If you fly a French aircraft the ADs are listed here.
www.gsac.fr
Look initially under emergency ADs (CNs)
Then under manufacturer of the aircraft eg. Apex and then the manufacturers of engines and equipment eg. Limbach, MT propeller, Becker avionics, Jolliet ELTs, etc.
The website is easy to use and has an English language section if the French is difficult.
