Aircraft overview

The Commander 690 Turbo Commander is a pressurized, twin engine turboprop business aircraft developed from the Aero Commander piston twin line and produced under the Rockwell Commander name. The 690 series entered the market in the early 1970s, with production of the core 690 family running through the decade before later 690A and 690B developments carried the line forward. It matters in the used aircraft market because it combines turboprop speed, a high wing layout, rugged systems and a relatively compact cabin class footprint. For buyers comparing older twin turboprops, the Commander 690 Turbo Commander is often evaluated against aircraft such as the Beechcraft King Air 90 series and early Cessna Conquest models.

Performance & specifications

The Commander 690 Turbo Commander is powered by two Garrett AiResearch TPE331 series turboprop engines, typically TPE331 dash 5 variants rated in the 700 shp class. Typical cruise performance is commonly reported in the high 260 to low 280 knot range, depending on altitude, weight, engine condition and installed modifications. Usable range is commonly around 1,000 nautical miles or more with reserves, again dependent on payload and operating profile. The aircraft has a maximum certified ceiling of about 31,000 feet. Useful load varies by individual airframe, equipment and modifications, so current weight and balance records are important when comparing examples.

Cabin & avionics

The cabin is pressurized and typically arranged for six to eight occupants, including pilots, with club seating or mixed executive layouts in the passenger area. The high wing and large cabin windows give good visibility, while the relatively narrow fuselage reflects the aircraft’s 1960s design origins. Baggage capacity and cabin finish vary significantly because many aircraft have been refurbished. Original avionics were analog and electromechanical. On today’s market, typical panels range from legacy Collins, Bendix King or mixed installations to upgraded Garmin configurations, often including GTN navigators, GNS units, modern transponders, ADS-B equipment and glass retrofit displays such as Garmin G500 or G600 series systems. Garmin Perspective and factory G1000 were not original Commander 690 installations.

Buying & value

Prospective buyers should review engine times, hot section and overhaul status, propeller times, pressurization performance, corrosion inspections, landing gear rigging, fuel system condition and compliance with applicable service bulletins. Logs should clearly document modifications, avionics changes and any engine program participation. Common value drivers include upgraded interiors, modern avionics, known maintenance history, paint condition and TPE331 support status. Related 690A and 690B aircraft may appear in comparisons, but they are distinct developments, so specifications should be checked by serial number. Current PlaneFox used market data for Commander 690 Turbo Commander listings shows an average asking price around EUR 1,010,000, with observed listings from about EUR 568,000 to EUR 1,960,000.
