I'll give you my tail of woe!
Last Sunday I was making a routine landing at my home airport and on the rollout the nose gear departed the plane and then the gear strut stuck into the pavement and when the plane continued over it folded up underneath. It was a main gear landing at a slow speed. Prop strike, very badly mangled firewall where the nose gear strut cut into it, big gouge on left side where the nose wheel hit fusalage and then into the left flap. All at low speed. Gas everywhere. I was fortunate that it didn't roll over when the strut dug into the pavement. The insurance adjustor come out today and looked it over. His opinion agreed with me as to cause of accident. The gear strut broke at the weld where it attaches to the upright spindle on the wheel assembly. Looks to be a very poor weld and not a very robust design to boot. The weld was very small in width and didn't penetrate very deep. Split right down the middle of the weld, I wonder how many ticking time bombs are out there ready to blow off the nose gears. Not in a place to check very often either. Dan

Hi Danny,
I would like to examine my nose gear for the poor weld. I am not sure what weld you are talking about. Is a picture available? Thank you for speaking out on this issue.

As you can see the weld fillet is VERY small and the weld didn't penetrate very well.

>Dear Van's,
>
>I am stripping all of the steel parts on my RV-8 to have them re-powder coated in a textured black to match the rest of my interior. While stripping, I have noticed a couple of things regarding factory powder coating. Perhaps the most disturbing was the high build up rust under parts in certain areas, primarily the ones made from the 4130 plate (see attached pictures). This will eventually cause the powder to flake off.
>
>The other issue is the distinct lack of surface prep on all steel parts! On every single steel part that I have stripped, there is no surface preparation such as scuffing and/or phosphating. All of my steel parts will be undergoing these steps prior to powder coating for the absolute best possible protection from future rust break through. Additionally, the adhesion of the powder coat is significantly better with these additional surface preparations. The cost differential is minimal, since high-end coaters usually do these steps by default.
>
>Many builders faced with changing the color of their steel parts will simply choose to paint or powder coat over the top of the factory powder coating. This will eventually lead to a less-than-satisfactory result for the reasons outlined above.

>FYI.
