Hi Ferg,
I was about to respond when Nev replied with the same suggestion.
I have recently worked on two XS Mono kits that have been well stored
(warm and dry) for the last twelve years.
As a matter of course, I strip and inspect all components before
assembling and on both I found that the brake slave cylinder pistons
were stuck fast.
Using a compressed air line to pop them out, I discovered that both were
covered in a glutinous substance (see Picture).
I am not sure what this is but would hazard a guess that it is old
hydraulic fluid that would have been used to lubricate the piston during
manufacture and being hygroscopic, has absorbed water over the years and
degraded.
I would suggest dismantling all of your hydraulic components and
carefully cleaning and reassembling with fresh hydraulic fluid. I pretty
sure that you will then be able to bleed the system as described by others.
As an aside, I am certain that this is the cause of high brake disc and
pad wear with associated hot discs that other mono pilots have
complained about over the years.
If you intend to keep the aircraft and have a desire to reduce
subsequent maintenance, I would also highly recommend having all the
components anodised. I have done this to mine and can send picture
offline if you are interested.
Nigel

Subject: Europa-List: Beringer wheel/brake for Mono wheel
Just finished the installation of the Beringer wheel/brake kit into my
Europa mono wheel, OE-CKD:
I use Beringer's hand operated master brake cylinder (MP-004.3) with remote
mounted brake fluid reservoir, mounted on the centre console (same position
as the original);
no modifications to the slot and holes for the fixing screws on the centre
console are needed!
(some minor modifications on the master brake cylinder are needed to fit
into the centre console)
The Beringer kit came within one week after ordering, is superbly made,
works perfectly and telephone Support from Beringer is excellent!
They use the AirTrac 7-6:00 tire (without tube), which comes already mounted
on the wheel together with the brake.
Total weight saving: 2,5kg - I weighted all Europa parts: 11,8kg - all
Beringer parts: 9,3kg; both with AirTrac tire
It took me about 6 hours to install the kit.

It's been a few years, but yes I recall some of the bolts called for were
too long without the use of many washers to pack out the space
So I opted to go down one size I seemed to have a lot of extras of most
sizes so I didn't need to order them

Ferg,
I had an experience similar to Nigel. My unit had been stored for a
similar time.
After soaking in various fluids for several weeks, using heat and
compressed air to no avail, I borrowed the hand pump from a hydraulic
press which finally shifted to piston.
The piston was dry and so badly corroded I turned up a new one, also
adding concentric grooves to the rear face to allow fluid easier access
to the piston when fully retracted. The bore of the cylinder I was able
to salvage.

| Subject: | DOT4 and filling the monowheel brake system |
My great thanks to Max, Remi and Neville for help.
The fault was mine, the stupidy rampant. I discovered a stuck
piston in the reservoir/lever component, due to deterioration in the piston
rings/cap - sitting for 5 years without inspection. The jammed lever gave
clue, so opened up the piston area, replaced the cap and ring and cleaned
it. Perfect BUT forgot the condition when I installed the system and ignored
the brake cylinder.
There we were, squeezing wildly on the syringe, dripping fluid
all over the place. Finally sense slowly prevailed, I took out the brake
cylinder and the piston was frozen solid. Took it to a nearby brake repair
facility and in twenty minutes we had it cleaned. (Thanks, Neville)
I bought another horse syringe, clipped the nozzle to increase
the end diameter to fit and screw into the top master cylinder filler,
(Upper Syringe). I then borrowed a neighbour's boroscope and aimed it at
the upper syringe so I could monitor progress while below..
Re-assembled the system. Then I created a suction by pulling the
upper syringe to get some suction. Loaded a 600 ml syringe and applied fluid
to released bleed valve below. Magic - flowed in like water... When the
boroscope showed fluid bubbling into the upper syringe, I pumped the bottom
one until no more bubbles arose in it , pulled the bottom to drag the
meniscus down to the cap level and removed and capped the master cylinder..
Pulled the bottom syringe, closed the bleed valve, and tried the lever.
Pressure, no spongy response and the wheel brakes.......!
Now I know if I had checked both cylinders properly, read the clues and
thought a little more about it, I wouldn't have disturbed my buddies, would
have done the job, and saved gas, 15 dollars, and a day's exertion, plus the
celean-up........
Thanks again, Max, Remi and Neville!

Hello.
I am not 100% sure on this myself, as I have been Retired for some years and no
longer a CAA Examiner.
But just posting the comments of a friend who is a currently an Examiner.
He seems to think you can not do an IMC rating using a Europa.
It must be a certified aeroplane with the appropriate licenced equipment.
So it would be wise to check this out for yourself if you are talking about a UK
rating, I asked the question just out of interest,as I have an nppl and no interest
in an IMC Rating.
Regards.
Alan

| Subject: | 912 914 Carb Rubber Flange |
I have been working on a replacement carb mounting flange for the Rotax 912 and
914.
The rotax flanges are known to crack and come off the metal flange. These new flanges
are aluminum flanges tha use a rubber joiner to connect to the carb with two clamps.
All that will ever be needed to be replaced is a $3 rubber. I have a few of these
made up
and am looking for someone in the US that is interested in trying a set of these
and reporting their
thoughts on them.
If anyone is interested please email me off list to discuss it.

| Subject: | 912 914 Carb Rubber Flange |
We used to use similar on small motorbikes that had 25mm and 32mm carbs, worked
well, the
Original mounts would always break off at the plate end of the tube, changing the
tube length
Can allow some "tuning" of the intake as well, but the effect is limited unless
you alter the exhaust
Length as well, which in this case would be hard.

| Subject: | Fuselage weakness, or intentional ?? |
Gidday,
Whilst working around in the lower fuse it has concerned me that my fuselage
has what appears to be an intentional absence of core material such that an
obvious weakness exists in the fuselage directly above the penetrations for
the flap drive cross tube. Has anyone externally reinforced this area, by a
dding core material and strapping it in place, encapsulating it, and resulti
ng in a conventional sandwich construction concept?
