Alan,
I am just getting around to the europa list this week. Lots going on in
the Europa world and many folks are doing new and interesting stuff
keeping me busy.
Regarding your woes:
Our fix with the Loctite is quite strong. I use a firm grip on the
trailing edge and try to wiggle it up and down and it should not move.
To check on a 25 hour inspection or after other maintenance where the
stabs are removed, I apply a firm force (20 pounds) on the leading edge
to assure the Loctite is tight and the small amount of slop is removed.
I prefer the pins to be properly installed. Some new builders can't
drill a straight or round hole so even if it were bolted, their work is
loose.
Your lack of building review or knowledge is really not a problem.
Review the manual on line and note that for the stab to be placed where
it is, it must be removable and installable, and it is.
As for checking the stab on routine flights. It is just like a Cherokee
or similar all moving stab. Check for excessive play, such that you can
hear some movement but the control is solidly attached and it does not
move un-commanded by the stick. For an example, if the front door
rattles when it is closed on your house, you adjust the stop and latch
to fix it. It is just proper maintenance and security. Others put a
thicker door gasket on to fit it. I prefer to fix it right, but the the
gasket works also. So does the Loctite.
As for repairs: I am an advocate of finding a repairman that is
familiar with the type, or if no one is available to help, a good
builder who has gone through the trials is your best bet. I would
prefer in the UK you take it to Nev Eyre or the factory. If I find a
really poorly built tail plane torque tube, I go ahead and remove it
---From the aircraft and put it together on the bench. I note the problems
and will normally build new pins or install the 3/8 inch pins if not
modified. I do not blindly follow the instructions and just hand drill
the pin holes. I go to a machine shop and have the holes precisely
bored to the pin size. If the holes aren't true I square them and have
a pin machined to zero tolerance. Then fit the torque tube in the
fuselage again and freeze the pins on dry ice to shrink them and then
rapidly install them. The pins warm up and get really tight. I then
finish off the task by adding the Loctite. It is done then and should
be good for many, many years. While they are making repairs, why not
make the inspection holes slightly larger so you can work and inspect
easily. I do, and it is easy to work on anything in my or my customers
tail area.
Those who have excessively sloppy tail planes should consider removal
and pin replacement. Also if there is excessive play, change out the
bushings in the stab as they do wear if the play is excessive.
A good machinest will know his tools, capability and be able to make
everything right. Someone like Nev, or the factory can fix you right
up. Many experienced folks on this site will be able to help also, but
it takes time and a proper shop as winter is approaching.
Remember, Stab control is not lost, we are preventing flutter potential
with the Loctite should the builder not quite get it right.
If you can move your stabs independently more than a fraction of an
inch, by grasping them with your hand and applying force, your pins are
a bit too loose. Time to fix it.
Once fixed properly so there is no play, enjoy the delight of the pitch
control system.
Keep a positive attitude and remember the above and enjoy your airplane.
And please don't blame the original builder, as we are all amateurs
with our first plane. I spent 450 man hours to bring my really great
deal flying used kit up to my standards (remember I am anal retentive
about airplanes and maintenance) and it flies great. That said, I was
finishing up my annual inspection and found my turbo bracket cracked,
and the Binx nut holding the bracket was gone also, most probably due to
turbo vibration. Oh well, it is just time and money. The turbo will go
to Garret, and Lockwood Aviation will get another chunk of my money for
parts. Ah aviation.
Regards,
Bud

Hello Bud.
Just read your posting, and as a pilot and not a builder this part of
the aeroplane has given me concern since i purchased the aircraft.
I notice you have used Sloppy and Band Aid Fix and that,s just what it
looks like to me.
The problem in my case not being a builder, is lack of skills and
materials to fix the problem,and not knowing who to to take the aircraft
too, to have it repaired.
In my opinion, which seem,s to get me into trouble, I think the
manufacturer should assign designated repair centres with the skills to
carry out a major modification as this.
I can manage without a prop, i can manage without an engine, but i can
not manage without Stabalator control.
This part of the aircraft is vital for survival and as i see it the
most vital part of the aircraft, more chance here than the spare.
Why was,nt this complete component made welded and machine finished
unit,
with the pins that drive the stabalator mirrored into a pre
manufactured plate that's moulded into each stabalator, Which would give
no play.
Before i fly again i will do all you external checks.
But im not sure how much pressure to apply, it is difficult to know as
people have different ideas of force, but say the amount the same as to
lift 1/2 a bucket of water.
Regards
Alan
