Aircraft overview

The Beechcraft Duke 60 is a pressurized, piston twin produced by Beech Aircraft as the Model 60 Duke. It first flew in 1966, entered production for the 1968 model year, and the Duke line continued through 1983. The original Duke 60 established the type before the later A60 and B60 refinements. It occupies a distinctive position among used aircraft: a cabin class, pressurized piston twin with Beechcraft handling and build quality, intended for owner pilots and small business operators that wanted turbine like altitude capability without moving into a turboprop.

Performance & specifications

The Duke 60 is powered by two turbocharged Lycoming TIO-541 engines, rated at 380 hp each. Typical cruise performance is commonly reported around 220 to 230 knots, depending on altitude, power setting and engine installation. The aircraft was certified with a service ceiling of 30,000 feet, one of the key reasons for its appeal among piston twins. Published range figures vary with reserves and configuration, but long range planning is typically in the high hundreds of nautical miles rather than light twin short hop territory. Useful load depends heavily on equipment, paint, interior and modifications, so individual weight and balance records matter more than brochure figures.

Cabin & avionics

The Duke 60 normally seats up to six, with two cockpit seats and a four place cabin. The pressurized cabin is the aircraft’s defining comfort feature, allowing weather avoidance and higher altitude cruise without oxygen use in normal operations. Cabin access, baggage space and seating comfort are good for the class, though the Duke is not a stand up cabin aircraft. Original avionics were conventional analog equipment, typically BendixKing, Collins or similar period radios and autopilots. Many used examples now have Garmin GNS or GTN navigators, Garmin G500 or G600 displays, Aspen electronic flight displays, engine monitors and updated transponders. Garmin Perspective and factory G1000 installations are not native Duke 60 equipment.

Buying & value

Prospective buyers should separate the original Duke 60 from later A60 and B60 aircraft, as systems, details and market values can differ. Key inspection points include engine history, turbocharger condition, pressurization integrity, exhaust system condition, corrosion, landing gear rigging, deice equipment and the quality of avionics or engine modifications. Some aircraft have aftermarket performance or engine upgrades, while others remain close to factory configuration. On the used market, the Duke 60 is usually positioned below comparable turboprops but above many unpressurized piston twins in complexity and operating cost. Current PlaneFox listing data shows an average asking price around EUR 203,000, with observed asking prices from EUR 129,000 to EUR 340,000.
