BOAC...
Air Accidents Investigation: Airbus A330 C-GGWD and Airbus A340 TC-JDN
Read it carefully. I doubt if there is a relationship between the two behaviours of the aircraft but take a look for yourself and see what you think. The report focuses on a TCAS and AIRPROX event and I don't think does a credible job of explaining the pitch up.
The summary of the behaviour of the A340 in the "zoom-climb" claims that in the overspeed and turbulence, that the AFS reverted to the Alpha Protection Law. From my research, that was changed before this event occurred to inhibit the AoA Protection Law above M0.53. The other frustrating aspect is, the recorder data that is included with the report does not have AoA...the very parameter claimed to have caused the triggering of the AoA Prot Law and the cause of the zoom-climb.
Anyway...these things are complicated. Maybe I'm mis-reading it all.
