I am considering to exchange my (inoperable) Attitude Indicator with a Dynon EFIS.
Has any body done this? Are there problems with FAA certification?

Thread Title : Dynon EFIS 10, EMS 10A, and HS34
My new bird, 200.175, that I just picked up from Ximango USA had the Dynon EFIS, EMS and HS34 installed. So that can be a reference for you.
Check with those guys. I was covered under the new bird provision provided by the factory and its agents. However, this standard may make it easy to get a 337 done, if that is needed.

Thread Title : Dynon's response
My attitude gyro was out for repair 4 times in 10 years. Never worked longer than a few weeks.
Those EFIS look very nice. Both features and price.
I sent an email to Dynon for advise about installing non-TSO'ed gear in certified aircraft. Here is the response:
Hi Roland. Yours is a very common question for us.
Our equipment is not TSO'd, STC'd, or otherwise certified for installation in type-certified aircraft. It is designed for use in Experimental/Homebuilt aircraft and in Light Sport aircraft.
There is a process for installing some types of non-certified equipment into certified aircraft through Field Approval, which relies on documentation using the FAA Form 337. While it may be theoretically possible to obtain FAA field approval for installation of one of our EFIS displays in your aircraft, the Dynon EFIS products need to be permanently mounted and require pitot, static, and power connections. Therefore, it is unlikely you would be successful in obtaining such a field approval. We do not provide supporting documentation for any Form 337 applications.
We appreciate your interest in our equipment and hope you may find the opportunity to use it in other aircraft in your flying future.

Thread Title : Another email from Dynon
One follow-up note regarding your inquiry. We are not experts in the certification of gliders and motor gliders. It is possible those certification requirements may differ in such a way as to permit installation of equipment such as ours.
We recommend you contact the aircraft manufacturer, or possibly their US representative/dealer, to inquire further.

Thread Title : N175XS Dynon Installation
My installation was handled by the factory and tuned/extended by Ximango USA. They might be able to give some guidance on the installation. Normally, 337s are easier to get if there is a factory reference.
Note I think Dynon would be cautious since their system could be used for night and/or IFR in other type certificated aircraft. Since ours is limited to day/VFR I think we should be easier to convince the FAA to consider a 337.
To motivate people to check it out I have a very brief video here (use free Quicktime Player). Note you can right click the link to download the file, it's about 4MB.
Link: Dynon_Snippet.mov (http://www.xopa.org/kb/kb_upload/media/Dynon_Snippet.mov)
I will try to do a video in the future showing the various functions. I use the EMS a lot and the EFIS a bit, but mostly during trips.

Thread Title : Chuck believes FAA will approve EFIS installation
Yes, it should be able to be done. We have now delivered about ten new Ximangos with Dynon EFIS 10A's installed, all factory-certified and approved by the Brazilian ANAC and the FAA. Based on that history, Jerry Owens has recently obtained 337 approval of an installed Dynon 10A EFIS in an older Ximango, SN 52, I believe. Jerry has the details. He's vacationing a lot but I think can be reached at jowens1824@bellsouth.net. Please keep us posted.

My 200S came from the factory with a D10 installed. It cratered and was upgraded by the previous owner to a D10A. You're welcome to use me as a reference if it will help you get a 337 approved.

Cliff and Steve (and other owners with Dynon EFIS installed):
Would you be willing to post a copy of your airworthiness certificate and a picture of your instument panel? This might help to get a field approval for retrofitting D10A's in older Ximangos like mine.
I talked to Eric Bubny, the avionics inspector at my FSDO in Philadelhia. Here is what I learned:
The easiest and fastest way to get an approval to install non-TSO'ed avionics is via a Service Bulletin issued by the airframe manufacturer. I asked Chuck to try to get an SB from Aeromot. That will take some time.
Short of that my FSDO must work through an FAA enineering office located somewhere in NY to evaluate the case and get a so called 'field approval'. To speed up that process anything that shows prior evaluation by FAA of similar cases is helpful. This includes names and numbers of inspectors who signed the airworthiness certificate of aircraft imported with such equipment.
An other way to speed up the process is to present approved 337's for similar cases.
If anybody has such a form, please share it with us.
I cannot wait to get a new gadget in my old bird.

My panel & airworthiness certificate pic files are attached. Hope they are helpful.

I emailed Jerry Owens several times - no reply.
Do you have a telephone number?

do you have a document which shows that the installation/upgrade to the D10A was approved? Equipment list which shows D10A? I am starting the 337 process.

in the picture of your panel I see a variometer. Did you or the previous owner do a 337?

Hermann -- the original equipment list from Aeromot shows a D10. The original one failed and was upgraded/replaced with a D10A last December via a logbook entry. The Ilec variometer was installed via a 337. If you'll email me you fax address I'll fax them to you.

my mechanic tells me, that an Equipment List showing the Dynon D10A as installed equipment would help in the 337 process.
Could you provide a copy of that?

I will pull together some materials this weekend to help.

Thread Title : Documents from N175XS
Here are some files that may help from my bird 200.175:
Aircraft Flight Manual (AFM): file (http://www.xopa.org/kb/kb_upload/file/N175XS-AFM.pdf)
Near the end of the document is the List of Equipment (LoE): file (http://www.xopa.org/kb/kb_upload/file/N175XS-LoE.pdf)
You can see pictures of the panel below (icons linked to the gallery). Note that I have a new slim panel configuration that the factory has been working on with the guys at Ximango USA.

Let me know if there is anything else I can provide to help with your installation. Note that the guys at Ximango USA may be able to help you with the default values and calibration values for the instruments.
