John, the website I posted a link to does show some of the other chemicals you
mentioned as being bad for polycarbonate but not gasoline, either unleaded or
leaded. I also checked ethanol and it was rated B-good.
Thought I can't see that Cole-Parmer has anything to gain by mis-leading folks,
as we all know, just because we see it on a website does not mean it is true,
so, I'd say it is time for me to do an experiment. Nothing like empirical evidence
to educate and inform.
I still have the windshield that I replaced on our Allegro when it was damaged
mechanically (not chemically) and some drop from the sheet I bought to replace
it with. According to the Allegro manufacturer the material is polycarbonate
with the brand name of Makrolon which is manufactured by Bayer Material Sciences.
The sheet I replaced it with was also the same brand of polycarbonate which
I purchased from McMaster-Carr.
I plan to test both using 93 AKI auto-gas and also with 100LL. If anyone wants
to duplicate this test with a known piece of Lexan (GE product) it would be educational
to us all.
My plan is to cut narrow strips of each and soak one end in each of the fuels overnight
or longer and photograph them afterwards for all to see.

Been listening to this with interest.? Years ago I had an RV-3 with a lexan windshield
and fuselage gas tank filled just in front of it.? The lexan was maybe
15 years old with lots of microscratches from being cleaned and from the stress
of being bent fairly aggressively.? One day I splashed a little autofuel on
it and it became almost completely opaque.? I was told of this incompatibility
which was certainly demonstrated but also think the age and microcracks contributed
to it.? Also, in another project I had used a form of lexan that had
a coating on it to prevent scratches.? I suspect that polycarbonate comes in many
brands and forms, some with coatings and some without, that may have different
susceptibilities to chemicals as well as the age and stress factors.

It will peal off to the left if trimmed to fly hands off >>
What you need is the Hauck patented trimming device.
Obtain a short bungee. anchor one end somewhere on the passenger seat at
floor level. Take two turns around the base of the joy stick and then
anchor the free end close to the starting point..
The elastic should be fairly tight. Adjustment of the amount of input
is obtained by moving the bungee up the stick for more trim and towards
the base for less.
Works everytime. Nothing to go wrong.. Just what aircraft control should
be.

Rather than soaking each test strip overnight in the fuel, test them in a
similar situation as would be encountered in the real world, a spill,
splash, wind bown mist, etc.,
Wipe some off immediately, a few minutes, 10 minutes, and on.
In the real world the windshield will not be in a situation that it soaks
all night in fuel, unless it has an overhead tank that is dripping on it.
My experience with Lexan/polycarbonate damage by fuel, has been random. The
case I mentioned from the fuel spill in Alaska is the only one that stands
out in my memory now. There were others that are too far gone in the
recesses of my poor memory. The spill in Alaska was unknown until I
discovered the damage later, on down the road. So that fuel stayed on the
Lexan until it evavorated.

John,
Per your suggestion, I'll do the short term test first. If no obvious damage, then
I'll do an overnight soak.
I've been googling this morning and found one site describing an Asian car manufacture's
plans of trying polycarbonate as a fuel tank to save weight. This is
getting more interesting the more I dig.
I hope someone with Lexan or another brand of polycarbonate other than Makrolon
which is what I have, will try this test too. Just be certain that it is not
acrylic or other clear plastic.

Acrylic is easy to test. Bend it and it will break. It is extremely
brittle.
I unknowingly made a FS windshield out of acrylic someone gave me, thinking
it was Lexan. I broke in the air. Big piece hit the leading edge of the
wing. Thus my experience with the Old Kolb Co's leading edge dent remover.

I just found this abstract of a study done on the effects of gasoline(s) on various
plastics. Note in particular the last statement in the abstract. Very interesting!
Article
Stress cracking of plastics by gasoline and gasoline components
M. G. Wyzgoski, C. H. M. Jacques
Polymers Department, General Motors Research Laboratories, Warren, Michigan 48090
ABSTRACT
The susceptibility of polycarbonate, polymethyl methacrylate, and cellulose acetate
butyrate to gasoline-induced stress cracking was evaluated by measuring the
critical strains of specimens exposed to a variety of commercial gasolines
and gasoline components. Cellulose acetate butyrate exhibited the greatest resistance
to gasoline followed by polymethyl methacrylate and polycarbonate. Stress
cracking was a complex function of gasoline composition. Measured critical
strains generally decreased and the severity of cracking of molded parts generally
increased as the total aromatic content of the gasolines increased. However,
a significant difference in critical strains was observed between the individual
aliphatic components of gasoline. No correlation was observed between
critical strain and gasoline type, i.e., premium, regular, or unleaded. The effect
of time of exposure was examined, and it was observed that for some binary
mixtures splashing caused much more severe cracking than continuous exposure.

Sorta goes along with what I have experienced.
Some do and some don't, based on additives, and amounts.
Splashing caused more severe cracking.

I fly both a Challenge and a Mk111c/912 I was on the Challenger site for
a long time and I seen
the same thing happen there that is happening here now..back biting and

point on the challenger site I just had all that mail put in the junk
box. Now I check it to see those
that was still interesting in flying and are civil in their comments.
There is a lot of good information out
there and lets face it not ever plane fly's the same even though they
are the same model plus the
fact that where you live the fly's conditions are different and we have
to adjust to them if we want to fly.
Flying some what is like men & women..what works for one may not work
for another...we adjust or

Look at the numbers below the bar-codes. I've been told 700's mean

the US or Canada. Anyone know for sure?

Gary,
Thanks for sharing your story, that sounds like a very close call and potentially
far more dangerous than an engine failure. This is really what this forum
is all about, these recent reports from fellow Kolb flyer's leave no room for
doubt, using cheap fuel filters will likely result in aircraft damage due to forced
landing or may even kill you. Given all the close calls and stories of
cheap fuel filters failing in the last couple days, its nothing short of foolish
for people to keep using cheap lawnmower quality filters in airplanes. Those
that chose to ignore good advice and reports like the one above do so at their
own peril. Here is the URL to the best fuel filter on the planet for an
experimental airplane as far as I am concerned. If someone finds something better
and safer, by all means post it.. This filter is designed to be washed,
will last forever, has zero plastic in it, is ethanol proof, has duel screens,
a larger mesh, and then large area very fine micro stainless steel 10 micron
filter screen that that will filter far better than any fiber / paper element
ever will.
http://www.aircraftspruce.com/catalog/appages/micron10.php
John H,
The story above illustrates a point that you missed yesterday. The fuel filter
you have and recommend is not the filter that is sold today. What someone buys
today is most likely the same type of filter that Gary describes above, a cheap
Chinese copy that is likely to fail. I am not trying to get John H to change
a filter that he has had for 14 years, but I sure as heck would not tell
people to buy the same one, because chances are they cant, and will end up with
something dangerous.
John, your fuel filter record is pretty good, and I am not trying to get you to
change yours, because I know you wont. My posts are for others out there that
don't have your filter which I consider to be OK and safe, but not great...
For the record but there is still one engine failure you talked about yesterday
in your 912-S where your fuel filter got completely clogged with fibers cutting
off your fuel supply. This engine failure may not have happened if you had
a filter with a larger filter area, just speculation, we will never know for
sure. What I do know is that I spent close to 20,000 dollars for a reliable
aviation type engine, and that spending this type of money for an engine and
then having it fail due to using a cheap lawn mower type filter is nothing short
of crazy. Given all the cheap copy's that are being made of your fuel filter
and problems with them out there John H, do you really think it is good advice
to tell people they should go out and buy your type filter ?

Subject: Kolb-List: Re: polycarbonate/gasoline myth buster
I just found this abstract of a study done on the effects of gasoline(s) on various
plastics. Note in particular the last statement in the abstract. Very interesting!
Article
Stress cracking of plastics by gasoline and gasoline components
M. G. Wyzgoski, C. H. M. Jacques
Polymers Department, General Motors Research Laboratories, Warren, Michigan 48090
ABSTRACT
The susceptibility of polycarbonate, polymethyl methacrylate, and cellulose acetate
butyrate to gasoline-induced stress cracking was evaluated by measuring the
critical strains of specimens exposed to a variety of commercial gasolines
and gasoline components. Cellulose acetate butyrate exhibited the greatest resistance
to gasoline followed by polymethyl methacrylate and polycarbonate. Stress
cracking was a complex function of gasoline composition. Measured critical
strains generally decreased and the severity of cracking of molded parts generally
increased as the total aromatic content of the gasolines increased. However,
a significant difference in critical strains was observed between the individual
aliphatic components of gasoline. No correlation was observed between
critical strain and gasoline type, i.e., premium, regular, or unleaded. The effect
of time of exposure was examined, and it was observed that for some binary
mixtures splashing caused much more severe crackin!
g than continuous exposure.

Mike,
I do not recall anyone admitting that they were using "cheap lawnmower
quality filter". It is difficult to influence someone to change to your way
of thinking, if you are going imply that they are already idiots. I assume
many on the List are very happy with the filters they are using and see no
need to change. I believe most pilots are optimistic about flying with the
equipment they have chosen to use, and so spreading doom and gloom about
using components that you do not favor will not win many, if any, over to
your way of thinking.
Please continue to float out your ideas, but leave off the doom and gloom,
and what you think may happen if others do not accept your personal choices.

Actually I made 2 boo boo's. I mean to say nose down not up.
Sometimes pitch sensitivity on landing could be the result of successive
stalls
which is not really a pitch problem but a pilot prob.
It's easy for a student or GA pilot to approach nose high because of the
great view
that gives the illusion of being the opposite.
But what do I know. I haven't even soloed yet

Vic, you clearly are doing your best to try to insert personal politics and bickering
into a important discussion where Herbs safety is at risk. You are doing
your best to distract from the facts and discussion at hand by posting something
that has ZERO information on Herbs problem, and does not contribute anything
to this thread except your personal agenda. Shame on you.
Herb has a dangerous condition that he is proposing of hiding through the use of
trim tabs instead of fixing. Herb did not pay attention to the good information
he got when told in a nice and gentle way. Given the second flight report
and the really bad " fixes " that Herb is proposing, Herb needed to be told
what a dangerous situation he has in a very direct manner. I don't care if it
hurts his feelings or not, Herb needed to hear it for his own good. I am not
trying to become best buddies with Herb or even care if he likes what I say or
not, but I did give him the best advice he could possibly get. Now if Herb
goes out and hurts himself, he will have no one but himself to blame as I did
everything humanly possible to warn him. So tell me Vic, since when is properly
rigging the wings of your Kolb to fly level and recheck the CG to make sure
it is in limits bad advice ? Do you have anything to add to this thread other
than trying to insert personal politics instead of facts into this discussion
?
I do see some really bad advice here in this thread, which was just given by you.
I know your type, a know nothing that tells others to only listen to people
he " Likes ". Let me get this straight, if Vic likes someone, everything they
say should be heeded, and if Vic does not like them, then they are not qualified
to talk about technical matters in aviation. This type of attitude may
work in Junior High school, but most people grow out of this " Clique " and "
gang " mentality ... This type of conduct definitely has no place in an aviation
forum where people get information that affect their and their passengers
safety. I cant think of a worse attitude to have towards aviation. Your advice
and attitude is a true disservice to this list, a person like you that puts
more importance on personal politics than on facts, knowledge, and good information
is the LAST type of person I would ever look to for advice or information
on airplanes.

Jack,
You are just wrong about dismissing my warning as gloom and doom. I have seen
these problems first hand at my field, and we have had FOUR reports recently here
on the list of similar problems. This is not gloom and doom, this is a very
REAL danger. This information will probably save someone out there a crash
one day. I don't care if some take offense to it or not, using some of these
cheap filters is just plain foolish, or stupid or whatever you want to call
it. If it hurts some feelings, so be it. What is important is that the smarter,
and more honest people will learn from this information and most probably
save someone a crash sooner or later.
John H,
If I am wrong about something in my previous posts about fuel filters, then by
all means speak up. I always stand behind the facts and sound advice, but I
have little patience for personal politics and peoples egos getting in the way
of good information and safety.

Don't learn to fast Thom, gasoline will cloud, crack lexan VERY quickly. I have
dripped non-ethanol gasoline on my lexan many times only to have to spend a
bunch of time polishing, not cleaning, but actually polishing out the horrible
milky while cloud it leaves behind. A couple weeks ago, I splashed non-ethanol
gasoline on my lexan side window, and within 20 seconds, there were hundreds
of small cracks in the lexan window, totally ruined it.
Just be thankful that for whatever reason you got lucky when you spilled your gas,
but that wont happen every time. Theory is one thing, but results trump theory
every time !

Vics " Advice " in the other thead was a poor attempt to insert personal politics

As usual with this type of know nothing person that puts personal politics ahead

A an cliquish type attitude that has no place in aviation, while the only
tidbit of information Vic gives about the pitch instability of Kolbs is totally

I think that making double sure the CG is correct is very important in
this situation.
On the other hand, don't forget that control sensitivity is relative.
The high lift-to-weight ratio of our light planes allows for a lot of
vertical motion that would have the sensation of pitch sensitivity,
especially if flying in breezy or theamally active conditions. Also our
planes react quickly to pitch control because the have relatively low
inertia in the pitch direction. These things would feel very
exaggerated to someone coming from GA experience.
When I first soloed in a single seat ultralight I was shocked at how
much more it blew around in the wind than the 2 seat version I trained
in (actually I was holding on for dear life). Then after flying
ultralights for years, when I learned to fly 4 seat GA aircraft it felt
like I was landing a school bus.

Mike Have No Fear and all;
The fuel filter clogging that Bro John H experienced, I was a passenger on
that flight.
It wouldn't have made any difference if the filter was your recommended
$80.00, plus shipping, plus taxes of all kinds, super duper filter that you
are pushing or a wash tub sized one, it would have clogged.
The cause was, we got the first load of fuel out of a brand new fuel system
that was built for refueling a/c at a Fly-in, in Texas. Undoubtedly the
system was never flushed out after assembly and we got the full load of
debris that was in the tank. Not water, debris. Trash, junk what ever you
want to call it.
Now, we will hear that John, should have checked the fuel source, maybe he
should have, but he didn't just like 99.99% of all pilots don't, to include
jet pilots :) under the same circumstances.
But Texas being such a fine state, they had laid out an 8,000 Ft concrete
runway for us to make our forced landing on, some 30 miles from where we
departed.
I think if most folks put their mind in gear before they put their fingers
on the keyboard, we could eliminate all of the P---ing contest with the
exception of those few that have that ego and hide behind the monitor
problem.

Mike,
With a FireFly, I have to fly light, and so I have been using one of those
little inexpensive paper filters. I placed it in the fuel line before the
pulse pump and connect it to the pump inlet with a clear see through hose.
The reason for doing this is that it ensures that the filter never sees any
high pressure, and if there is a leak in the filter or in the system ahead
of the filter, I will see bubbles in the tubing.
Some have said that you should stay away from paper filters as they will
seal off if water gets into the line. Think about this. If the filter is
put into the system in the dry condition and fuel is pumped up into the
filter, the fuel will wet the filter medium, and gasoline will pass on
through the filter. Later if water manages to be sucked up into the line,
the fuel wet filter medium will not let the water pass except and if it
becomes adsorbed by the ethanol in the fuel. If I placed the filter in the
lowest point in my fuel system, and if I did not periodically dry out my
tank, it could be possible to suck a sufficient amount of water into the
line and filter, so that, it could block filter fuel flow to the point that
it would starve the engine. But by placing the filter high and before the
pump this likely hood is almost non existent.
Using the system that I have described, I have never found any water in the
float bowl, and I have not experienced engine failure due to fuel
starvation. Each spring, I clean the tank.

Others have posted on the what, but not the why. Yes, billet is bar stock,
so the part is machined rather than being cast to the final (or nearly
final) shape. Parts machined from billet are [usually] stronger and more
accurate than an equivalent cast part. Also, many cast parts aren't the
same material; many casting alloys are inferior to the bar stock. Compare
cast iron to high strength steel, or aluminum or zinc (commonly called "pot

Here you can generally do aerobatics unless prohibited by the aircraft's
operating limitations. Most manufacturers nowadays issue a blanket
statement like "no acrobatic maneuvers permitted except the
following:...). For a homebuilt, the builder can specify (or not specify)
anything he likes and tests for during the flight test phase. Of course
there are other restrictions like minimum altitudes, no acro over congested
areas or on airways, parachutes must be worn unless flying solo, etc.

Rick, that applies to aircraft certificated as LSA. For

If you have a "strong" roll force, you should be checking the airplane's
rig. Trim tabs are for light forces. As to whether you need rudder or
aileron trim, it's whatever it takes to make the airplane fly level with
the ball (or yaw string) centered.

Are you sure your weight and balance is OK? A tailheavy aircraft will be

Brother Jim,
Your account adds a lot of information to this engine failure, from what you report
no fuel filter would have prevented the engine failure. This is why I was
very careful to say, Maybe and Possibly when referring to his engine failure.
What is a certainty is that more area in a filter element is better, and
is less likely to clog and result in an engine failure. My Honda Civic has a
filter with 10 times more filter area than the little filters many are using
in their planes, its just good design.
As far as John H's filter, it has obviously worked well for him for 14 years, John
H is a very smart man and knows how to keep alive in a Kolb in conditions
most of us will ever see. John H is the first guy I go to when I have a Kolb
question. I am not trying to get John H to change a filter that has served him
well for so long.
But here is my question, given that all brands seem to be importing the same model
filter from China, but now made cheaply and very prone to failure, how can
anyone tell guys that recently bought or are planning on buying this model of
filter that they are safe to use in an airplane. Look at Gary Siegrest's report

| Subject: | Re: Fuel Filter Failure |
Hey All, I am using a Kawasaki Jetski, water separator fuel filter on an old Ultrastar
that I am rebuilding. Got it off Ebay. It looks like a gascolator with
aluminum top and plastic setteling bowl. Inside it has about an 1' diameter x
1 1/2" long stainless mess filter. Bowl has a spring under filter to keep it
off bottom and a o'ring to seal filter to inlet. Then you have about 1" or better
of bowl to collect water. You unscrew ring retainer to remove bowl to service
the cleanable filter mesh or to dump trapped water. This is the best thing
I have found for filtering and water removal and you don't have to spend a bunch
to service it. Also weighs about 6 or 8ozs. My three cents. CT.

But here is my question, given that all brands seem to be importing
the same model filter from China, but now made cheaply and very prone to
failure, how can anyone tell guys that recently bought or are planning
on buying this model of filter that they are safe to use in an airplane.
Look at Gary Siegrest's report that was posted today. I cant
overemphasize how dangerous a floor full of gasoline is in flight. I
previously talked about this exact type of problem with these filters,
it is well known, and there have been many previous reports of this
model fuel filter failing in the same way.
What everyone reading this list needs to know is, given the reality of
cheap Chinese imports of almost every product, what filter should people
buy for their Kolb today ?

Mike, I think what every one is trying to say is, that no one cares
one way or another what you believe or how strongly you might believe
it. Not a problem, It is your choice. No one will tell you that it is a
bad choice. What most have trouble with is that you don't seem to want
to let anyone else believe any thing different. We all make choices,
some good, some bad. Sometimes that is the only thing that keeps humans
from over running the world. You just have to face it, not every one
sees the same thing the same way you do. All anyone of us can do is make
recommendations, if they choose to ignore that and take a different
path, so be it.

Carl, does it look like this? :

If so it looks like a decent piece of work. How's the element
replacement availability?
Today I was in Walmart and bought a Fram G12 fuel filter. Clear
bowl, captive element
and 1/4" nipples. Made in Israel.
I might try it next year.

I've heard both (that it's OK and that it's not OK). Even the chemical
compatibility charts differ on whether it's OK. A few months ago I decided
to make my own fuel strainer, and wanting a clear bowl, I made it out of
polycarbonate (supplier unknown; it was a block I scrounged at work):
<http://smg.photobucket.com/albums/v486/flyparafan/Kolb/?action=view¤t=gascolator.jpg>
I left it full of gas/oil mix (auto gas with 10% ethanol) for a week, no
change... then mounted it on my plane, where it's performed fine ever since.
It has two inlets (one for each tank), a quick drain, and a coarse
stainless screen in the outlet feeding the main inline filter (the glass
tube kind).

Mike;
I don't believe that John ever said for anyone to buy the type filter he has
used. he said it has worked for him.
There is a big difference.

| Subject: | Re: First Flight follow-up, |
I bought a Firestar II.
I called Travis at Kolb and asked how I should go about learning to fly one.
First idea, come to Kolb and we can teach you in one of ours.
Second idea, Find an instructor with a Challenger II, they fly similar.
I took the second. My instructor told me a lot of GA guys are caught off guard
by these little planes and have problems.
After I flew the Challenger I went and flew an Aeronca.
I damn near flew that into the ground, it works different than a Challenger, slower
to respond to pitch commands on landing.
The first thing I did to my Firestar was drag the right wingtip down the tarmac
and almost ground loop it.
Things are better now.
Good luck, hope things get better, I had to get that piece to adjust my wings.
My plane is not as stable as my instructors Challenger, his plane is not as responsive
as mine.
