Hi Danny,=0AI 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?- Th
ank you for speaking out on this issue.=0A-=0AJohn Morrow=0A#40461, airfr

t Sunday I was making a routine landing at my home airport and on the rollo
ut 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 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:

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

a less-than-satisfactory result for the reasons outlined above.=0A> >=0A>
