If you need legal IFR then you will probably need certified avionics, anywhere in Europe. That is certainly true for US Experimentals in the US.
It’s true that you may not need STC coverage for the installation though. That’s an interesting variation…
I always thought the bigger D.140 (Mousquetaire) was IFR certified, but a quick Google shows only a few were. An article says one (F-BOPS) took 9 months for the application to be approved by the DGAC. I was hoping for a precedent in France, but I doubt any D.120s were ever IFR. I assume the one you’re looking at is also factory-built by SAN, so originally certified and not homebuilt. It sounds like it will come down to what the LAA decide: do you know of a friendly inspector you can talk to?
Thanks all for the comments! lots to consider. I have reached out to a LAA inspector and the LAA. theres never been a IFR D120 on the laa register, but in theory it IS possible. (probably once the paperowk is heavier than the aircraft, as the saying goes).
Not wanting to drift this thread too far, but does anyone have details of a 2-axis autopilot installation in a Jodel D140E?
I found a wing-leveller fitted to G-JRME –
and fitting a pitch servo to operate the elevator horn looks fairly straightforward.
But it’s sometimes easier to copy/improve than to start with a blank page and there are many more Mousquetaires in France…

I searched “D140 Autopilot” and got a thread.
I copied it, but I’m not happy to paste it to EuroGA..
Thanks, I’ve applied to join…
Time to revive this thread. I have purchased a gns430 which i plan to fit and now conidering antenna locations.
problem number 1: the jodel featires an all moving vertical fin, ive only ever known vor antennas be mounted on the vertical fin. Where would it be best to place this antenna? The aicraft is a wooden frame so shoudnt cause too much intererance. was thinking on the rear rusulage. but above or below?
We had a VOR in G-AZAD, DR1050, but I don’t remember where the aerial was. I think it was underneath. That DR1050 was lost in 1999.
Our radio and Mode S aerials in G-AZWF were inside the rear fuselage. Both worked satisfactorily. The DR1050 has a large access hatch behind the rear seat and tank.
VOR is receive only, so distance from occupants doesn’t matter.
