They would have stalled the A330 in all configurations of gear, flaps and cg in flight test back in 1994. How serious was the damage to the plane in the aft cg stalls?
A full stall series in a DC10, for example, will damage the ailerons and can tear the elevator counterweight horns right off.
For training or refresher, wiki has a fair description of spins and flat spins. The 65 to 90 degrees angle of attack of a flat spin is awfully similar to the BEA report of AF447.
