Check your bolt lengths, when all assembled ( including gaskets) you should

You should not need either!! Replace the rubber with cork gasket material,

See above, just clean it off.

Hello William,
I am also in the process of fitting the wema gauge in my fuel tank on a new buid
- it also will be accessed later through the port headrest.
I don't know what you've ordered from las but I've sent for PR1422A fuel tank
sealant.
Mine only came with a rubber gasket, so the sealant is mainly for the bolts although
I will use it on
both sides of the gasket as well as the bolts,
Steve. # 630

I did the same when I put the fuel sender in though I did it with the tank
out of the aircraft. Now I look at it and wonder how on earth I am going to
service it where it is...Someone suggested a much better place which would
be between the headrests under an inspection plate.
Does anyone have any ideas about how to access the sender unit once one has
it in place under the head rest...errr perhaps turning the whole headrest
into an inspection plate - cutting it off at the base and putting a base on
it and bolting it down? Ideas anyone?
Will

Will,
I had to put mine under the port headrest due to the length of the sender unit
- it would fit between the headrests.
however, where I've put it - next to the port headrest access hole, it is removable
through that hole - perhaps yours is also ?

| Subject: | Tailplane jammed on with corrosion. |
On behalf of another Europa builder/pilot who is a good friend, I appeal for help.
To put it mildly, we're getting desperate. Water found its way down one of
the pip-pins and corrosion has spread several millimetres around the lower hole
through torque-tube and bush, if the corrosion on the pin itself is anything
to judge by.
I first drilled and enlarged two holes through the flange underneath the tailplane,
large enough to pass a screwdriver through and levered initially between
the drive pins and rib to ensure that they weren't stuck.
Then I enlarged the holes sufficiently to allow a foot-long screwdriver through,
pressed its tip between the inboard rib and drive plate, clamped mole grips
to the screwdriver shaft and proceeded to twist the tip each way. No luck.
After blocking the drain hole underneath with tape, we drenched inside the pip-pin
hole with ACF50 and using the advice given by Neville Eyre drove ever more
tongue depressers into the gap between the flange of the tailplane and the side
of the fuselage. This creates considerable outwards force.
We left it for several days and returned to find that nothing had moved. Using
a wooden block and hammer, we hit repeatedly against the exposed end of the torque
tube in the vain hope that shock waves might get things moving.
Finally we drenched the area again, this time with WD40 in the hope that it might
penetrate the corrosion more effectively and left it again with tongue depressers
in place and our fingers crossed.
Our great fear is that the corrosion has taken hold under the nickel plating on
the torque tube and caused it to bulge against the inside of the bush, in which
case everything we're doing and have done probably won't work. We know that
local heating isn't an option and I've even contemplated sliding a small piece
of dry ice along the inside of the tube (past the 4 pins), but don't know what
extreme cold might do to the foam/resin.
Before we resort to cutting open the bottom of the tailplane and doing major surgery,
please could someone tell us of any other trick to try. It's amazing that
seemingly no-one else has ever had to deal with this problem in the Europa
family. Is there some other fluid we haven't heard of which definitely won't cause
harm to the surrounding materials?

| Subject: | Re: Vertical trim friction device |
Hi Frans,
I believe the main purpose of this friction device is to prevent all the aerodynamic
loads on the tabs to be supported by the little plastic linkage and gears
of the RC Allen servo. It also prevents a catastrophic failure to occur in case
of breakage of this linkage between the servo and the friction device. So
obviously it is a very important safety feature.
On my aircraft I once observed an important slack in the friction system which
was due to the M5x60 bolt and M5 check nut on the bellcrank TS03 becoming loose.
This was easily fixed with Loctite. I also found that adjusting the spring
preload to the minimum and greasing the friction surfaces was better.
Regards
Remi Guerner
