Gentlemen, I do not hold any brief for CASA and their neglect of proper procedure and accountability was severely lacking in this case. However, they did not cause the crash.
They were not flying the aircraft on that day.
They were not doing an approach for which only one of the crew were certified.
They were not conducting the approach in a totally cowboy manner with excessive airspeed and dropping below the minimum sector altitude.
Had CASA performed as required in this case it would have undoubtedly saved a plane load of innocent people from being killed but also would have caused many here to rant and rave about how they had unfairly dealt with a good bloke who had given many a start in aviation. A man who removed himself from the gene pool by similar idiot behaviour at the controls of an aircraft and unfortunately took others including a very well respected PRuNer with him, Think of the postings in relation to Airtex if you want an example of what happens when a cowboy gets dealt with by CASA.
You can argue until your blue in the face about the design of the GPS approach but if it had been flown as designed with an appropriately endorsed multi-crew with the pilot monitoring calling out the sector altitudes the crash would not have happened. It was a cowboy who killed those people and company's who operate in that fashion should be the target of our anger.
