Default HS-702 and HS-00005 flange overlap

While working on my horizontal stab, I trimmed my HS-702 flange in accordance with the instructions on creating the relief holes on the plans (DWG 3). After trimming I noticed that there is still some overlap between my HS-702 and HS-00005 flanges. While the plans do not indicate that this should be. Currently, I have 5/16th inch of edge distance to the first rivet, with a minimum distance of 1/4" required, I would like to avoid reducing that distance any further. Is the overlap okay? Should I trim away more? Can I trim the flange on the HS-00005 to make the the joint fit together better?

I’m having trouble following your description. You shouldn’t have to trim Hs-00005 at all. The forward rib (Hs-0006) does get trimmed to fit between the 710 and 714 spar bars so maybe you mean that?

Pictures help tremendously with a question like this.

Okay, thanks for your patience while I set up a photo site to share my work.

Here is a shot of the area that I was referencing. Notice how the flanges of my HS-702 are touching the flanges of my HS-00005.

Are you applying SB14-01-31.pdf as you go?

Page 17 of the SB shows some overlap....

Brantel makes a good point here. The spar doublers from the service bulletin (which go on the aft side of the 702 spars) will push the HS-00005 ribs aft about 3/32". If that doesn't give you the necessary clearance, then just cut away more of the 702 flange. Take away as much as needed but make sure you maintain proper edge distance on the first hole in the 702 flange. By the looks of it, you can trim a whole lot more of the 702 flange before edge distance becomes and issue for you. Here is a picture of how mine came out. The gap is small, but they don't overlap.

I thought I was, since the kit was new, the directions made no reference to the SB, and the spar doubler came predrilled with all the holes. I was under the impression that the instructions had been modified to incorporate the SB. Is this a bad assumption?

No. You are correct in the case of the HS SB. I would recommend downloading all the SBs and becoming familiar with them. The elevator SB may not be included. I can't remember.
