I wish I would have tested to find out. Going to have to wait until after its painted, and at that point its not really a great test anymore. Unfortunately, I took it right to the painter after the adjustment on a quick 15 minute flight and didnt check.

Default Old thread, new shimmy.

Resurrecting an old thread here.

I've been flying for about 1.5 years and have *never had a nose wheel shimmy problem. This morning I landed in some moderate cross-wind conditions and the landing was a little sloppy, coming down onto the nose-wheel quickly after the main gear. And there was a shimmy during roll out. The shimmy remained until I turned off the runway.

Several months ago I noticed the same thing. As I recall, that time was something like 10 gusting to 20 all crosswind and I had the same issue. I quickly put the nose wheel down after landing an the nose shimmied during roll out until turn off.

I fly about once a week and apart from these two incidents my nose wheel does not shimmy.

Anyone have any idea what might be going on here?

Have you checked the break out force on the nose wheel? I believe itís very common for it to loosen up, especially during the first year of flying.

It had loosened up but I reset it according to the plans at my annual last August. Both incidence of my shimmy were after this.

Default Anti-Splat Nose Wheel Job

When I acquired my RV-10 almost 3 years ago I also had nose wheel shimmy. As a previous owner of an RV-9A and having done the Anti-Splat nose wheel and main wheel mods, I am a believer in the mod.


I sent my My RV-10 nose wheel off and had the mod performed. Once returned and installed I have NO nose wheel shimmy problems.


Now if there was only enough demand for Allen to be able to tool up to do the mains on an RV-10 I would ecstatic. Until then I still have main gear shimmy issues no matter what I do.

In my case, I've only had a shimmy twice and both times after I let the nose down too fast during a cross-wind landing. And then it doesn't seem to stop until I get very slow and turn off the runway. I'm wondering if it gets triggered by a side load or something like that when it hits the ground. ... By the way, I have the Berringer nose wheel.

This going to be something that isn't uniform across the fleet, but most people should check the nose wheel tension multiple times a year the first few years.

I severely damage my nose wheel pant when the tension had dropped to 13lbs and landed in a cross wind condition. It was the week before my condition inspection for my third year of flying. I had tightened in twice before that and was planning to check again during my condition inspection. The good news is that three years later and it had held it's tension that entire time.

Wow. Thanks for the tip. I'm going to check my breakout force again as soon as possible.

I too had the shimmy and breakout force was correct. Upon lifting the nose (holding tail down with tie-down), I found the entire leg was moving side to side. Ordered and installed a close tolerance bolt from ACS and the problem is solved. The old bolt showed signs of wear. The new one fit perfectly. Currently have 225 hrs on the plane with the Anti-Splat nose wheel bearing mod done since day one.
