The perils of a warts and all investigation
Oleo is correct, the names of the CASA members on the investigation and special audit team are freely available. A look at the list of inspectors shows that as well as the usual flying ops and airworthiness inspectors there was one of the relatively new breed of Safety Systems Inspectors. Their task is not only to look at the effectiveness of the systems that should have plugged the holes in the cheese and not only the systems of the operator but also the regulatory systems that should have plugged the holes.
Rumour has it that the latter were raised particularly in relation to the fatigue risk management system that CASA had previously approved. Being the devil's advocate and highlighting deficiencies in your employer is fraught with danger but that is the lot of a proper investigation and apparently the inspector concerned was given a pineapple previously for, when asked to examine CASA's responses to ATSB safety recommendations from the Lockhart River accident, he did not hold back on criticising those responses ( or lack of them). Admittedly the pineapple was purported to have been launched not from the person that requested the report but from the person who attracted the criticism. Or so I hear.
