Gulfstream American Commander Divi¬sion announced it will build a lower-¬powered version of its large cabin 1000 model. The new airplane will be called the Commander 900. By moving the floor and the pressure bulkhead and by chang¬ing the windows, Gulfstream has been able to come up with a great deal more cabin space inside the old Commander fu¬selage.
First built in 1982.
