Aagh yes good ol CASA. This case is an example of their take on 'just culture'.
There is a thing called 'leading by example'. CASA actions merely destroy any desire or will within industry to follow their example, uphold honesty and integrity or even report an issue where relevant.
When you have a regulator hell bent on bullying the industry and driving a pineapple through the industry's a#s for personal retaliatory reasons this is the system you end up with.
Metaphorically speaking the entire regulatory structure needs a tin of Avgas and a match set too it and we need to start again, the rot is too well entrenched, the cancer cannot be cured.
