With reference to the central control column on the Airtourer, AESL did not replace "it" and sell them back to the Australians, you are obviously thinking of the CT4B that already had 2 control columns that AESL supplied to the then British Aerospace-Ansett Flying College at Tamworth NSW in the early 1990's. Extra refurbished ex RNZAF CT4's were supplied to the College in the late 90's as more had become required for the military training contract
