The jam nut was still tight so the bearing did not unscrew from the pushrod. I concluded that I had installed the safety wire too tight .. Im not saying it was twisted too many turns per inch, but I suspect that I had stretched it too tight from where it attaches to the end of the pushrod, to the AN4 bolt that captures it at the rod-end bearing. The wire might have become pinched or chafed between the bearing and the Control Column clevis. Or movement of the pushrod and Control Column might impose some extra stretch at certain extreme positions. So I reinstalled the safety wire with a little slack, and its been OK for about 4 years now. --Dave RV10 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=482429#482429 ________________________________ Message 2 _____________________________________ Time: 03:59:37 PM PST US Subject: RV10-List: Re: Elevator Pushrod Rod End From: "Bob Turner" davehead wrote: > The wire might have become pinched or chafed between the bearing and the Control Column clevis.

I think that if you think about this very carefully, you'll see that if the safety wire was installed properly (not pinched by the clevis and rod end) then it does not stretch with control movement. But if it was pinned between the clevis and rod end, then it is possible for it to stretch and also flex with control movement. Do you recall where your wire originally broke? And were you able to pull the wire out of the clevis/rod end with minimal force, or was it pinched in there? I'm wondering if, next time I'm in there, I should back off the jam nuts and re-install with locktite?
