The turboprop fueled improvements of the Aero Commander group of light twins appreciated a two decade long creation run, and were manufactured by three organizations before generation stopped.
The first Turboprop Commander was focused around the 680flp, and first flew on December 31 1964, however rather than cylinder motors force was supplied by 450kw (605shp) Garrett Airesearch Tpe331 turboprops. This introductory Turbo Commander model was assigned the 680t and entered generation in 1965.
Dynamically enhanced improvements of the essential Turbo Commander seemed, including the 680v, which presented an expanded most extreme takeoff weight, and the 680w with enhanced motors. Emulating North American Rockwell's takeover of Aero Commander and the presentation of the further enhanced Model 681, the name Hawk Commander was received for a period, however it was dropped from 1971 with the arrival of the 681b.
When of the presentation of the 681b, Rockwell was at that point flight testing the overhauled Turbo Commander 690, which first flew on March 3 1968 and was certificated in July 1971. Rockwell presented the enhanced 690a before long.
In 1979 Rockwell flew the Jetprop Commander 840 and 980, improvements of the 690 controlled by 625kw (840shp) Garrett Tpe3315 and 730kw (980shp) Tpe33110 turboprops individually. These went into generation with Gulfstream, who had obtained Rockwell's GA lines in 1979. The Jetprop 1000 was comparative in general measurements however presented an updated inside that brought about a significant improvement utilization of the accessible space and the 980's motors. The Jetprop 900 in the interim joined the updated inside with the 840's motors.
