Formerly T-01 and T-02 with the Fuerza Aerea Argentina, Austin Airways acquired C-GQWO in 1979. Austin was merged into Air Ontario in 1989 and this aircraft was sold to Air Creebec in March 1989. Converted to an unpressurized freighter in 1998, it hauled fuel to northern communities. The registration was cancelled in Feb 2012 after it the freighter was donated to the Canadian military for training.
