Well that leaves a lot of evidence to back up the "inadequate" statement behind, and does not portray amy perspective as to how severe inadequate is.
Clearly this was not just an oops then, it was systemic, and even more reason the company were lacking, and without company surveillance what chance did CASA surveillance have.
This stuff is an all in effort, and even if CASA were perfect, the systems the company and pilots were following was never going to leave even the most proactive CASA folk anything to work with by the sound of it.
Bit like a dog chasing its tail.
