What the guy describes is basic bad stall behaviour whereby the A310 raises its nose when approaching a stall and flies itself deeper into a stall.
Somebody's going to have to be a lot more specific before this rumour is taken seriously..
Under what configuration, trim, a/s and MNo did the suggested behaviour manifest?
Then we might be able to establish how relevant it is to this thread,
if it is a correct & thoroughly objective assertion.
