JetProp Commander (Model 840, 900, 980, 1000)

In 1979 Rockwell flew the Jetprop Commander 840 and 980, developments of the 690 powered by 625kW (840shp) Garrett TPE3315 and 730kW (980shp) TPE33110 turboprops respectively. These went into production with Gulfstream, who had purchased Rockwell's GA lines in 1979. The Jetprop 1000 was similar in overall dimensions but introduced a revised interior that made better use of the available space and the 980's engines. The Jetprop 900 meanwhile combined the revised interior with the 840's engines.

Unequivocally the hands down all around best performer in its class (and many others), the Commander JetProp series defines performance, efficiency, and value. As a second generation to the Turbo Commander series, the JetProp Commanders offer greater wing area along with a larger fuselage and cabin. Engine options extend up to the TPE 331 Dash 10T engine producing 1,000 shaft horsepower and speeds exceeding 300 knots while burning only 75 gallons of fuel per hour. The 1000 model JetProp Commander has seating for up to 9, including a lavatory and is certified to FL350. RVSM capability is available via STC. JetProp Commanders offer a long range cruise capability between 1,700 and 2,050 nautical miles.

When compared to major competing aircraft in its segment on numerous factors such as cabin volume, cruising speed, range, cruising altitude and climbing ability, the JetProp Twin Commanders have the highest overall average rankings of the group, exemplifying the well rounded nature of the aircraft.

The Rockwell Turbo Commander 695 (JetProp Commander Model, 980) later built by Gulfstream) was the final basic type of the Twin Commander series, with several variants. A slightly shorter fuselage (in comparison to the 690B) and more wingspan were the major visible features, as well as a differently shaped exaust pipe and nose mounted landing lights. Twin Commander Aircraft LLC did the upgrade to the JetProp 840, which basically consists of slightly more powerful engines, apart from a total overhaul of the structure and all systems. With a service ceiling of 34.100ft and a cruise speed of 290 kn TAS this aircraft has an outstanding performance within it's class. The take-off distance and stall speeds are lower than those of the 690B. This version comes with the enlarge fuel capacity option, which gives it a range of 2,040 NM / 3,776 KM.
