The MD-11 has a "FADEC BAR" that to my knowledge will spool beyond max rated by slamming the throttles to the firewall removing protection.
I have had several flights overloaded that resulted in fuel deversion for uplift, one was an 8 hr flight and was told we were as heavy as 20k lbs overweight. This fine beast will still climb out nicely overloaded. Have had a DC-10 auto rotate due to an aft CG.
There is a good chance that there was a combination of being heavy with an aft CG. There is also a good chance of a cargo shift EG
Arrow/KMIA).
Given the ZFW possible incorrect entry there is also a possibility that T/O flap and trim settings were not correct.
