ask what they want. I knew there had to be a reason I paid them all that money

I've looked for a nearby EAA tech counselor. Few and far between up here in the Boreal, I'm afraid.

If this were objectively true the HS (specifically on the 14) would need a minimum of two, but probably three, separate inspections. Either that or the inspector would have to inspect the nose ribs, and then stand there and watch me drop in the forward spar and rivet it together. Or, as was my original query, I install some rivets backwards.

My experience was to go as far as I could so he could see all the rivets, them have the pre-cover inspection, and he would allow the part to be completed even though some rivets installed after the inspection could not be seen on the final inspection. Call your inspector as you plan to and ask what he would like.

Your reputation precedes you Ralph, I've actually flown in a plane you built - Shane's Getson's Subaru-powered RV7

I spoke to the MDRA inspector, and sent him page 08-11 from the plans. He said that the rivets below the forward spar should be visible with a mirror and flashlight through one of the lightening holes, and that I should proceed with assembly.
