| Subject: | Welding Equipment |
I do a fair amount of welding and I really prefer my Mig, I have made
body repairs, built three trailers and have worked on several other
projects as well. It does not take all that long to learn to weld with a
mig and once you have some practice you will be proud of the welds that
can be done with it. My favorite programs, Chop, Cut and rebuild, Two
Guys Garage and Orange County Choppers often use Mig's for fabricating
structual components, they also use a TIG but not to the same degree. I
have welded with a TIG and would love to have one but I can't justify
$1800.00 for a decent one. My MIG cost a little over $500 with gas,
however it is more difficult to weld aluminum with it but I have seen
others do a great job. I also have gas and arc welders, but seldom use
them.
Regards
Clyde Barcus

A 601XL crashed in north central Arkansas yesterday, http://diamondpilots.blogspot.com/2009/11/plane-crash-in-fulton-county-arkansas.html. Can anyone get to the crash site to get photos? It could take a long time to get anything via NTSB. This seems to have some of the characteristics of an in-flight breakup. There is not much impact damage on the ground, it landed upside down, and the wreckage is very mangled.

| Subject: | Re: 601 nose gear |
This is the way to go with the nose wheel fork :The Storm 500s gear has been developed
to allow grass-field operation, and the direct linkage steering nosewheel,
provide remarkably precise ground handling and steering.
The brakes are actuated by toe brake pedals which are attached to the rudder pedals.
The master cylinders with reservoirs are connected to the pedals on the
pilot side, and standard master cylinders are on the passenger side. No additional
brake fluid reservoir is used. Brake lines are made of clear heavy duty nylon
tubing. This makes it easy to bleed the brakes and very easy to install and
remove the lines.
The nose gear is steering through a 22 degree arc each side of centre by the use
of the rudder pedals. Steel 3/8 inch diameter rods connect the rudder pedals
to the nose wheel. This gives the aircraft accurate and tight steering. The nose
wheel design is unique in that it is very simple. The nose wheel strut is
held in place with two large nylon bearings, impregnated with oil. The lower bearing
is machined so that the strut "self centres" which also centres the rudder.
The nose wheel is attached to a inch thick aluminium wheel fork which is
bolted to the nose strut. The nose strut is 2 inch diameter 4130N steel tubing.
The result is an all around extra tough nose gear assembly which has no O rings,
back-up rings or gaskets. Additionally, no shimming is required.

I looked at the photo posted by the newspaper, and saw a couple of
things that might be interesting:
1. There didn't seem to be any fire. That is good news for accident
cause determination.
2. I didn't see any wings in the picture. I did see what looks like
the tip of the horizontal stabilizer.
3. It looks like there might be a sizeable radiator near the nose
gear. So it probably has a water cooled engine.
I know this is not much, but it is all I could get from the
photo. The police report says there was only one person in the
plane, but I don't consider this reliable information. If I
understood the latest information available it seems like all the
wing separations happened with two people in the plane.
I'm sure the accident investigation folks will have a lot more good
information for us in a few days.

They didn't quite ground it. They "strongly recommended" that the aircraft
not be flown again until the necessary modifications are made.
AMD has not issued the safety bulletin yet. Since there is no safety
bulletin yet, it's still legal to fly the SLSA version.
I'm told that it's been in development for a while, but know nothing about
it. I'll be calling the factory Monday to get the scoop.

Larry,
No reason to get o defensive. Sorry for not signing my name. It;s Hans van Riet.
And the way I read the FAA bulletin, it is grounded. It strongly recommends
to comply with the mods. And it further states that you can't fly if you know
that your aircraft is not airworthy. But to each his own interpretation.

Hi Larry,
I read the SAIB as saying the fleet is either grounded (S-LSA) or
should be grounded by owners/operators of E-LSA and E-AB planes.
The language is not quite as clear as normal humans would prefer. I
think the reason is to really "Ground" the planes the FAA would have
to go through a year long (or longer) process of NPRM and public
comments before actually issuing a rule. This language is about as
strong as they could use. Instead of saying it is against the law to
fly the planes, they imply that any pilot who flies one of these
planes is in violation of FARs.
I think it is very significant that they include 650s along with
601XLs in the SAIB. That means all the effort by the various
companies to make the problem go away by changing the model number
amounted to nothing.
Apparently this has been in the works and the release date was
influenced by the accident in Arkansas. I am sorry it took another
fatal accident to get this moving, but I am glad the fixes for the
design problems are now to be made available to us all.
I presume the companies, AMD and ZAC, will make the design changes
available soon.

The SAIB says that FAA "strongly recommends" the fleet be grounded. However,
it does not say the fleet *is* grounded.
I expect that AMD will issue a mandatory safety letter first thing Monday
morning grounding the SLSA fleet. That has the legal force of an AD. The FAA
cannot issue ADs against SLSAs, according to the folks from the LSA group I
asked at Oshkosh.
However, SLSAs may be legally flown until that happens. This is not just of
academic interest to me: I had a trip planned for tomorrow. As it happens,
it got called off for other reasons.

I hope so. The question I have for you, Paul, is: Will you accept the changes
as AMD issues them, or will you insist that they include other changes if
you don't think they addressed the issues?

Hi Jay,
I can't answer your question until I actually see the
changes. However, I believe I will implement at least some of the
changes and then proceed to have my plane inspected and into phase 1 testing.
My position has always been (since the NTSB letter) that I wanted
official changes for the aileron mass balance and control sensitivity
issues. I am not particularly concerned with the airspeed
indication, but I will seriously consider any proposed change
there. I think it is safe to assume I will consider any wing
structure change as satisfying my desire for aileron balancing. The
desire was based on the NTSB letter and there is now new official
information to consider.
I am hopeful I will have my XL in the air and maybe completely
through phase I before I return my leased plane to its owner next May.

These are things I know as fact:
- Zenair had designed, and AMD has been working on the steps it takes to
make the mods - and documenting the practical aspects of making the
modifications.
- This announcement had been planned to be made by the end of October (and
the FAA has had the documents for a few weeks). Issuing the Safety
Alert/Directive required coordination with the FAA. This was finalized only
in the very recent past. I was told there had been some back-and-forth on
whether unmodified aircraft could continue to be flown at the reduced
performance/weight numbers; with modified aircraft able to move back to the
greater (previous) performance/weight. Apparently, that is not in the cards.
- Kits are being put together now for distribution.
Here's what I don't know: any particulars beyond the spar modifications. I
don't believe the items will match up 1-to-1 with the LAA. The facts suggest
that the real engineering analysis - with real data - has been performed by
the manufacturer and the FAA. Those modifications will be the appropriate
set; not the LAA's, as well-meaning as they are.
With respect to a grounding, the FAA can make a strong recommendation - or
order an emergency grounding; but it's the manufacturer who actually issues
the Safety Alert/Directive, and to which SLSAs must comply. That is what the
FAA bulletin reminds us. Jay is correct. Once (and if) AMD issues a "perform
before next flight" notification (which is what is coming it seems), then
one will need to apply for a Special Flight Permit if one wants to move the
aircraft to a place different from where it is currently located to have the
modifications made.
Let's please try to move past this.

| Subject: | Re: FAA grounds 601 and 650 |
The FAA may be able to ground 601s with S-LSA certificates but they
have no authority to ground all E-AB 601s because there is no type
certificate to take action against. The FAA would have to ground each
individual E-AB on a case by case basis since each one is considered a
one of a kind airplane. Besides which, during phase 1 testing I have
flown my airplane to 4 Gs at a gross weight of 1320 lbs and have flown
it to 110% of my stated Vne. I have carefully and systematically test
flown my plane to the limits of its documented flight envelope and am
confident that it is airworthy if flown within that envelope. I see no
reason to reduce my flight envelope. I am the manufacturer, it is my
decision to make, no one else's.

Late breaking news: AMD just issued a Safety Alert, this evening, grounding
all 601XLs and 650 SLSAs. Zenair is with the FAA and the NTSB at the
accident site.

These are things I know as fact:
- Zenair had designed, and AMD has been working on the steps it takes to
make the mods - and documenting the practical aspects of making the
modifications.
- This announcement had been planned to be made by the end of October (and
the FAA has had the documents for a few weeks). Issuing the Safety
Alert/Directive required coordination with the FAA. This was finalized only
in the very recent past. I was told there had been some back-and-forth on
whether unmodified aircraft could continue to be flown at the reduced
performance/weight numbers; with modified aircraft able to move back to the
greater (previous) performance/weight. Apparently, that is not in the cards.
- Kits are being put together now for distribution.
Here's what I don't know: any particulars beyond the spar modifications. I
don't believe the items will match up 1-to-1 with the LAA. The facts suggest
that the real engineering analysis - with real data - has been performed by
the manufacturer and the FAA. Those modifications will be the appropriate
set; not the LAA's, as well-meaning as they are.
With respect to a grounding, the FAA can make a strong recommendation - or
order an emergency grounding; but it's the manufacturer who actually issues
the Safety Alert/Directive, and to which SLSAs must comply. That is what the
FAA bulletin reminds us. Jay is correct. Once (and if) AMD issues a "perform
before next flight" notification (which is what is coming it seems), then
one will need to apply for a Special Flight Permit if one wants to move the
aircraft to a place different from where it is currently located to have the
modifications made.
Let's please try to move past this.

The SAIB says that FAA "strongly recommends" the fleet be grounded. However,
it does not say the fleet *is* grounded.
I expect that AMD will issue a mandatory safety letter first thing Monday
morning grounding the SLSA fleet. That has the legal force of an AD. The FAA
cannot issue ADs against SLSAs, according to the folks from the LSA group I
asked at Oshkosh.
However, SLSAs may be legally flown until that happens. This is not just of
academic interest to me: I had a trip planned for tomorrow. As it happens,
it got called off for other reasons.

I hope so. The question I have for you, Paul, is: Will you accept the
changes
as AMD issues them, or will you insist that they include other changes if
you don't think they addressed the issues?

Can these drawings be viewed anywhere??? Complete the upgrade by using the
following information:
i. Drawing 6-ZU-1, 6-ZU-2, 6-ZU-3, and 6-ZU-4.
ii. Photo guide with construction standards
iii. Use FAA AC-43.13.-1B and 2A if additional information is required
iv. Use the UK LAA's modification MOD/162B/004 dated 18/08/09 for only
the installation of the aileron counter balance weights. Drawings and
assembly instructions are part of the modification Cheers

Hmm, I've read this three times and don't see how it differs from the design on
the ZAC aircraft (except maybe the 3/8 inch rods). What am I missing?

Subject: Zenith601-List: Re: 601 nose gear
This is the way to go with the nose wheel fork :The Storm 500s gear has been developed
to allow grass-field operation, and the direct linkage steering nosewheel,
provide remarkably precise ground handling and steering.
The brakes are actuated by toe brake pedals which are attached to the rudder pedals.
The master cylinders with reservoirs are connected to the pedals on the
pilot side, and standard master cylinders are on the passenger side. No additional
brake fluid reservoir is used. Brake lines are made of clear heavy duty nylon
tubing. This makes it easy to bleed the brakes and very easy to install and
remove the lines.
The nose gear is steering through a 22 degree arc each side of centre by the use
of the rudder pedals. Steel 3/8 inch diameter rods connect the rudder pedals
to the nose wheel. This gives the aircraft accurate and tight steering. The nose
wheel design is unique in that it is very simple. The nose wheel strut is
held in place with two large nylon bearings, impregnated with oil. The lower bearing
is machined so that the strut "self centres" which also centres the rudder.
The nose wheel is attached to a inch thick aluminium wheel fork which is
bolted to the nose strut. The nose strut is 2 inch diameter 4130N steel tubing.
The result is an all around extra tough nose gear assembly which has no O rings,
back-up rings or gaskets. Additionally, no shimming is required.
