The latrst OEBs for A320F and A330/340 issued by Airbus are directly related to the Lufty incident. The incident appears to have been caused by two AOA probes producing similar but erroneous data and consequently the architecture disregarding the correct third one.
The answer to the problem is to turn off two ADR and force the aircraft into Alternate Law. The more serious question is why are AOA probes icing up in the first place?There are two types of probe I believe and it will be interesting to see which one was fitted to the Lufty aircraft.
