Glad to hear you and your airplane came out ok.
Makes me wonder if anyone ever had a flat tire with an Europa tri-gear?
What is then the sensation?
I guess if it is the nose wheel it is not a big thing with proper
landing habits. By the time it is loaded with weight the speed should
already be very low.
But what if it is one of the main gears? I guess it will take very hard
braking on the opposite wheel to prevent a very violent ground loop (if
at all it will be possible to brake hard enough).
Any experiences, opinions?
Frans

Subject: 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.

Flat tires in a tri gear do not appear to be a big deal.
I have had three in seven years of flying.
Two were nosewheel flats due to pinched inner tubes on the outer,
not inner surface of the tube with slow breakdown of integrity.
These flats occurred while taxiing. One of those occurred at
night at KISP at the far end of Rwy 24, about 1.5 nm from starting ramp.
Of note, my call to the tower elicited an EMS vehicle (ambulance!), not
a tow rig which then took an extra hour to organize.
The other nose gear flat occurred after only 0.5 sm of taxiing.
The main gear flat occurred on landing and the a/c remained controllable
with rudder and brakes. It was a rapid leak, not a sudden blowout.

Riamo,
Thanks for your interesting description of the event.... It's always
important to share experiences and yours was fascinating to read.
However, could you be more descriptive of the Jacking Block you
always carry? Perhaps I missed it in your earlier messages. I'm sure we
need to follow your example if it saves a great deal of trouble.
Thanks,
Ferg

Hi Lucio
why not? And also girlfriends, flying mothers and mothers in law,
daughters and do not forget all those mistresses.
Without my wife OH-XRT would have never been completed. Without her
neverending support I would have stopped flying. When building we got
married. So, she is vital and very virile part of my Europa life.
The Plan is to join Europa Mile High Club
(after autopilot installation and some practise that should be
performable happily and safely. That would be also very romantic because
I have there zillions of dimmable red lights and also slow bedroom music
via Bluetooth from B&O=C2=B4s MP3.
Just wonder who will be the very first Europa child who has been
manufactured in the (flying) Europa. Some of you may think that is
impossible because CofG but that is well solveable. My wife is behind my
shoulder and will press delete quite soon so I have to move on...
How many female Europa pilots there are? How many of you have a lady
=93 wife or not =93 who want to fly with you? Maybe some of
you have many of them? How many then (You all remember my personal
record is to fly Europa with three ladies omboard). Would you like to
share your =9CLady in Europa=9D photos? Maybe this a a place
for some kind competition?
I know couple of them like Frans Veldman=C2=B4s charming wife Ilona.
Also Stefan Ingemarson=C2=B4s flying lady and Dirk Oyen=C2=B4s Chantal
are magnificent. Maybe that is something to do with Europas!
BTW My wife Marke wants me to teach her to fly Europa unofficially. Just
for fun and just in case, you know. Our goal is she could make a safe
landing during this year. I mean a safe Mono landing...with some air in
the tube please. That air should be between ground and a center axle.
***
Thanks for a Slime tip =93 I will check it out immediately.

Hi Mike
I run a bit overpressurized (not me but my tire). That is from 2,0 to
2,2 bars. I hate a soft tire =93 it is like a waterfilled air
balloon and I as a child jumping on it.
BTW: I do not use gauge for checking an air pressure. I use a ruler
which is exatly 162 mm (6,38 inches) long. That is a distance from the
hard surface to the under surface of the center axle opposite brake disc
side.
- no batteries
- no calibration
- unbreakable
- very light
- very cheap
- very strong
- no one want to steal it
- easy to make a new one
OK =93 I know. It does not take care of a tire loosing rubber
material during the years but that is really insignificant. One
millimeter eq. about 0,01 bars. OAT means more. 162 mm is a good gap for
me at least!
***
I try to find a way to get a pressure info during flight. I assume there
could be findable batteryoperated wireless radio-operated pressure
senders which could locate in the valve top. Have you seen such an
items?
I wanna get a pressure info during the flight before landing and also to
know low pressure to land before no pressure at all.
That could make my day =93 I really wish yesterday was the last
incident like this.
I cannot be so lucky forever.
Modern cars do check the pressure by checking the rotateing speed of the
wheels but our tires are not rotateing when flying...

You were right but absolutely alcohol free. That is a principle for me.
But later at home, I think I got some real amber nectars. At least my

Hi All,
I have found that the inner tubes on my mono to be an ongoing problem and I
now routinely change my inner tube every 150 hours as preventative
maintenance. The tubes I have been using are not very expensive and I think
that they are from China. Recently Bud made me aware that there is a
certified inner tube available at about 3 times the cost and if they last
longer then they would be so worth it!
I do recall when I mentioned on the forum that I was losing inner tubes
regularly that some people were surprised and that they had not had a
problem so perhaps this can be accounted for by different inner tubes being
available. The failure I get is that the side wall of the inner tube get
small splits in it due to chafing. I typically run my tire at about 24 psi,
which is higher than the recommended by Europa. BTW I do use talcum powder
when I install the inner tube.
I have had 3 blow outs on a hard surface and fortunately I was able to keep
directional control. The challenge I found is that with a flat tire the
mono is nearly impossible to move. It happen to me at a large airport once
which got the airport authority excited because they had to shut the runway
down and divert all of the 737's to a shorter runway. I now carry a jacking
block, tools and a spare inner tube with me and I can now do the change out
in less than 30 minutes.
Next time around I am going to try a certified inner tube in the hope that
it will last longer.

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 Jim,
We have over 800 hours on our monowheel without any flats as well, but we run 18-19
psi, as recommended. We fly almost exclusively on pavement, which I would
expect to be harder on tires and tubes than grass.
Regards,
Terry

I keep the tyre pressure between 28-30 psi. No problems with the tyre after 250hours
464 cycles. Only disadvantage with the higher pressure is one has to be
more diligent on controlling the aircraft path when landing on hard pavement runways.
I did not use the original Europa tyre but use the Mccready? Air tire,
narrower and stronger.

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....

I keep the tyre pressure between 28-30 psi. No
problems with the tyre after 250hours 464 cycles.
Only disadvantage with the higher pressure is one
has to be more diligent on controlling the
aircraft path when landing on hard pavement
runways. I did not use the original Europa tyre
but use the Mccready? Air tire, narrower and
stronger.

Riamo -Hello Ferg
Look at the photos =93 I am sure you get the idea for a simple
wooden block =93 a real mind saveing angel. With lightening holes
it is very light but still strong. Notice high quality bolts (2 x) which
will carry all the load when jacking up.
You will get all the dimensions from your gear including the angle of
the triangle shape.
Let me know if you need more info or LHAD drawings *.

Riamo,
Thanks for your interesting description of the event....
It=99s always important to share experiences and yours was
fascinating to read.
However, could you be more descriptive of the Jacking Block you
always carry? Perhaps I missed it in your earlier messages. I=99m
sure we need to follow your example if it saves a great deal of trouble.
Thanks,

Hi Lucio
why not? And also girlfriends, flying mothers and mothers in law,
daughters and do not forget all those mistresses.
Without my wife OH-XRT would have never been completed. Without her
neverending support I would have stopped flying. When building we got
married. So, she is vital and very virile part of my Europa life.
The Plan is to join Europa Mile High Club
(after autopilot installation and some practise that should be
performable happily and safely. That would be also very romantic because
I have there zillions of dimmable red lights and also slow bedroom music
via Bluetooth from B&O=C2=B4s MP3.
Just wonder who will be the very first Europa child who has been
manufactured in the (flying) Europa. Some of you may think that is
impossible because CofG but that is well solveable. My wife is behind my
shoulder and will press delete quite soon so I have to move on...
How many female Europa pilots there are? How many of you have a lady
=93 wife or not =93 who want to fly with you? Maybe some of
you have many of them? How many then (You all remember my personal
record is to fly Europa with three ladies omboard). Would you like to
share your =9CLady in Europa=9D photos? Maybe this a a place
for some kind competition?
I know couple of them like Frans Veldman=C2=B4s charming wife Ilona.
Also Stefan Ingemarson=C2=B4s flying lady and Dirk Oyen=C2=B4s Chantal
are magnificent. Maybe that is something to do with Europas!
BTW My wife Marke wants me to teach her to fly Europa unofficially. Just
for fun and just in case, you know. Our goal is she could make a safe
landing during this year. I mean a safe Mono landing...with some air in
the tube please. That air should be between ground and a center axle.

Thanks for a Slime tip =93 I will check it out immediately.

Subject: 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.

Not sure what the size was. Next time I go out to the aircraft I will have a look.

Graham,
Yes, I think that is why Kim Prout recommended the narrower McCreary tire an
d higher pressure
when I flew with him many years ago now.
