Really??

I guess some folks were so focused on dealing with the close-tolerance bolts that they forgot the others?

I know somebody who had them missing I believe until the first Annual. I counted my 10 bolts in each wing many times before I moved on. Yikes!

Default photo possible?

thanks Lorne;
I know its difficult, but for us non-builders, sure would be nice to know what we are looking for;
any chance someone ( or Van's) has a photo, ideally with and without the bolt visible?
..and what exactly does it DO?...if aircraft are flying around without it?

thanks

It's quite hard to blame the builders for not putting in bolts that Van's forgot to include in the plans NB the Revision issue of the RV-8 drawing, guess what changed in Revn 1 , and no alert put out to those who were building to Issue 0.

Perry, maybe this will help. I will also try and get a picture of that area out of my build log pictures later. This is plan set 11 for an RV7A.....

Default wing attachments on a 9

For clarification the SB is addressing the two bolts each side (right and Left wing) that can be seen on my 9 only from the REAR side of the centersection spar when you remove the floor panels. These actually along with the spacer stiffen the web in that joint. On my 9 I was a little alarmed when looking from the front and seeing "holes" come to find out there is nothing to bolt to on the FRONT side of the joint. Maybe those get something when you bolt on gear assemblies for the 9A . ONLY on the rear side do you find the two AN 4 bolts that thread into the nutplates in the mid section of the assembly. 75 screws later : Oh well any way the floor panels needs removing and cleaning out as well as a closer look at the control linkage.

Default And I did make some pictures

Send me a text message to 77082334 Twenty six and will return a couple to you. That will be easier than me trying to put pictures on VAF. DRR

Default New Service Bulletin 12/08/12

I accomplished the SB on my -9A today. I verified I had the 4 required AN4-13A bolts and washers on both center wing box locations. I accessed the nutplates from the bottom of each wing by dropping the gear leg to fuselage fairing, then dropping the lower portion of the wing root fairing. With a flashlight I was able to see the described nutplates and 2-3 threads of the described AN4-13A bolts protruding from said nutplate. It took less than 30 minutes to verify and enter in airframe log. Dan

Completed the inspection on my "8" yesterday. There was no way to get in through the fairing slot. Pulled the floor and foot wells for access. The area was very visible this way and all bolts were properly installed.
