| Subject: | N414PZ Landing incident |
--> Zenith-List message posted by: "Paul Hartl" <paulhartl@cox.net>
Last evening, as I made a nearly calm-wind landing at KSUN, my 34th
landing in 601HDS N414PZ, I heard and felt unpretty sounds and
vibrations from my right main wheel. It wasn't violent, but it was
distinctly not right, either. As I limped back, slowly, to my tie-down,
it became clear that I wouldn't be doing anymore flying for a while. An
inspection in this morning's light revealed detroyed bearing parts
hanging out on the axel, which, upon removal of the wheel revealed a
most unexpected sight. My main wheels - made by Matco and supplied as
part of my kit by Zenith in June of 1998, did not contain the tapered
roller bearings that my Matco drawings show, but instead contained ball
bearings! According to the Matco instructions that came with my wheels,
the front wheel contains ball bearings, but the mains contain tapered
roller bearings. A mixup, perhaps? Not on my part - because the front
wheel doesn't have the weld points for the brake rotor - only the mains
have these, so it wasn't me that mixed up parts - this must have
occurred at Matco. I doubt if Zenith knew (or even could have known),
as they probably don't look much different from the outside - but this
is just one more example of poor Matco workmanship. So beware Matco
wheel owners - these are crappy products, and I am none to pleased to be
using them on my aircraft.
I will be talking to Matco on Monday, and will report back to you then.
Oh, otherwise, she flies great!

--> Zenith-List message posted by: "Bill Denton" <bdenton@bdenton.com>
What is the current thinking regarding the use of an electric fuel pump as a
backup to the mechanical pump on the Jabiru 3300?
Are most builders using a backup pump?
I have noticed that on most fuel system schematics I have seen, a check
valve is used on the outlet side of the mechanical pump to prevent the
electric pump from forcing fuel backwards through the mechanical pump. Is a
check valve also required on the outlet side of the electrical pump?
On a related not, I have noticed that in most low-wing aircraft that I have
seen, the fuel selector valve only permits a choice of left tank/right tank,
while many high-wing aircraft allow a choice of left tank/right tank/both
tanks.
Is there some reason why left/right/both selectors are not used on low-wing
airplanes?
Thanks...

One more part that died:
Sometime in the last 4 hours of flight, the antenna for my Ameri-King
AK-450 ELT broke off - on its own. Aren't these things were supposed to
be able to endure a crash landing - I mean, isn't that the point of them
being required? Now, it is true that not every one of my 34 landings has
been a greaser, but none have even remotely approached crash status!
What's more, the same thing happened to Win Ellis's AK-450 antenna on
his 701, even earlier in his flight testing. So how do these things get
OK'd for use, anyway? Doesn't the FAA, which requires that I buy and
install an ELT, bother to look into the quality of ELTs, even if they're
not for certified aircraft?

Bill,
Jabiru recommends an electric back up pump plumbed in series. We use
"Universal Electric Fuel Pump" frokm NAPA of Advance Auto Parrts. It's made
by Facet. Use the one with th lower pressure output of about 2 to 4 PSI

My AK-450 ELT antenna is easily pulled from its base mount and I don't see
any method for tightening it so I elected to use a second bent whip antenna
instead of the one supplied with the unit. It was in this condition on a
new 2005 unit out of the box.

Paul,
I'm seriously pleased to hear you were able to make the trek back to
your tie-down without damaging
the strut plate or worse, dropping a wing. Such a mistake is outside
the classification of poor workmanship
and definitely a factory recall error. I'm sure that Matco will make it
right and when your anger subsides
you'll find they are pretty good people to deal with. I just hope not
too many more are found that way. Now to remove
fairings a third time this week to check each wheel to see what's
inside. I made a quick and inexpensive
lift last year that may assist Matco users in raising the fork to remove
a wheel during the annual. See link below.

50/50 is what I'm using, however, according to the instructions, even

Hi Paul,
Thanks so much for the heads- up on the bearings. You really have me
paranoid now since Jim in North Carolina had a gear leg weld break and
lost a wheel on landing a couple of weeks ago! Please let us know what
Matco says or offers.
If there is any external way to tell the bearings apart without
disassembling the wheel. I really don't need another thing to worry
about with rolling parts. Last night my Matco brakes let me down and I
coasted thru a fence and am doing a main wing skin replacement today.
It's not been a good month for Matco/ZAC users in the wheel department.
Thanks

| Subject: | aileron hinge conversion |
--> Zenith-List message posted by: ron dewees <rdewees@mindspring.com>
Hi listers,
My 601 HDS is down for some maintenance at the time and I have been
giving some thought to converting from hingeless to hinged ailerons.
Don't get me wrong, I have no particular complaint with the hingeless
aileron and think it will last into the next century. I do think it's
stiffer than a hinged aileron and that my ailreon trim is almost useless
because it tries to work against the friction of the wing skin rather
than hinges like the elevator uses.
For anyone who has converted from hingeless to hinged, what has been
your experience, was it worth it, and what kind of piano hinge did you
use. It looks like you need a wide hinge to reach the two rivet lines
and even then, will need a third rivet line to secure the overlapping
edges of the old aileron skin.
Pictures or comments would be very welcome.
Thanks
Ron 601HDS

ZAC sells it to their customers, as I'm sure other list members will
tell you. But I have had an excellent relationship with the following
supplier --
Century Corrosion, http://www.centurycorrosion.com/
Terry Clinkenbeard ( TerryC *at* centurycorrosion *dot* com )
I believe they sell Cortec 373 in 1-gallon quantities, and at a
competitive price. They were extremely helpful in providing
information and getting the Cortec factory to send me a free 1-pint
sample for some experimenting I needed to do. Highly recommended.

Mine fell apart when I lifted the antenna up to measure the coax length.
I superglued it back together and it seemed to withstand a reasonable
pull test.
They also sent it with the batteries installed and when I opened the
package it was transmitting and the batteries were nearly dead.
I suspect that without the antenna hooked up that it did not put
out much signal. A call to SAR in Trenton confirmed that they
did not hear it.

I bought mine from ZAC when I bought the kit....I am not sure if you can get
it from Aircraft Spruce or Wicks.
The website www.cortecvci.com has an 800 number but does not list purchasing
info (that I could find)
Good Luck

--> Zenith-List message posted by: "Gary A. Boothe" <gboothe@calply.com>
Listers,
I am considering building my metal fuel tanks using the flanged, riveted method
as described on the EAA Homebuilders site. Anyone have some insights on that?
Obviously, I am aware of some of the benefits of welded joints, so I would like
to focus on the successful applications of rivets and sealers.

I'm a 701 kit builder, currently working on wings (anticipating Rotax ULS). My
goal is to fly with amphibious floats, which I already have. If I skipped
the wheel's-only phase might there be one less FAA sign off and less hassle with
reconfiguration. I'm a private pilot working on seaplane rating.
Any experience with this?

Paul,
As I have been told the story, the assets of MATCO were sold to a new
owner during the year 2000. I have wheels that predate that too. You can
find my difficulties with the three bolts that hold the two halves of the
wheels together in the archives. But I received excellent support from
George Happ of MATCO in resolving the problem. George also has addressed
the "weak brakes" complaint explaining the problem, building a demonstration
prototype, and offering multiple solutions.
Overall, the pre-2000 wheels seem to have some lingering problems with
bolts, bearings, and the Zenith pedal design that all builders should be
aware of.

This summer the engine has been performing reliably, but altogether I still
only have about 40 hours on it. I believe that the CAM100/125 engines are
an excellent concept, but my particular engine has had some quality control
issues that have caused me a lot of lost time over the past few years.
I think it would be too heavy for the 701. The total installation of the
CAM100 works out to about 80 lbs heavier than a Rotax 912.

One more part that died:
Sometime in the last 4 hours of flight, the antenna for my Ameri-King
AK-450 ELT broke off - on its own. Aren't these things were supposed to
be able to endure a crash landing - I mean, isn't that the point of them
being required? Now, it is true that not every one of my 34 landings has
been a greaser, but none have even remotely approached crash status!
What's more, the same thing happened to Win Ellis's AK-450 antenna on
his 701, even earlier in his flight testing. So how do these things get
OK'd for use, anyway? Doesn't the FAA, which requires that I buy and
install an ELT, bother to look into the quality of ELTs, even if they're
not for certified aircraft?

Mine broke off on the second flight of my 801 here in Jackson Hole. It is somewhere
in Grand Teton park scattered among the sagebrush. I did email Ameri-King
but got no response. Since this seems to happen all the time I guess the: "do
not archive" will do. I did test the unit on my last annual and it does send
a very strong signal without the antenna installed...

| Subject: | Wheels or floats first, 701? WHEELS |
--> Zenith-List message posted by: "Chip W. Erwin" <aircraft@czaw.cz>
I suggest to all our float customers to learn to fly the aircraft very well
on wheels first. The 701 has excellent STOL performance which takes some
time to master. Flying on floats changes the aircraft parameters
significantly. By knowing how to fly on wheels you will have an easy
transition to floats. And as far as I know, no further FAA inspection is
required to add the floats.
