| Subject: | Rusty RV-8 Steel Parts and other problems |
I'll give you my tail of woe!
Last Sunday I was making a routine landing at my home airport and on the ro
llout the nose gear departed the plane and then the gear strut stuck into t
he pavement and when the plane continued over it folded up underneath. It w
as a main gear landing at a slow speed. Prop strike=2C very badly mangled f
irewall where the nose gear strut cut into it=2C big gouge on left side whe
re the nose wheel hit fusalage and then into the left flap. All at low spee
d. 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 br
oke at the weld where it attaches to the upright spindle on the wheel assem
bly. 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=2C 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

Perhaps the most disturbing was the high build up rust under parts in certa
in areas=2C primarily the ones made from the 4130 plate (see attached pictu
res). This will eventually cause the powder to flake off.

On every single steel part that I have stripped=2C there is no surface pr
eparation such as scuffing and/or phosphating. All of my steel parts will
be undergoing these steps prior to powder coating for the absolute best pos
sible protection from future rust break through. Additionally=2C the adhes
ion of the powder coat is significantly better with these additional surfac
e preparations. The cost differential is minimal=2C since high-end coaters
usually do these steps by default.

reasons outlined above.
