How about an article for the Europa Flyer? It would be nice to know how you
achieved the near impossible ("I can see it, I can touch it, but not at the
same time") installation of the bell-crank assembly in a completed aircraft.
If it seems possible for normal mortals (not Dutch) I can add it to the
instructions.
I need all the help I can get to get the documentation right (as no one at
Europa can help).
The parts list, on pages 1 & 2, should be correct so please let me know if
you have spotted any errors. Any other parts supplied in error needs
reporting back to Europa.
As you say the rivets supplied would have been TLPD435BS. Apologies, I
missed the reference in section 3.6 to the original (AN470-AD4-10) rivets
which they replace. This change was made as few builders have rivet punches
to form nice heads on solid rivets.
I have already added a reference to refinishing the base of the rudder to
the latest revision.
Best wishes

| Subject: | Jacking up the mono |
I am wondering what the best method is, to change tyres etc. I brought a couple
of trolley jacks to put under the wing spars (with wooden blocks) but it still
needs something under the nose and there isnt a good jack point.
I guess I could use an engine hoist from the top but that all feels complicated.
There must be a common solution.

I made a 'goalpost' support out of 40mm box section with a 20 bottle jack to lift
it. Mail me off forum and I'll send photos.

There is a couple of examples of Mono jacking on the Club Web site (http://www.theeuropaclub.org/for-pilots/trailers/handling/)

I always carry a "jacking piece" welded for me, which can be bolted to the front
of the undercarriage swinging arm, after removing the lower two of the existing
four bolts whose heads are in a cluster. For stability I always use a trolley
jack in preference to a bottle jack. Remember to put the bolts back afterwards.
On two occasions I have used a stout piece of timber with length equal to the width
of the fuselage and padding placed between it and the fuselage bottom. This
timber is placed as close as possible to the rear of the main wheel and at
the rear end of the wheel bay. Again, I use a trolley jack and there have never
been any crackling sounds while the fuselage is being lifted.

Hi Monowheel drivers,
I broke one outrigger leg two months ago and flew for a while with an emergency
repair designed on site just to allow me to go back home: the repair was made
using the existing remains of the nylon rod lengthened with scrap aluminum tubing.
When I finally received the nylon rods ordered from the Europa factory I
could not use them because they were slightly too short and badly machined. So
I ordered a length of 1"1/4 Nylon from ACS and installed them immediately. At
the first landing, one of the all new legs broke just at mid length. I was very
embarassed as this happened on a big airport were I had the honor of a jumbo
eight wheeler fire truck! This time I managed to repair quickly as I was carrying
the old emergency repaired rod in the aircraft. I am now afraid of flying
with the aircraft as it is, as an out rigger leg can break again at the next
landing.
My questions:
- How is that possible that a new nylon rod breaks at the very first landing while
the original parts have been able to withstand 12 years of aging, 950 flight
hours and probably one or two thousand landings, some of them not as smooth
as they should be?
- How is that possible that the nylon rod broke right at mid length, which is not
where the maximum stress is located? Note that the first leg broke at the upper
end which seems logical to me.
- What is the experience on other monowheels regarding the life of those nylon
rods?
- has anyone designed and tested a variation of the original outriggers, with rods
made of other materials such as glass fiber, steel...?
Regards
Remi Guerner

| Subject: | Jacking up the mono |
This thread is of great interest as I'm nearing the end of my build.
As I've pondered this issue, I'm thinking that the ideal mechanism
would do the following:
- stabilize the fuselage when wings are detached,
- function w/ and w/o the cowl attached,
- allow for changing of tire and tube,
- allow for testing of LG retraction and deployment,
- allow for the airplane to be easily moved about a hangar in any
direction...think of hangar-sharing w/ other aircraft.
To accomplish these goals, I've been thinking about some kind of
platform/dolly with 3 or 4 castering wheels of sufficient size to roll
easily on turf, gravel, or concrete combined w/ a hydraulic jack and
some kind of a cushioned cradle...
Perhaps...in my innocence...I'm over-thinking here, so I'm very
interested to know whether or not those who have been flying,
hangaring, transporting, and maintaining their aircraft have dealt
with these issues with any equipment other than the standard trailer.
Comments and experience appreciated,
Fred

Hello, Frans,Bud,Dave.
Thank you all for your inputs,
Bud ,some nice photo,s your trailer looks like pretty Strong, I Hope i never need
a trailer for recovering my Europa from a field.
I have bought my Europa mainly for local flying in the UK, it would be nice to
fly in Europe, but if i had a problem with the aircraft away from home it would
cost to much for me.
I purposely purchased a Europa as the wings could be detached and the aircraft
stored off the Field, if needs be and money became short, the Europa fills this
requirement.
However i hate all flying Tailplane's, they belong to jet fighters which can take
lots of G.
I want a trailer Hanger, also to load nose first as i don,t want all the weight
at the far end. (a good point about the Spats ,Frans)
My concern was where to connect the tow line to the aircraft, to me the upper
main gear seems to be the strongest point, but i see many are using the nose wheel
with out any problems, so maybe i will use this point
to attach too.
Regards
Alan

Have you considered making some out of Kevlar, could be lighter and
stronger, and more forgiving than the nylon
As for the nylon, I have seen "casting" faults in some of the larger pieces
I have been given over the years. They
Looked like a light coloured line or hair in the nylon. For general use most
people wouldn't notice and it wouldn't
Have any effect on the performance of the product. Maybe you had one that
went undetected at that failure point, until you landed.
Good luck, no damage I hope

Remi,
Maybe a bad batch of legs supplied to the Company. Tell the Company and return
them for testing. They should send another pair out hopefully from a different
batch.
Cheers,

| Subject: | Re: outrigger legs |
Hi Remi,
I have had several outrigger legs fail. Some from bad landings. Others for no good
reason. It is my belief that the Nylon-66 does not easily show any signs of
weakness or eminent failure. So you can't properly inspect preflight.
I know from talking to other mono pilots that plenty of failures have occurred
for no apparent reason.
I started using fiberglass rod, 5/8" diameter. I use a 6" piece of the nylon-66
with a 5/8" hole bored thru the center to fit the fiberglass rod into the Outrigger
socket. I tapered the nylon from the bottom of the socket to the lower
end of the 6" nylon. I tested this on the bench and the rod has about the same
flex as the original setup, but when it fails, it is progressive and visible,
rather than shattering unpredictably.
I made new wheel forks out of steel to fit 4"inline skate wheels to the smaller
diameter legs. They seem no different in the way they perform from the original
shopping cart wheels, except they are urethane, have sealed bearings, and wear
quite well. Narrower, so probably less drag.
This setup has worked well for me and saved about 1.5lbs.

Hi Fred,
That's quite a list of stuff this thing has to do! But I bet it can be done. That
will be a handy hanger accessory.
I feel a need for a small, light, jacking block to use with most any jack that
would be part of my tool kit in the aircraft.
