This has always been my habit (similar markings also to the oilfilter &
base as well). Just do it simple by red permanent marker. I have never
seen any movements between the rim and tire/tyre. So that is not the
reason for once-a-year-flat-tyre-syndrom in my case.

I remember once listening to a presentation by a professional engineer
and pilot at an EAA meeting.
He pointed out that it is very important to make a permanent mark on the
rim(s) and on the tire after tube installation. And this should be
checked as part of every preflight inspection. Apparently this slippage
is quite common, regardless of aircraft type, when landing on hard
runways.

Hi All,
Jim's comments prompted my to share some additional thoughts. I found that
my new tyre "stood taller" than the one I replaced. My theory is that the
old tyre was run at low pressures so long that the side walls lost their
strength. I think the design pressure for this tyre is something like 35
psi.
The other comment was that I did loose one inner tube to slippage, and two
tubes to side wall wear so I increased my running pressure to around 22 ~ 24
psi. I used to have a maker on the side, but I forgot to put in on this
time so thanks for the reminder.
I do have a question to the forum. is is possible to seal the split rim and
turn it into a tube less configuration ?

All,
I think the side wall wearing is the point and that will be high-lighted
when a low pressure, not a quality tube, ageing, bad manners when
installing and a wrong tube size.

Jim and all
The problem is to find and get high quality tubes. There are many
top-of-the-line tube brands like Michelin or Good Year but they do not
have types with a valve stem bent to 90 degrees. They say tubes with 90
degree valves are only for light aircrafts and their owners do not pay
for quality. They claim they buy only low prices and offers...
However, brand name Leakguard by Dresser promised to make size 7.00x6
with a valve stem 90 degrees as a special order.
We do not have Leakguard model because the 90 degree is for Light Sport
Aircraft.
I can have special order these in Aircraft Grade, Leakguard with 100
pcs. minimum at $42.95 each on 100 pcs. order. Delivery 60 days.
Maybe you can get the owners together to buy 100?

Hi Jim,
have you any idea what is your tube brand name? I think that (the tube)
could be something between happy landing and a possible disaster or pain
at least.
***
To prevent future tube-related accidents my plan is to go as follows:
1) change a very best available tube (www.desser.com , McCreary ?)
2) change it for new one regularly ie. once a year to prevent it is
ageing.
3) consider seriously what is the best size for it (must be same as tyre
and that is in my case 7.00-6)
4) install it with extreme care and baby bottom talcum
5) keep a good tyre pressure ie. 2,0 =93 2,2 bar
6) fill the tyre with some well known pre puncture liquid (www.slime.com
?)
7) have a low tube pressure on-flight control system (www.conrad.fr
,thanks Alain)
8) carry always in a plane a spare tube (with a lifting block)

Dear Jim
Read careful my post: I like to use pressure 2,0 - 2,2 bars. 2,1 bar =
30,45 PSI. So we land with same pressures. Pressure - low or high - is
not a reason.
What is your tube brand name?
What is your tube and tyre size?
Until I will get a reason and solution I am going to do same as Paul is
doing: changeing regularly tube. Makes me sense to change it every year
(= in my case every 50 hrs /about 50 - 100 landings. I never can do it
in 30 minutes but so what. Tube is very cheap. For example yeasterday I
spent 6 hrs fighting with that problem with my wife and that
newspaperman. That is 18 hrs + all the extra fees + 400 km driving car.
That must be same as buying let us say 100 pcs of tubes.
BTW also I use masses of baby bottom talcum. That delicate scent is a
bit embarrassing...

All monowheel drivers
Following this thread today... I have a few commits to throw to the
forum...I notice that Europa requires very low tire pressure in their
manual....
I also noticed today that quiet a few monowheel drivers are having
flat's....I suspect that with the low air pressure, when you land the
sidewals are flexing due to low air pressure...this is probably
"pinching the inner tube" and then the tire goes flat....
I have always kept 32 PSI in the tire. IN 10 years, and two tires and
tubes, I have never had a flat....Yes I know I have been blessed by the
good luck god..
Thank about it with 32 P S In the tube the sidewalls are not
flexing......Just my thought's on this matter....

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:

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.

I have Argon at the hanger (for my TIG welder). Would that work in the
place of Nitrogen ?

It is near Nitrogen (both a inert =9Cslow=9D type gases and
used as a protective gas when welding, not harmful, not flammable and
their weight is about similar. In air there is 78% of Nitrogen anyway
but only 0,94% of Argon.
Remember: the main purpose is to get all the Oxygen out!
I assume Argon is much more expensive than Nitrogen.
But if you have it, why not try it and report us.
Make a sign to your gear leg: =9CPure Argon filled tyre=9D
=93 what a respect you will get!

I can recommend a Brompton from the uk(two wheels mind) as I have used one in
my C42 for several years. I think its still the smallest,lightest and best to
ride any distance on.

| Subject: | first fuel in tank has gone brown |
Curious, I filled my tank for the first time to full. The tank must be 7 years
old or more. I pumped all but 15 lts out and over a few weeks the remainer seems
to be going brown ish. I presume its a reaction with polythene, any clues?
is it normal?

Jeff,
I'd recommend Europa to be sure you get the right stuff. Check with Bud Yerly
( budyerly@msn.com or 813-653-4989) at Custom Flight Creations. He may have some
in stock.
If not, the pins are available in the US from sources like McMasater-Carr. Be
sure you get the right size, material and strength. There's also a manufacturer
over in Fort Worth but my main computer is down so I can't get the information
from them right now. I'll pass along that information when my computer is
back up and running.

Hi Bud-
We are in NC on our way to Oshkosh.=C2- I didn't figure you would go.=C2
- I know it is busy in the shop and it is also a very expensive propositi
on.=C2- If anyone there wants to order a kit, I'll get a deposit and get
the information to you.=C2- I don't think Europa has ever gone for a disp
lay at Oshkosh; I think SNF has been about it.=C2-
Keep in touch!=C2- Will e-mail you all of the orders from there.
Jim
