Kyle,
Mine was separated around 3/4 of the weldment bit I saw no visible crack. If you want to see the pics, drop me a PM.

First flight 2011, was a Phoenix based plane. And I am sure this was a manufacturing flaw not a vibration issue. There was almost no weld left after the cosmetic grinding. TT <600 hours.

Talking of things breaking off.....yesterday I had my door strut bracket break off when closing the door. Clean break right at the ceiling mounting point. I will take a pic and post.....Anyone had a similar break?

My 10 steps have have no grinding at all on the weld. Is it possible that the original builder ground them down to make them look "pretty?" They are not the most attractive welds I have seen. This is the first of the issue I have heard on the 10 steps. The other steps are different and had a design flaw. My 6 step cracked in less than 100 hours. However, those crack were always on the steel right near the weld and never the weld itself. They also always cracked on the bottom side and not sure any actually broke off.

Ron, If your strut bracket is an original Nylon bracket from PlaneAround please call me and I'll replace it for free. I originally sold them out of nylon but over time they broke so I replaced them with solid aluminum. Same bolt pattern as Vans and my original brackets. That goes for anyone else reading this. I think I have replaced them all by now but might have a few out there.

I'm with Larry. I've never heard of the RV-10 steps cracking or breaking. I thought the step was redesigned to be more robust for the 10...

The strength of the step is primarily going to depend on how well it was welded. Look closely for examples of an undercut weld. This will be a weak spot subject to cracking with use.

The new steps you get from Van?s are beefed up with extra metal. Mine broke a couple of years back. The new ones are a lot different.

What constitutes "new"? When did the steps change?
