It was a main gear landing at a slow speed. Prop strike, very badly mangled firewa ll 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 int o the pavement. The insurance adjustor come out today and looked it over. H is 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. Lo oks 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 dow n 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 o ften either.- Dan=0A=0A=0A> Date: Sun, 13 Jul 2014 11:28:20 -0700=0A> To: rv10-list@matronics.com=0A> From: dralle@matronics.com=0A> Subject: RV10-L ist: Rusty RV-8 Steel Parts=0A> =0A> =0A> I sent this email to Van's today.

While stripping, I have noticed a couple of things regarding factory powde r coating. Perhaps the most disturbing was the high build up rust under pa rts in certain areas, primarily the ones made from the 4130 plate (see atta ched pictures). This will eventually cause the powder to flake off.=0A> > =0A> >The other issue is the distinct lack of surface prep on all steel par ts! On every single steel part that I have stripped, there is no surface p reparation such as scuffing and/or phosphating. All of my steel parts will be undergoing these steps prior to powder coating for the absolute best po ssible protection from future rust break through. Additionally, the adhesi on of the powder coat is significantly better with these additional surface preparations. The cost differential is minimal, since high-end coaters us ually do these steps by default.=0A> >=0A> >Many builders faced with changi ng the color of their steel parts will simply choose to paint or powder coa t over the top of the factory powder coating.
