Of course my dear Grey,
such as SAAB-Fairchild SF440,but no more details are known,and may be developed from SF340.
From Aviation magazine 15-6-1985,
A logical situation for an aircraft that was the first on this new market in
June 1984. However, it is not for lack of commercial dynamism proven by
a noted offensive on the Australian continent. For its part, in the field of
projects, Saab-Fairchild presents an enlarged version of its basic 35-seat
commuter, designated SF-440.
Planned for 42 to 44 passengers, this new model with an elongated wing
and fuselage,should be powered by General Electric CT7-9s of the 2,000 hp
class.
"Should be", because no launch decision seems likely to be taken before
the end of this year, although the existence of this project was announced
several months ago already.
