It's funny because I know a guy Who's had a Dynon D10a installed in a Mooney for about 8 years.  Flies it IFR all the time.  Never an issue. 

How did he do it? Field approval?  Or renegade?

Back in 2008 or 09 he did it as a minor alteration.  Later, October 2010 the FAA came out with the AC that said no EFIS in certified airplanes.  The same AC that also slipped in the sentence about no HID landing lights without an STC as well.

Does that means he needs to remove it - or is it grandfathered?

Sometimes it really makes you wonder where these silly AC come from.  No EFIS?!  No HID?!  I wonder what bug got under someone's butt to put that one out.  Or was it a lobby from the certified avionics side?

Dynon also has a "portable" EFIS -the D1 D2 units that are certainly not Primary for anything, but they would work just fine in an emergency. They run on their own batteries and are not connected to the pitot static system. Everything is GPS derived. I had one for a while, and it always functioned perfectly. It is now in the panel of a friend's Mooney in a legal "snap-in" mounting. It may be a while before there will be a STC for Dynon products to be installed in Mooneys, and the D1/D2 units are easy to mount, and could prove very valuable in case of a vacuum failure, or an electrical failure.

I gave mine away because I want my friends to have a backup AI, and I can use FlightSteam with my iPad Mini 4 and Foreflight to have an EFIS on the pilot side yoke. Works well, including SV with the interface with the GTN 750.

I also have a Mid-Continent "Lifesaver" electrical AI with its own battery as the primary backup to the vacuum AI. If Bendix/King/Honeywell ever actually sells their new replacement electrical AI (with autopilot support), I will get rid of the vacuum system, including the electrical back-up pump in the tail cone. That would save some weight.

Where does it say that your attitude indicator needs to be TSO for non-commercial operations?  Lots of instruments and radios in my 1966 vintage airframe don't aren't TSO.  Count the KX-170s in the world.  Is this all a matter of manufacturers and retailers saying "for experimental use only" so it's not on them in an attempt to limit liability?  I'm not an IA, so I don't have years of scars from dealing with the feds, but if replacing an instrument is minor, and TSO isn't required for Part 91 operation, then isn't sticking any sort of "gyro" in your panel up to you?  Particularly if it's redundant?

The FAA never makes mistakes

I would guess that he got to keep it. Once you get that 337 field approval, you're gold. Talk about being in the right place at the right time.

I've traveled to a lot of third world where you can often bribe government officials to get things done/approved. If I could get away with bribing an FAA maintenance inspector to approve a 337 for a Dynon SkyView I'd probably do it.

If the TSO'd units are so thoroughly tested prior to approval and installation why do they require regular software updates?

In my experience with the SkyView units most of the software updates were to add features like SV, or their own autopilot interfaces. As I recall, the mapping databases were free. I had very early units but never felt left back as features were added to the newest boxes.

Adding to my last response, I think the FAA wanted a more consistent process for granting field approvals in order to minimize FSDO shopping. Unfortunately this had the effect of the belt being tightened and not loosened for FAs.

I suspect it was a good time to get sh** done on your plane before that AC was released. I doubt the FAA has any interest in reviewing every single field approval granted to determine which ones would be revoked. Those who were lucky enough to get an FA during that time are pretty much home free.

No, Los Angeles.
