| Subject: | Mod 72 question & order |
Hi Roger,
It's been a while since we last chatted. I hope E04 is doing well with
new orders these days. Thanks very much for chiming in with further
detail and advice.
As my frame is not yet installed in my build I have a couple of
questions:
1- Is E04 considering redesigning the frame design to eliminate the need
for the offset weld brackets? (thus including a matching intermediate
frame)?
2- How are new frames from the factory designed? With longer offset tabs
which have longer welds (welded further back along the upper tubes) to
reduce the bending forces, and with thicker walled upper tubes?
3- Are the new frame's welds properly annealed to reduce brittleness?
4- **Were the old frames annealed (as far as you are aware)?
5- How much would a new (redesigned) frame be?
6- since my frame is not yet installed, Could I request a pair of
mod-inserts which are the entire length of the upper tubes (to provide a
more secure mounting with the tunnel/frame mounting bolts)? And how much
would these longer inserts cost?
As I've already ordered some stage-1 related parts from E04 (parts
shorted to me by the previous 'owner' of Europa), you already have my
Credit Card information. My shipping address is:
Peter Zutrauen
4 Kinalea Crescent
Stittsville, ON
Canada
K2S 1L1
Once I receive answers to my questions above, I'll place an order
accordingly. Thanks again!
Cheers & blue skies,

PS- on a side note, it was my understanding that the previous company
had a new cowling design in the works. Are you going forward with their
newer & assumed cleaner design? Would you have any pictures of it?

Subject: RE: Europa-List: Mod 72 question
O.K. Bob, you woke me up!
Rob Housman's answer is on the ball. Using Redux would necessitate
increasing the clearance between the original tube and the new inserts.
The
Redux would not be strong enough to withstand the bending load, which is
the
critical part of the overall stress. The insert is intended to be a
close
but not interference fit in the outer tubes after reaming. Any small
clearance which may exist after fitting the new tubes will be taken up
by
deflection caused by the initial load applied by the weight of the
engine
and propeller.
The bending load is applied both by the vertical load from the weight of
the
engine acting some 2.5" approx forward of the weld affected area, and
also
by the small tube which is about 1" above the main horizontal tube. The
forward thrust from the propeller creates this bending load. To that
has to
be added on one side the torque reaction. (Distances are from memory as
I am
writing this fom home).
I have made a small change to the Mod leaflet to make the applicability
criteria a little clearer. The factors which affect applicability are
engine and propeller weights and c's of g forward of the undercarriage
mounting frame, and the engine torque.
Briefly all Rotax engined Europas, except those with classic engine
installations and light propellers as defined in the Mod leaflet, will
need
to incorporate the Mod. So all Rotax engined XS models, regardless of
whether 912, 912S or 914, and regardless of propeller will need the Mod.
Europas with engines other than Rotax will need to be checked on a case
by
case basis. We have already established that Europas with the Jabiru
3300
engine will need the Mod.
It was orginally intended that the news of the Mod would be promulgated
by
the PFA and EA4 on their respective websites simultaneously -
unfortunately
that did not happen. The PFA have now updated their Type Acceptance
Data
Sheet to include Mod 72.
We realise that quite a long time has elapsed since the failure took
place
that gave rise to this Mod. It was necessary first to establish that the
failure was not a one-off due to a unique set of circumstances; research
into the original calculations established that there was a more general
problem. The we had to devise a satisfactory solution that would be
reasonably straightforward to incorporate, then carry out tests to prove
the
fix. Then the method had to be agreed with the PFA, and the Mod leaflet
written. This latter exercise proved rather drawn out, and several
drafts
were needed before the current version was agreed. Establishing why the
original error in stressing was made during the reign of EMIL proved
almost
impossible, as the engineer concerned died a few years ago.
I realise that many people may feel that an unnecessary fuss is being
made
about this Mod, but a look at the attached photo of the first, but not
only,
failure should prove interesting.
Best regards,
Roger Bull

Subject: Europa-List: Mod 72 question
Fellow Europaphiles,
The Mod 72 topic has become too quiet. I've decided to give it a poke
and
see if I can wake it up again.
I have all the various bits for Mod 72 on order. Etching primer,
ACF-50,
16.5 mm hand reamer & Mod 72 kit.
I am wondering why the heavy wall tubing is not bonded in place with
something like Redux.
Is the press fit good enough to support the frame?
Would it be better to Redux the insert in place? Better support and
corrosion protection?
If not, why not?
Good building and great flying,
Bob Borger
Standing by, wearing my nomex undies, ready for the flames.
P.S.
The reamer will be available for loan to any Europa builder in the U.S.
or
Canada who needs it for Mod 72.

Jos,
I haven't seen any directions before, and would love to find some.
With that said. The ramp for the monowheel when in the up/retracted
position goes over the outside of the landing gear frame assembly and holds
the airframe upright. What you should be aware of is depending on how you
secure the ramp in the up position can vary the angle in which the airframe
is positioned. I use chain the secure the ramp in the upright position and
turn buckles to tighten up the chain. If I don't make sure I tighten the
turnbuckles equally I will get the fuselage setting on the trailer at an
angle. Depending on the degree of angle, when traveling down the road, the
rocking of the airframe may cause it to come in contact with the rear wing
support. This in turn can cause damage to the airframe.
Because it takes 2 people as a general rule (unless you have a trailer
winch) to push the aircraft onto the trailer, I made a ramp that lessens the
angle of the ramp that is on the trailer. It is a wooden ramp that they
trailer ramp rest on to lengthen the ramp and lessen the angle. With this
done I can push the aircraft on the trailer by myself with my wife only
having to hold the wings level.

Yes, Ted's strut fixing is clever and very neat but a little fiddly to

I think I shall go for the simple reversed fitiing if I can get

Will redux and rivits do the job on the bracket or will extra stiffening
be needed on the door edge?

A further complication with the tailer is that the mono tyre is narrower
than the channel it sits in. If the tyre isnt centred in the channel, the
fuselage will still lean to one side when trailering. This cant be corrected
by adjusting the turnbuckles of the ramp support bars.
Easiest solution is to bond plywood strips to the sides of the wheel channel
(only at the bottom where the wheel sits) so that the tyre is a snug fit and
centred in the channel.
Also if the ramp is taken up too far or/ and the tyre is under inflated, the
top of the ramp floor (in the raised position) will rub against the upper
portion of the swinging arm causing wear and possible weakening of the
undercarriage. A strip of tufnol or rubber should reduce the possibility of
this happening.

Hi Jos
Mine came from the factory sans instructions. I have increased the diameter
of the wheel so the ramp would not go up enough to put the aircraft on. If
you have a larger wheel than that originally supplied, email me off board
and I will tell you my solution.

hello Roger,
First of all happy new year!
We have made a check of our airplane to day with Alain Chabert and no
discover a failure on the engine support.
We read the mod 72 document and the mandatory classification is made by the
PFA only not by Europa company.
Question 1: On how many aircraft do you detect this type of failure?
Question 2: Do you have precise pilot report on the exact landing situation,
and on how many landings?
In example, some pilots have habitude to made hard landing and for us it is
normal situation.
Roger, thanks for your assistance

to incorporate the Mod. So all Rotax engined XS models, regardless of
whether 912, 912S or 914, and regardless of propeller will need the Mod.
Europas with engines other than Rotax will need to be checked on a case by
case basis. We have already established that Europas with the Jabiru 3300
engine will need the Mod.
It was orginally intended that the news of the Mod would be promulgated by
the PFA and EA4 on their respective websites simultaneously - unfortunately
that did not happen. The PFA have now updated their Type Acceptance Data
Sheet to include Mod 72.
We realise that quite a long time has elapsed since the failure took place
that gave rise to this Mod. It was necessary first to establish that the
failure was not a one-off due to a unique set of circumstances; research
into the original calculations established that there was a more general
problem. The we had to devise a satisfactory solution that would be
reasonably straightforward to incorporate, then carry out tests to prove the
fix. Then the method had to be agreed with the PFA, and the Mod leaflet
written. This latter exercise proved rather drawn out, and several drafts
were needed before the current version was agreed. Establishing why the
original error in stressing was made during the reign of EMIL proved almost
impossible, as the engineer concerned died a few years ago.
I realise that many people may feel that an unnecessary fuss is being made
about this Mod, but a look at the attached photo of the first, but not only,
failure should prove interesting.
Best regards,
Roger Bull

Subject: Europa-List: Mod 72 question
Fellow Europaphiles,
The Mod 72 topic has become too quiet. I've decided to give it a poke and
see if I can wake it up again.
I have all the various bits for Mod 72 on order. Etching primer, ACF-50,
16.5 mm hand reamer & Mod 72 kit.
I am wondering why the heavy wall tubing is not bonded in place with
something like Redux.
Is the press fit good enough to support the frame?
Would it be better to Redux the insert in place? Better support and
corrosion protection?
If not, why not?
Good building and great flying,
Bob Borger
Standing by, wearing my nomex undies, ready for the flames.
P.S.
The reamer will be available for loan to any Europa builder in the U.S. or
Canada who needs it for Mod 72.

I may be confused, which is most of the time, but the only way I can keep the airframe
secure in the vertical position is with the ramp in the up position sliding
over the swing arm. I have a fat wheel that is a nice fit in the bottom
section but that alone would never hold the airframe vertical.

Happy that i am not the only one confused. I've seen monowheels with scratches
on the top side of the swing arm, and thought it to be caused by the ramp, locked
up position. On the trailer i have, the ramp does not reach high enough to
grab the swing arm, not with with the original adjustment. I have not raised
the tailwheel yet, maybe that just makes the ramp grab. But clamping the the
tyre alone does not hold the fuse vertical, not when forces are exited anyhow.
Who resolves the puzzle?

Hi! All
I have a friend who is looking to change his rig over to toe
brakes/combined rudder pedals.
We know there's two aircraft out there with this facility , to save
"re-inventing the wheel" so to speak can anyone shed light on which
aircraft and any contact details of the owners concerned?
E-mail me directly please at ptag.dev@tiscali.co.uk

Hi Jos,
Do you have the engine installed yet?
With the weight of the engine, the suspension is compressed, and the
swinging arm will be captured by the ramp.
The rod ends on the ramp tie rods can be adjusted to raise or lower the
height of the ramp, to suit.
Tufnel shims on the inside of the ramp will prevent marking the swinging arm
[ don't paint the arm].
Tufnel or plywood blocks on the bottom of the ramp, will keep the tyre in
the centre.
Cheers,
Nev.

Jos
the gear leg is supposed to sit in the channel section that holds the
wheel on the trailer. Trouble is it tends to bounce and when it does it
will hit the wings. I always use a luggage strap over the fuselage just
in front of the screen. That holds it firmly in the channel

Thanks Nev,
Yes, the engine is on, and i expected things to happen as you describe, but it
did not. The plane which used this trailer before must have been quite a bit heavier.
Will adjust the rod ends then.

| Subject: | Thoughts on rudder trim needed? |
Our Monowheel XS with a 914 and Airmaster has both short and long wings.
Will have servo trim tab for roll on both. Will fly short first for a
while.
I was wondering if I could get opinions on rudder trim.
Is it worth it to install inflight adjustable trim?
Or is it possible that somehow we managed to build an airframe where both
sets of wings would need no rudder trim? Flies straight in thermal soaring
mode with long wings, as well as heavy fast short wing flight.
Or if rudder trim is needed it is more of a fuse thing, and if needed a
double sticky tab is all that is needed and would work on both short and
long, and for the most part rudder trim is just not that speed sensative?
If there was a slight difference between short and long, a calibrated by
eyecrometer bend on tab, or added 1/2 of a flettner strip for a given wing
makes the most sense?
Anyone have an inflight adjustable rudder trim that they think is a great
feature? Like have an airplane that at different speeds requires different
rudder trim and being able to adjust just adds to the pleasure of flyin?
If yes what is dimensions of trim tab you use with how much deflection?
Thx.

I sure don't need rudder trim on mine. Flies very straight at all speeds
with no rudder
trim tab. When I fly with a 200 lb passenger, I can just rest my left foot
on the rudder
pedal to counteract small right roll tendency. For long flights with a
passenger, I have
a small bolt on rudder trim tab but I haven't even used it in 3 years. Lots
of extra
complication for no benefit!
