The entire site seems to be down right now as my normal Matronics bookmark isn't working either. In any event, the pics are the same as the ones Doug posted on the VAF frontpage.

I'll wait awhile and try the server again. I couldn't even get to matronics.com.
Matt's probably working on kit log pro updates and doesn't know his server is down

De Ja Vu
This exact thing happened to me in my 6. I noticed on one flight when I was in Phase One (about 20 hours) my stick in pitch had another 1/8" play. I was very uncomfortable and got on the ground fast. I promised my self before I landed, that I would not fly again till I found the problem. The problem was very subtle. It was so subtle that had I not had so many hours in the plane, I would never have recognized it.
I started my investigation by tapeing the elevator to the horizontal stab. (my assumption was that a rod end bearing had failed WRONG) Everything checked out fine till I removed my floor and inspected the first rod end bearing to the push tube underneath my sticks. There was NO NUT or WASHER on the number 3 bolt that went through the rod end bearing. The bolt had partially slipped out and was wobbeling since I no longer had a double sheer attach any more.
So how did this happen and why didn't anyone catch it? I installed my wing leveler on top of the attach point and it was totally hidden from view. Even though I had no less than four inspections by highly qualified people, no one used a mirror and inspected that particular attachment. In fact I did such a thorough job of inspecting and correcting before before any one else inspected that there were only a few minor squaks.
If I had continued flying the plane and ignored a seeming minor problem, at some point I would have had A VERY BAD DAY.
Hopefully these 2 events will save someone else of the same event or worse.

Steve, do you think the nut and washer were never actually installed, or do you think they backed off somehow?

There are several "Jesus" bolts in the RV series and this is one of them.
In all my years of working with nylon and metal lock nuts, if it was servicable when it was installed and properly tightened it was not going to back off and I never saw one back off. In the RV-10 it is not difficult to inspect IF you have ALL the panels off for inspection.

Is this only in the -10 plans? I don't recall ever seeing the bearings having safety wire. Thanks to Adam P. for posting the image of the plans. You can clearly see the safety wire around the bolt where it could pull out of the pushrod. I don't think that's in the -7 plans.

Never installed
Bevan, There is no way that a properly installed nut would ever come off.

Safety wire
Safety wire is installed to keep the pushrod from rotating
For whatever reason on the RV10 only.
It has no bearing on the safety of the nut and bolt.
