My RV-10 left aileron jammed at full deflection!

To see a number on photos showing preparation and finished welded push rods go to my post here, along with a number of informative posts regarding the process.



I have been flying with these in my RV-7A for six years now with no issues.

There's certainly nothing wrong with welding them in, but the riveted versions will work fine, too. Regardless of how they're attached, you *still* have to ensure that there's no chafing or binding anywhere, and that may require relieving one or more pass-throughs throughout the airframe. You just may have to relieve it a little more if the rod ends are riveted in, that's all.

Welding won't obviate the need to ensure the systems is free of chafe points or the like.

I think it just did - at least once. Way to go DCBrown.

So If I have them welded, can I proof load test them?

How much weight should I hang from the ends to proof test the welds?
what is twice the expected flight loads in tension?

Thank you Jim. I appreciate the pictures and link to the other thread.

Here’s the Airbus tube I was talking about.

Wow, are there rivets all the way around, 90 degrees apart, staggered 45 degrees between the inner and outer rows, for a total of eight rivets?

I wonder if welding of the control pushrod is a non-standard aviation practice. It seems using rivet is standard, and according to Vans and Airbus. I wonder if Mel will ding you if you weld.
