This was the prototype T400 Skyfarmer and was converted from an incomplete T300 model. It flew with the registration VH-TRX. This was Transavia's trade plate registration, not a formal registration, and could be transferred from aircraft to aircraft for test fights and demonstrations. As VH-TRX it performed in the Bicentennial Air Show at Richmond air force base in October 1988. In January 1989 it was finally entered in the register as VH-TZZ and in 1990 sold to Hazair in Albury, New South Wales. -TZZ was current in 2018 but in storage after being damaged.
