Seems to be the story. Talking to a capt, who had spoken to a capt......(you know how it goes) they were going round from a cat3B check (reason unknown) but had not hit the TOGA switches, instead pushing the throttles up manually and pulling back on the stick with the AP still engaged. The amount of force applied eventually caused the AP to disconnect and then the a/c over-rotated causing the tail to impact. The a/c climbed out, flew a circuit and landed uneventfully. Apparently damage sustained was enough to be classified an aircraft "accident" by the NTSB. The FCC's were checked on the a/c with no faults found or previously recorded and have now been removed for bench-check. (This is the only FACT i know) Again, this is just what i heard and cannot be classed as actual. The truth will unfold eventually.
