Hi Karl,
Why wouldn't it work ?
It would pin the TP12 to the torque tube... but, think where the load from
the tailplane is at it's highest, yes, just before it goes into the brass b
earing bonded to the fuselage.............. and picture the torque tube as
a spar, you have just drilled holes through the spar caps..................
......................
The removal of the assembly, and reaming and fitting oversize pins is the
only way to go, quite easy as I have described, as long as you have access
to a good machine shop with guys there who know what they are doing, then i
t is almost guaranteed to be a success. WITH AN 0.007'' INTERFERENCE FIT T
HEY ARE NOT GOING TO MOVE.
Use Loctite or Bob's clamps after this fix as a belt and braces if you want
peace of mind, either of these without doing the pins first is not good en
ough.
Cheers,
Nev.

I notice that I also have 1mm play on one side. All the recommended solutio
ns seem really complicated.
And I believe that I have grease between the TP10 and the torque tube, so t
he Loctite would never last.
Why wouldn't this work ?: Insert another pin on the outside of the fuselag
e. There is a gap between the TP12 and the fuse skin. Remove some of the s
kin to gain access for the drill bit and the pin, the skin is easily repair
ed afterwards. Drill a hole through the top only. Then insert a close fitti
ng machined piece of aluminum rod, pre-drilled . This piece would have a re
movable handle screwed into it near the edge to facilitate insertion and po
sitioning. While rotating the insert apply Redux. Line up the holes again a
nd now drill the bottom hole. Insert the pin or bolt with locknut and remov
e the temporary handle.

Subject: | Re: Mod 73 - slightly different |
Hi Europa pilots/builders
I did the mod 73 per instructions five years ago and at first it looked
good. After a short while the play was back.
My assembly was perhaps a bit tighter then normal so the Loctite did not
penetrate enough.
In order to get rid of the play I made =9Cspecial=9D washer,
situated inside the torque tube. Now it was possible to tight the tubes
hard together.
The result was a zero play system. Complete solid for 5 year (340 hours)
. I know another builder that has solved the play in the same fashion
with complete success.
Here is draft drawing that shows the parts involved. In my case it was
only necessary to change the outer bolts:
http://aero2012.scassel.se/Images/tailplanemod.PNG
It is necessary to create a spanner with looong shank. I used a wooden
stick and strapped the spanner to it. After 30-40 minutes and some
swearing (not much) it was tight, very tight I may add.
Additionally I made a thin black line, 4-5 cm long, on fuselage when TP
trailing edge was fully down, parallel with TP skin. This reference line
makes it very easy to catch very small play over time.
So far the TP is still on the reference line. I check this on every pre
flight.

Hi Karl
That,s a good point Neville has mentioned ,the hole is on the outside of the bearing
support, i can see what he means ie look at it as a spare, better re think
on this one,
As for hole,s, to get at these pins, from the outside of the aircraft.
>From the inspection hole under on the side of the fuselage under the Stabilator
can you get to the pins to remove them,
If you placed an inspection hole in the fin above the tube this would seem the
best point to do all work from, But we come to the question would this weaken
the Fin.?? Bud mentioned a inspection hole ??

Karl.
I had forgotten about your solid core, so if you going to bond a solid alloy core
inside the tube spanning both side your dowel hole, then clamping up. i would
think that the tube is now stronger at that point, as you have re enforced
it.
If only the ruddy pins were accessible from a panel the job would be a piece of
cake.

I mentioned earlier I also went the solid core option, very quick and easy
to do,
However.. my lack of precision when drilling one of the outboard holes out

The 3/8 size resulted in a small misalignment between each of the tail

(About 5mm at the back) so I had to remove one set of the drive pin bushes
And re redux them in to correct this. I do however have my own lathe and

Slugs over here are pests in the garden , but i know what you mean,all good ideas.
Lots of solutions have been posted, But here in the UK the only options we have
are Resizing the pins, Fitting Bob Harrison or Pat Tunny,s clamps,
Re Loctite use, or fitting one of Europa,s updated tubes.
Anything about inspection panel and access to the pins would be really usefall
to UK owners, as the tube has to come out.

Hi guys,
Maybe if a slot is machined across the flat side of the specia

ong handle and lots of swearing :)

Alan-
There has been some discussion on here about additional inspection ports or changing
the size of those existing. As I recall, the recommendation was that you
have any such changes reviewed by a structural engineer before making them. The
concern is that these types of change may weaken a structural area.

Hi Alan=2C
Your points about access are very valid. You can just about get to the pins
=2C pull out the cotter pins etc. via the access window and viewing window
every Europa is supposed to have=2C but it is a real bitch.My idea was to r
eplace the round access hole with a larger rectangular opening=2C suitably
re-enforced=2C but I was unable to get any engineering support on this. The
idea of having to crawl into the fuselage for maintenance and mods is abso
lutely absurd.Craig's and my ideas about the solid core are just common sen
se. I will do my fix just as I described=2C but it is not on the top of my
list at the moment. If you can get the faulty TP14 pin out=2C then you can
do the same=2C but you probably wouldn't be able to tighten the pin or bolt
=2C because there is no space at the back of the tube for a locknut=2C just
a washer and cotter pin (at least on my Europa). You can still remove any
play by turning the insert hard against the pin before the redux has cured.
You are then as good as new and don't have to tell anyone about it.
Cheers=2C
