I read on ATSB site the exact same thing happened n a Virgin 737 into Adelaide on the 13th Sept 17.
If two crews from two seperate Airlines in this fairly small aviation community have seriously injured cabin crew as a result of a software change to the aircraft, will the ATSB find the reason the crews were not aware of the risks? The ball has obviously been dropped somewhere and the fact that seperate crews from seperate airlines have been caught out suggests that the mistake was made further up the food chain than operational crew.
Training Departments? Airline Ops management? CASA?
