An EAD has just been released following an issue experienced by an A330 crew:
This only applies to the newer aircraft with the new AoA probe that is mounted on a raised area away from the skin.
I've heard of spurious stall warnings and have even experienced spurious stall ident and stick push at 500 ft in a much older 4-jet, I've taught 'incipient' stall recoveries and 'fully developed' stall recoveries, but never in 40 years have I ever heard of an 'undue' stall warning....
Considering every aircraft flying is at risk of undue stall warnings, I am surprised that you have not heard of it (sensor issue, radome damage, bird strike, ADC issue etc). An example would be the 777 incident out of Perth
