I was looking into this matter tonight. And I found on this page that Airbus claims it only happened two times ever.

Whereas this is clearly false.
There is this case for example where the AOA protection malfunctionned :

(prevented a go around that was required)
I also know from primary data that this happened at least two or three times in another european airline (this time with the same freeze as the Lufthansa 321).
The article in the first post says it happened several times at lufthansa as well.
So, why is airbus making such unsupported claims ?
