Seeking Answers,
I would like to put forward the following.
It was a CFIT, it happened because Company SOP's were not complied with.
The Company was also at fault having prior knowledge that these SOP,s were being disregarded.
NZCAA is also at fault for not ensuring that their regulatory requirements to carry out these flight to the Antarctica were being complied with.
An inspector from CAA was in fact scheduled to travel on the Accident flight, however a family illness prevented this, if he had of been on the flight would the Company and NZCAA requirements have been so flagrantly disregarded??? who knows, and who will ever know.
The CVR is not really that important in showing the cause of the accident, it is of interest only in trying to explain why they did what they did.
