With Trans Canada Airlines / Air Canada February 1959 until withdrawn in October 1971, this Viscount was sold to United Aircraft of Canada in 1972. Modified to test the company's larger PT6-50 engine mounted on the nose , the aircraft tested other versions of the PT-6 between 1977 - 89. Donated to École nationale d'aérotechnique in Saint-Hubert, QC, it was used as an instructional airframe until loaned to Fondation Aérovision Québec in 1994. Moved by road to the Institut de Protection Contre les Incendies du Québec, it's used for fire and rescue training at the time of uploading. It still carries the faded remains of "Sphinx Air" titles which were applied in 1999 for use in a movie. On the other side it also has fake registration N6225C.

One of the last Viscounts to enter the Trans Canada Air Lines fleet has here been sold to a Calgary based travel club. Later it went to Pratt & Whitney of Canada as a flying test bed where it served for many years with various PT6 & PW100 engines installed in the nose.
