I had hoped to organise a Last of the Summer Wine trip in mid to late
September - which basically consists of flying very gently round some of the
nicer parts of France concentrating on enjoyment! Unfortunately my
commitments now make it impossible for me to do that and I would be
delighted to hear from anyone who might be prepared to take on that not very
onerous responsibility. Maybe one our French friends could be persuaded to
show us the parts we might not have yet discovered? It would clearly need to
miss the LAA Rally weekend, 2-4/9/11 and the Texel weekend, 9-11/9/11

| Subject: | Re: Tire /tyre landing incident /accident |
Raimo,
Sorry for the slow response.
Alas no tube is perfect and frankly, I hate how the bent tube wheel
works. The stem never sets really straight, even when I affix a 5/16
inch by 32 nut and a washer to help it out.
I have often wondered myself why not put some pre-puncture fluid in a
tube and fill with an inert gas. Or even fill the darned thing with the
fix a flat type fluid. Now that we have the electronic tire pressure
monitoring devices that work in tubeless tires, can it be worked out on
a tubed tire? Ah to have the time to research and develop new things.
With very inexpensive and light air compressors available now, we could
have our own built in auto tire inflation system like the big guys. I
am seriously considering adding a compressor to my plane powered direct
from the battery with a valve stem sticking out of the fuselage bottom.
When I get to the plane and need some air, I pull out my very light
filler tube out of the baggage bay and hook up. With my very easy to
open wheel pants, I wouldn't need to wait for the Fixed Based Operators
mechanic or have to drag out my gear to fill the always occurring low
tire. Three screws, open the pant and fill the tire.
As you already know, my main concern with the larger tire of 7 or 8
inches, the side wall will tend to fail if it loses pressure. Once the
side wall fails, the tube can't fix that problem so the tire will fail.
As for the 6 inch tube, that is quite a stretch for this sized tube as
there is a huge difference between 6 and 7 inch tires, and in the event
of a puncture I had the thought it may be more of a blow out rather than
a floppy tire roll out.
Also if you go to an 8 ply sidewall, what will that do to the tires
ability to absorb the shock.
I supposed if we all made perfect landings on dead smooth wide fields we
wouldn't have a concern with a stiffer tire....
Regards,
Bud

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<http://www.11d.nl/>

Check also www.purinvent.com<http://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.

Subject: Re: Europa-List: Tire /tyre landing incident /accident
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.

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.

Subject: Re: Europa-List: Tire /tyre landing incident /accident
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.
