How to Buy a Beechcraft Duke B60: Buyer's Guide
A fast, pressurized, turbocharged piston twin with ramp presence. It rewards a well-funded, disciplined owner and punishes deferred maintenance.
Updated October 2026 · Market data from 8 live fyiAero listings, the FAA registry and NTSB records
Overview
The Beechcraft Duke is a six-seat, pressurized, turbocharged piston twin that Beech built from the late 1960s into the early 1980s. It slotted between the Baron and the Queen Air and King Air line. Two turbocharged Lycoming TIO-541 engines turning three-blade props give it performance that still impresses: fyiAero's operating estimate puts cruise around 233 knots with roughly 1,010 nm of range. With its swept tail, long nose and airstair door, it remains one of the best-looking piston twins ever built.
It is also a complex, aging airplane with a small fleet. The FAA registry shows 184 Duke-family aircraft in the U.S., and fyiAero listings currently show 8 for sale, all B60 models. Asking prices run from $129,000 to $290,000, with a median of $147,461. That purchase price is modest for what you get. Running costs and big-ticket items like engines, pressurization and landing gear are not modest.
The right Duke is one that has been flown regularly and maintained by a shop that knows the type. The wrong one is a bargain that has been sitting, and it can cost more than the purchase price to bring back. Shop the logbooks and the engines first and the paint and avionics second.
Who it's for. The Duke suits an owner-pilot who regularly flies 300 to 900 nm trips with family or business passengers and wants to get above the weather in pressurized comfort, without paying turbine prices. This is not a step-up airplane for a low-time pilot. Underwriters will want to see a solid multi-engine and instrument background, meaningful time in high-performance or pressurized aircraft, and formal type-specific initial and recurrent training. Pilots without that experience should expect high premiums, required instruction with a Duke-experienced instructor, or difficulty finding coverage at all. Budget for annual recurrent training; with a small fleet, finding an experienced instructor and a knowledgeable shop takes some planning.
Generations and variants
| Version | Years | What changed |
|---|---|---|
| Model 60 Duke | 1968-1970 | The original Duke established the layout: pressurized cabin, turbocharged TIO-541 engines and the airstair door. Few of these come up for sale, and early turbo and pressurization hardware makes condition and documentation especially important to price. |
| A60 Duke | 1970-1974 | Beech refined the turbocharging system and made other improvements over the original. These trade below B60s when you find them, but you should judge them on engine time and systems condition rather than model letter. |
| B60 Duke | 1974-1982 | The final and most common version, with an updated interior and further system refinements. Every Duke currently listed on fyiAero is a B60, so this is the market most buyers are actually shopping. |
| Turbine-converted Duke | Aftermarket | Some Dukes have been converted to Pratt & Whitney PT6 turboprop power under an STC. This changes the economics, performance and price dramatically, so value these as a separate market from piston Dukes. |
What a Beechcraft Duke B60 costs to buy
6 priced listings on fyiAero right now ask between $129,000 and $290,000, with a median of $147,461 and a median of 3,480 hours total time. Against fyiEstimate, 4 are priced below estimate, 0 within range and 2 above.
- fyiAero listings show asking prices from $129,000 to $290,000 with a median of $147,461. That is a wide spread for a fleet this small, and most of it comes down to engine time, avionics and maintenance history.
- Model year is a weak price signal. In fyiAero's sample, 1976 Dukes averaged $147,461, 1979s averaged $214,950 and 1980s averaged $159,450. Do not pay a premium for a later year unless the engines and systems back it up.
- The median listed airframe is around 3,480 hours. Dukes in the 3,000-5,000 hour band show a median ask of $189,900, so moderate airframe time is normal and not a dealbreaker. Engine time and calendar time since overhaul matter far more.
- Price the engines first. A Duke with two run-out or long-idle TIO-541s is worth substantially less than its asking price suggests, because overhauls on these engines are expensive and turbocharged components add to the bill.
- With only 8 aircraft for sale nationally, be prepared to travel for the right airplane. Use an independent pre-buy shop with real Duke experience, not the seller's shop.
- fyiAero's estimate shows an average pre-owned value around $221,900, above the current listing median. Well-equipped, well-documented examples command a clear premium, and tired ones sit.

Pre-buy inspection checklist
Have a shop that knows the type do the pre-buy, and ask them to research every applicable AD and service bulletin. Pay particular attention to:
- TIO-541 engines: compressions, borescope and oil analysis. These are expensive engines to overhaul, and parts support is not what it is for common Lycomings. Borescope the cylinders, review oil analysis trends, and confirm time and calendar time since overhaul for both engines.
- Turbochargers, wastegates and controllers. The turbo system is a frequent source of squawks and cost. Check for oil leaks, exhaust leaks, wastegate operation and the ability to make rated manifold pressure without overboost.
- Exhaust system and heat shields. Cracked exhaust components on turbocharged engines create fire and carbon monoxide risks. Inspect every slip joint, clamp and weld closely.
- Pressurization system and cabin leak-down. Outflow and safety valves, door seals and controllers all age. A pressurization test confirms the airplane will hold cabin differential, and fixing leaks can be labor-intensive.
- Landing gear actuation, gearbox and rigging. The retractable gear system needs proper rigging, lubrication and inspection of wear points. Have the shop do a full gear swing on jacks and review its overhaul history.
- Wing structure, spar areas and corrosion. Most Dukes are 40-plus years old. Look carefully for corrosion in the wings, spar areas, belly and gear wells, especially on airplanes based near salt water or kept outdoors.
- Fuel cells, lines and fuel system. Aging fuel cells and seals can leak or deteriorate. Look for staining, fuel odor and evidence of past repairs, and verify that all tanks and crossfeed operate correctly.
- Combustion cabin heater. Gas-fired cabin heaters need regular inspection and pressure testing for safety. Confirm the heater is compliant and has documented inspections.
- Propellers, governors and de-ice equipment. Check prop overhaul status, governor and feathering function, and the condition of boots and prop de-ice. Have the shop research all applicable propeller and engine ADs.
- Logbooks, AD compliance and damage history. A complete, continuous maintenance history is worth real money on a Duke. Have the shop research every applicable AD and service bulletin and look for any undocumented damage repairs.
Popular upgrades
- Modern panel (Garmin glass PFD/MFD and GPS navigator). A current IFR panel with WAAS GPS and ADS-B is one of the biggest value drivers. Original-panel airplanes trade at a noticeable discount, since buyers price in the cost of a retrofit.
- Digital engine monitor. A multi-probe engine analyzer is close to essential for managing turbocharged engines. It adds value and helps protect two expensive powerplants.
- Updated or modern autopilot. A reliable, well-maintained autopilot matters in a high-workload, single-pilot pressurized twin. A newer STC'd system raises appeal, while a tired original autopilot is a negotiating point.
- Fresh interior, windows and LED lighting. Dukes are bought partly on comfort and looks. A refreshed cabin, uncrazed windows and LED lighting help resale but will not offset weak engines.
- Turbine conversion. PT6-converted Dukes are a different airplane in performance, reliability and price. They sell well above piston examples and should be valued separately.
Ownership costs
fyiAero's operating estimate puts variable cost at about $325 per flight hour, with fuel burn around 41.2 gallons per hour at a 233-knot cruise, or roughly $1.39 per nautical mile. The estimate's annual budget is about $38,281 for 69 hours of flying. Treat that as a baseline, not a ceiling. On a Duke, the costs that hurt are engine overhauls on two turbocharged TIO-541s, turbo and exhaust work, pressurization repairs, landing gear overhaul and avionics modernization, and any one of these can run well into five figures. Insurance will be significant, especially for pilots new to type. Hangar storage is strongly recommended to protect the airframe and interior. A sensible rule is to keep a healthy cash reserve beyond the purchase price, because the cheapest Dukes are often the most expensive to own.
Safety record
NTSB records show 6 accidents involving the U.S. Duke fleet over the last 10 years, 3 of them fatal and 3 with the aircraft destroyed. Against a registered fleet of 184, that works out to about 32.6 accidents and 16.3 fatal accidents per 1,000 aircraft over the decade. With a fleet this small, a handful of events moves the rate a lot, so read it as a reminder of the airplane's demands rather than a verdict on its design. The Duke is fast, heavy and complex. The risk areas are the classic ones for high-performance piston twins: engine failure on takeoff or go-around, fuel management mistakes, turbocharger and engine-management errors, and pilots who do not fly enough to stay current. Regular type-specific recurrent training with real engine-out practice, disciplined systems management and conservative personal minimums address most of that risk.
Alternatives to consider
- Beechcraft Baron 58P. This is Beech's other pressurized piston twin, with more common Continental engines and broader parts and shop support. It is somewhat slower and less roomy, and lacks the Duke's presence.
- Cessna 340A. It is a pressurized six-seater with a larger fleet and plenty of maintenance knowledge in the field. Performance is similar or a bit less, and it is generally easier to support.
- Piper Aerostar 601P/602P. It is faster and more efficient than a Duke, but the cabin is tighter. It has a strong owner community but demands similar pilot skill and maintenance discipline.
- Cessna 414 / 414A. It offers a bigger cabin and more useful load for family or business hauling. It is slower than a Duke, but the fleet and support network are larger.
- Turbine-converted Duke or early King Air. This route trades a much higher purchase price for turbine reliability and simpler engine management. Consider it if your budget can stretch and you fly enough hours to justify it.
