Flyers.
Hi! All
I can advise you that in spite of the weather this year's successful event,
having paid for numerous Aerobatic Performers etc, will make a considerable
donation to the Lincolnshire Air Ambulance Charity. Many thanks to those who
contributed by attending the event. Your presence was deeply appreciated.
I am now able to declare dates for the same event in 2012 as June 16th and
17th . Hopefully many more "South of Watford" and in Europe beyond will put
the NEW dates in their diaries and strive to show up for this exciting
event.
Hopefully the Europa Club Mag. Editor and the LAA magazine Editors will
"bag" this information and publish it in good time to help erase any
possibility of dates clashing elsewhere.?
Best regards
Bob Harrison G-PTAG

Dear Bud specially and all of you
My tube installation has been perfect you can be sure about it.
Remember, many of us have had tube problems like Paul MacAllister for
instance. I am sure he is a well known pro. Never grease the wheel trim!
I have markings no movements between the trim and tire /tyre.
Sorry but those companies which make for example tubes for planes they
have no a real liability. Just a morals or nothing. There is no place I
can send an invoice !
My principle: I am not flying for saveing money! I do understand in most
cases paying more = get more safety. I would love to pay 1000 $ for a
tube which is *really* unbreakable !!!
***
I purchased and got today a tyre pre-puncture liquid from Netherlands. I
have it 25 liter = about 6 gallons and I need it only 0,25 liters. So
I haveso far free tyre puncture liquids for about 99 Europas who ever
will land to EFTP!
Price: 550 euros /canister. As I wrote I am not saveing when it is the
question of my or my family=C2=B4s (flight) safety.
Check www.11d.nl
***
Check also www.purinvent.com
Very interesting =93 that is practically unbreakable tyre /tire
solution.

Rob Robson, US Sales manager of GA Goodyear answered me as follows
below.
The big question: how do you think is the type G15/6.00-6 tube for the
tire /tyre 7.00-6 ?
If you think it is ok that will be my way to go on. No matter about the
costs!
An idea 2 is (IMHO) not so good (to bed the valve).
Raimo Toivio OH-XRT Finland (yber alles)
Hi Raimo,
We make a tube that is sized 7.00/8.00-6 which will fit in a 7.00-6
tire, but it has a TR-20 straight valve. We do not make one that has a
bent 90-degree valve.
I think that you have two options if you would like to use Goodyear
tubes:
1. Try a G15/6.00-6 tube with a TR-67 valve (which is a bent 90-deg
valve). The 7.00-6 tire is roughly 1 1/4" taller and 3/4" wider than a
6.00-6 tire, so the tube will most likely stretch to fit.
2. Try bending the valve on a 7.00/8.00-6 tube to fit your wheel.
I don't know which option would work better; it depends primarily on the
wheel and where the valve hole is.

Raimo,
Yes, McCreary has probably been bought out, but they still have a phone
number and are listed in Aircraft Spruce as a supplier. The adds still
say:
"Located in Indiana, PA and Unicoi, TN, Specialty Tires is committed to
producing high quality tires that are 100% Made in America."
I have had good luck with the Europa tubes which are bought through
aircraft supply houses, however, I had good luck with the Asian made
tractor tubes that were original in the mono kit too. As I said in a
past post, installation has much to do with a tubes longevity. I know
that if you grease the wheel rim, the tire can spin on the wheel and the
tube doesn't last long at all, nor does the tire or wheel pant. Ah the
exuberance of youth and the desire to get in the air quick.
You are probably right that many tubes (and tires now days) are made
overseas, maybe even by the same company that makes lawn tractor tires,
but when you put the use on a tire or tube that says "airplane" you pay
more, supposedly for the quality and or inspection standards but mostly
for liability I'm sure. Let's face it, your $600 alternator on a Piper
can be bought with the same part number at an auto parts store for $60.
But the auto parts store one doesn't say airplane.
Everything on my plane comes from an airplane manufacturer or supplier.
Why risk a $100,000 investment on a $12 part.
Regards,
Bud

Hi Bud
and thanks for a nice comment.
However
Replacement Tubes: Europa tubes are now made by McCreary and are for
a 7-8 inch tire. They are very well built, and have the exact 90 degree
bend and placement of the valve stem for the mono's wheel. They are
about $130 each, and again worth every penny. It is my experience they
are changed only on puncture not wear.
Are you sure they are McCreary=C2=B4s? On Europas sites they say only
=9CTube =93 Mono =93 suits 7.00 and 8.00 tyres main
tube =93 tba=9D.
In fact there is not anymore a company named Mc Creary. Today it is
known to be Specialty Tires of America, formerly known as McCreary Tire.
I assume those McCreary /Specialty Tires of America tubes are made in
Indonesian by Deli.
American Racer Tires and its sister company Specialty Tires of America
were originally known as the McCreary Tire & Rubber Company, founded in
1915 in Indiana, Pennsylvania.
***
Watch this:
Hi Raimo.
We have good quality, but Asian manufacture $21.95 each
We have good luck with these.
Hi Steven
What is the brand name of Asian manufacture? Is it maybe a Deli from
Indonesian?
Wishes, Raimo
Correct. Deli Indonesia
Best regards
Steve
I have had four incidents in four years with Deli. That means a case
after every 50 flight hours /70 landings. You bet I will not have a Deli
any more...
Terveisin, Raimo
***
So...no Deli any more.
***
I have asked Good Year=C2=B4s US General Aviation Sales Manager Robert
Robson to find us the best available tube for Monowheelers. I will let
you know the results.
As you maybe notice, this is a serious business for me.

To all, and congrats to Raimo Toivio
When preparation, proficiency and proper procedures meet a potentially
catastrophic chain of events, the chain is broken and the aircraft,
pilot and passengers all have a story to tell rather than being an
accident statistic.
Your thorough planning for tire changes in the field, spares, and most
importantly a lovely and supportive wife makes the event a nuisance tire
change out in the field, so I am hoping you bought your wife a great
dinner and told her how much you appreciate her.
As for tires and tubes, from what I can report from the US mono pilots
that have shared their experiences with me here goes:
Original Classic Equipment was an industrial 8 inch tire and tube.
Cheap, strong but rather thin with squishy sides. The clearances were
minimal from the frame and cockpit module and during landing the brake
caliper on a flat tire tore it up pretty quick. About 2000 most guys
started going with the 7 inch McCreary as a replacement around here. It
is narrower and of course a little lower. The original tube was a bit
thin but cheap at $35 for a lawn tire tube.
Replacement Tires:
The McCreary 7 inch six ply seems to work very well with very long
life. This tire has more clearance from the frame, the wheel well, and
its six ply sides is very stiff. It is available through Europa or
Aircraft Spruce (PN 06-09600):
for about $130 US and is worth every penny.
Replacement Tubes: Europa tubes are now made by McCreary and are for
a 7-8 inch tire. They are very well built, and have the exact 90 degree
bend and placement of the valve stem for the mono's wheel. They are
about $130 each, and again worth every penny. It is my experience they
are changed only on puncture not wear.
Most taxi failures need a serious autopsy of the tube. I have found
with new clients that they pinch the tube or cut the stem. Once the
tire goes flat, it gets cut by the brake caliper. We have gone to a
full proof method here in the shop. First we inspect the wheel for any
burrs or sharp edges on the rim and especially on the valve stem. We
smooth these out if present. Then thoroughly clean and dry the wheel.
We cut card stock that fits the recess machined into the wheel and glue
it in place with super glue dabs on one side only. Then show the client
how the wheels go together and to watch for the white paper in the wheel
half split with an inspection mirror to make sure all goes together
easily. Then the tube is lightly powdered , inserted into the tire,
aligned with the stem aligned with the dot (not always present) and
slide the wheel into the tire. Carefully align the tube stem and ensure
the tube is not twisted. Now carefully install the other wheel half and
gently push the two halves together. Insert bolts and pull up evenly.
The tire is ready to inflate.
A suitable lubricant for tire to wheel during installation is not axel
grease according to the FAA maintenance folks. There is no reason for
lube on a well maintained rim free of dirt, corrosion etc. If the tire
will not go on the rim, use a proper lube such as Freylube or a mixture
of dish soap and water with no more than 10% mineral oil. Allow the
solution to dry before putting the tire in use. Petroleum lubricants
between the tire and rim may cause the tire to rotate on hard braking or
run-up (and the tire will rotate on the rim with a 914 at full blast
with an Airmaster Prop), causing tube stem or tube failure. Learn from
my mistake. Read Michelin's guide to tire installation:

Subject: Europa-List: Tire /tyre landing incident /accident
Dear All,
it is a long time since I have been here. Today it happened
something and I got an Europa Energy Burst (aka ENB) to write on the
list. I think this could be useful info for most of you Europa (or any
GA plane) operators. Let me tell you what was it and how it went:
***
I have worked couple of years to make an Europa story to the largest
All and Universal Technical Scandinavian Magazine which is published in
the Scandinavian countries. I have had several flying experiences with
their very speciall aviation editor. Today we decided to fly to one very
remote airfield. Everything went as normally.
Please notice I have a Monowheel, The Most Sexy GA ever built.
***
Just after a touchdown I
- smelled a well burned rubber and then after
- noticed immediately a strong autobrakeing
- noticed immeadiately the position of the aircraft is not normal
(too low and too leveled)
- noticed a rumbling noise
- noticed it is not *very* well steerable or att all and so we went
out of the runway to the port side of the grass area
We went out of the runway. That concrete runway 33 was quite narrow,
just 6 metres or about 20 feets only. I understood at once what was the
name of the game. During first seconds I was wondering if it (tha plane)
will be inverted. The brakeing effect was so hard. After seconds I was
wondering if I will lose only my prop (and engine) at least. It took
only seconds. We stopped and I ask the editor how about if I will now
switch off the fuel pump, electrics, engine, are you ok and how do you
feel now?
What a story for a newspaperman!
The landing was very normal before the touch down. Let me say, I had
completed 416 pcs of an Europa Monowheel landings and this was better
than 8 (0-10) just before touch down . I (we) assume the tire/tyre was
empty before landing. Not a big bang when landing at all, no no.
***
During the years we (Europa Operators) have speculated what will
happen when landing a mono with an empty tire /tyre. Now I /we know: If
lucky nothing! My prop was still a virgin (configuration: Warp Drive
blades with a wonderful Airmaster hub from NZ). The soil out of the
runway was quite soft. There was still a clearance between the mother
ground and the blades about 50 mm /2 inches. I kept the stick hard back
during the landing. Some of you may remember I do love high speed
landings like on final 70 knots and during a touch down around 60 knots.
The brakeing effect was very strong because of an empty main (and only!)
tire /tyre: it took only less than 100 metres /300 feets from touch down
point to the final stop. Zero winds. Runway is a bit upphill.
***
After I checked I am ok and my co-pilot was also ok and my plane was
about ok I called bureacrats as they call to do in Finland immediately.
The Police came and people from The Air Accident Investigators called
me. That was an Finnish Army Airbase also. They came and tried to help
us by giving some air to my empty wheel but do not succeeded because the
inner tube was totally destroyed during the landing (just 300 metres
from us they =93 Finnish Army - were launching unmannned planes by
steam catapult).
***
I called my loving (and sooo beautiful) wife and she took
immediately the spare inner tube with her from our hangar and was
heading by car with a trailer 200 km /125 miles to us. Without a special
jacking block which I always carry with me it would have been impossible
task to lift the Mono upp and take the wheel out and change an inner
tube for a new one. All together it took 6 hours until we were flyable
again. Let me say The Editor still wanted to fly with me back to EFTP.
We completed some touches and goes to check would it be again empty or
not. It was not. What a smile.
Attached a pic =9Can accident place, my plane, my Wife and Mr
Editor doing tire /tyre changeing jobs=9D.
***
Fuck!
I have operatored my Europa 4 seasons and this was my 4th case of an
empty and a broken main wheel! This was a first experience during a
landing. All the other cases have been during taxiing or so. Why?! I
have an original size and a brand of an inner tube which is 8.00
=93 7(6) which means it is ok for a size 7 and 6. They say so. I
had two years an original outer tyre /tire which was like from a colf
car but after earlier incidents I changed it for a real aircraft tyre
/tire (brand name Air Trac). Always the hole has been in the side of the
inner tyre. It has always been let me say about 10 mm /0,4 inches) long
crack.
I (I point *I*) assume that is the question of the bad quality of
the Deli (made in Indonesian) innner tyres.
***
Let me and we all know the source for the high quality inner tubes
please!
Let me and all know is there any clever stuff to put inside of the
inner tube *before* accident to prevent this kinds of accidents.
We all know there are stuffs to put inside the inner tubes to make
our day *after* it is empty. That is not a solution and nothing to do
with a catastrophic failure when the crack is 10 mm or wider.
I /we need a possibility to prevent this kind of (very stupid)
not-so-purpose-to-happend-accidents.
***
Monowheels pilots =93 please do not ever fly far away w/o a
lifting block. That is a sensation.
Thanks for Mr. Dirk van Oyen from Belgium (first time in use a day
after a Maiden Flight =93 that was 30.04.2007).
***
Thanks for this wonderful chance to share and make my day.
I have many topics to talk with you. Many questions to answer. Many
things to do since the end of the last summer. I will come back.
Thanks you are there. All of you.

Specially Mr Kingsley from Oz and Mr Fred Klein from US.
I am happy you are there.

Just a few thoughts:
1) It is available in 1/4 liters bottles as well, so you could have
saved quite some money.
2) According to the website it is only for punctures in the thread, not
in the sidewalls. But if I remember correctly the sidewalls is where the
monowheels usually develop the leaks.
3) According to the website it is for slow moving vehicles only. But I
wouldn't exactly describe an Europa as a slow moving vehicle.
4) They also say that it can be washed away with water if you want to
repair the tire. I'm not sure what to think about this: Does it also
mean that when you fly through the rain the stuff dissolves? You might
not even know that you had a leak previously but suddenly the tire
empties and you are in for a surprise when you land on the wet runway.
5) The stuff remains liquid inside the tire. During landing the wheel
accelerates in a very short time when the wheel makes initial contact
with the runway. The liquid stuff inside the tire has inertia and I'm
not sure what the effect will be. For sure it will have a lot of
friction for a short moment, and it may give a massive imbalance when it
has piled up on the bottom of the tire during flight and suddenly has to
rotate very fast, just like a washing machine that starts to hop when
the laundry piled up on one side. You might be the inventor of the
"self-bouncing monowheel". This imbalance may be the reason why it is
described as "for slow moving vehicles only".
So, be careful here! You might want to add the stuff in stages and test
each stage with an actual landing to see how it behaves.
Also, what is the effect of temperature on that liquid stuff? Will it
become a jelly like lump inside the tire if it gets too cold? Maybe put
it overnight in a freezer and see what becomes of it.

I fully agree but you should make sure you are not trading one risk for
another. If this stuff really works one would expect that it would be
used already widely in the airplane industry.

Steve, Herewith. It looks as though (weather willing) we shall be 4 planes,
so I intend to meet up there and then see what folk prefer to do, like cycle
all to Le T; Cycle all to the great sea food restaurant at Etaples; do their
own thing.
