LeadSled you are incorrect regarding AFM compliance and changes. An operator has every right to vary their SOPs in line with their operations as is stated at the very front of the Airbus FCOM, these are only recommended procedures and may be tailored for operations variances. The go around procedures was a complete breakdown in the SMS.
In saying that, I know for a fact that Jetstar is leaning towards its operation being 100% aligned with FCOM.
As for the incident, completely a symptom of a failure in training. As the organisation moves towards cadets, this is when they should be spending more money on training and training facilities.
If CASA want to make a difference they would regulate training facilities access for all aircrew.
