The Ansett B767 is an interesting story which I was purely an observer as our Association struggled. So after reading the various opinions on this I went to the history books, specifically the Purple Stripe produced by the AAFEA when they were winding up the Association .
According to that book, and as has been stated earlier, the B767 was originally produced in 3 versions including "hard wired three crew,new technology 2 crew and a 3 crew version that would allow conversion at a later date. It also says that the aircraft used for certification were 3 crew aircraft and the first 30 aircraft were built as 3 crew. All 30 were then converted to 2 crew but he Ansett aircraft were then converted to the 3 crew soft wiring to allow change at a later date.
