Hello Hans !
Hope you are well ... in The Netherlands ... or in Florida 8)
A little while ago in August you sent me an e-mail
regarding installation of an EFIS on your European registered Yak-52 PH-YAK.
Sorry I did not reply straight away ... Have been very busy lately,
older daughter starting University in The Netherlands (TU Delft),
father passed away on Friday 5 September, BA flying keeping me away from home ...
just arrived in So Paulo after a 11 hours and 13 minutes flight ...
Cannot find your message in Mailbox so posting on the Yak-List.
Our American friends cannot help you on this one because like George and Dennis
mentioned,
they are lucky in the US of A, Yaks are EXPERIMENTAL
and installation of new equipment or modifications are no big deal
with the pragmatic approach adopted by the FAA.
But all is not lost because installation of EFIS is approved by the UK CAA.
And it has been for a while.
I really wonder on what basis the Dutch CAA would ban you to install
an EFIS in your Yak-52.
I would also find this quite ironic because for years they were happy to let Yaks
fly
in The Netherlands with illegal Certificate of Airworthiness ...
(Just a quick reminder : Yaks cannot get C. of A. because they are Annex II aircraft
and that's why the UK CAA has always been issuing Permit to Fly to them
and why they are EXPERIMENTAL in the USA ...)
The Dutch CAA (like all other CAA in continental Europe) had absolutely no control
on what was going on regarding prescriptions from the manufacturers (YDB) regarding
Life Items,
Airframe Life extensions, propeller overhaul. Engine TBO, ...
Different European CAAs have different ideas ...
For instance the French CAA is quite happy with installing fuel bladders ...
'Plug conversion' is EASA approved
http://www.yak-52.com/downloads/ac12419.pdf
The Belgian CAA has absolutely no clue about dealing with Yaks ...
Hopefully UK registered Yaks will soon be administrated by the LAA.

But to answer your specific issue of installing equipments in Yaks, Hans,
your best port of call is probably the UK CAA itself.
Or contacting people dealing with Yaks in the UK, Richard of course, Yak UK
(they installed a DYNON EFIS - D10A in our Yak-52, see photo attached),

my friend Jez Hopkinson from the YAKOVLEVS formation aerobatic display team.
He has installed EFIS (and Garmin GNS 530) in all his Yak-50 / Yak-52.

http://www.yakovlevs.com/wp-content/gallery/aircraft/img_0332.jpg
http://www.yakovlevs.com/wp-content/gallery/aircraft/cockpit.jpg
...
Anyway having said all that, installation of an EFIS is a good idea if you do a
little be of travelling with your flying machine.
I decided to install the Dynon D10A a few years ago after flying
for 45 minutes in clouds coming back from the South of France
(a 4 hour 15 minutes flight) with my wife and our little dog in the back seat ...
I had to fly with a constant 5 degree of bank on the Russian Attitude Indicator
to stop the compass indicator from slowly spinning, trying to maintain a constant
heading to get us home.
Since then I had the opportunity to use the Dynon Artificial Horizon quite a few
times going places for Airshows
or coming back to base in less than ideal weather condition.
Quite a few missions I would not have been able to complete without it.
So highly recommended. I would not trust the Russian horizon installed in 99.9
% of Yaks.
Voil Hans, hope you will have an EFIS installed in your Yak soon.
Off with the Crew to the nearest Churrascaria on Paulista for some meat
and a couple of glasses of red wine :D Cheers, Etienne.

Thanks Etienne for the info. I am just going to build it is and see what happens.
Can you also send me the two previous emails please. My macbook just crashed and
I lost the emails because they were not in the backup of course.
Thanks!

As I recently sold my Yak-52TW it may be inappropriate of me to comment, but:
I owned my Yak with an M-14PF for 13 years. Without fail, EVERY time I moved the
throttle full forward at shutdown I experienced a fire in the carb intake. After
emptying a Halon bottle to stop the paint on the bottom of the cowling from
burning any further I quickly decided this was a bad idea. I NEVER had such
an experience with leaving the throttle at idle. YMMV, Batteries not included,
past performance is no guarantee of future returns....

Etienne,
Are you using the RMU gyro or the internal gyro (oscillometers) in you D10. I have
one in my 50 and love it. Have not put it in the 52 yet.
Thanks,
Doc

Etienne, your information about the French authorities is inaccurate.
They are not at all "quite happy" with fuel bladders, it is considered
being a major modification.
But they are willing to consider it as a possibility because the French
inspection understood that Dennis' bladders are a good replacement.
Fuel bladders won't crack when flying serious aerobatics.
You are very familiar with that problem.
So they allowed me to continue with the bladders.
The French authorities are still making a detailed inventory of all the
Yaks in France.
The French inspectors are very knowledgeable AND they are open for
pertinent arguments, fortunately!
Sorry to hear about your father, bad news!
BR,
Jan

Strange, I have an M14R (450 PS) and I always stop the engine with full
throttle at shutdown.
I cut the mags when I see the oil pressure drop significantly (when
reducing power), and then throttle full forward.
The supercharger in the M14R loads up to 1150 mmHG at maximum so I do get
some fuel.
There must be another reason why it fires in the carb intake.
