The following may perhaps be of interest.
In the summer of 1973, General Aircraft negotiated with unidentified Canadian interests to start production in Vancouver, British Columbia, of a twin-engine version of the GAC-100 commuterliner. These Canadian interests would control the company which was to do the work.
The GAC-100 actually saw the light of day in 1968. It was then a four-engine aircraft designed by General Aircraft with the help of another American company, Aircraft Engineering. An Australian state-owned company, the Government Aircraft Factory, participated in that production project. In the fall of 1969, Pacific Airmotive agreed to manufacture the GAC-100 in its shops. This agreement was canceled in the spring of 1970 when the parent company of the small American company, detergent maker Purex, decided to give up aviation. Suddenly, General Aircraft was forced to put the GAC-100 on the back burner. The aircraft resurfaced in the late summer of 1972 when the U.S. Civil Aeronautics Board increased the maximum permissible weight of commuterliners usable in the United States.
This increase explained the Canadian factory project mentioned above. The discussions concerning it did not yield any results, however. General Aircraft became Commuter Aircraft around 1980-81. The CAC-100, a four-engine aircraft capable of carrying up to sixty passengers, was abandoned around 1985 even before the construction of a prototype
