To be fair to CASA, regulators anywhere would want to know what an Airline's SMS does in circumstances like this. If the answer from Airline Management the following Monday when the inquiry came from the Regulator was " Yeah he came close to losing it but he caught it in time so we let him continue" would not be received well. Stand down would be expected by the regulator with an investigation to follow. If it was a case of flouting SOPs by showing Flapless approaches to trainees in the aircraft then it would be Just Culture time I would say.
Agree with the Safety department comment though. They have not got a good rep in house.
