How to Buy a Piper PA-23 Aztec / Turbo Aztec: Buyer's Guide
A rugged, roomy six-seat piston twin that hauls real loads into short strips, if you buy one with honest logs and a clean spar.
Updated October 2026 · Market data from 13 live fyiAero listings, the FAA registry and NTSB records
Overview
The Piper PA-23 family began in the 1950s as the four-seat Apache. In 1960 it grew into the Aztec, which used 250-horsepower Lycoming six-cylinder engines, a bigger cabin and eventually a long nose with a baggage compartment. Piper built Aztecs until the early 1980s. Over that run the airplane collected a reputation as the pickup truck of light twins. It is slow next to a Baron, but it is stable and forgiving on short, rough strips. It also carries a load that makes it popular with freight haulers, survey operators, bush flyers and families who fill every seat.
Today's market is almost entirely Aztecs, normally aspirated and turbocharged. fyiAero listings currently show 13 PA-23s for sale, spanning model years 1963 to 1978. Asking prices run from $75,000 to $395,000, with a median of $184,900 and a median airframe time of 4,907 hours. The FAA registry counts 1,302 PA-23s in the U.S. fleet, so parts support and mechanics who know the type are still easy to find.
Nearly every Aztec for sale is 45 or more years old, so you are buying the airplane's maintenance history more than its model year. Spar and tail condition, engine time, heater compliance and avionics matter far more than whether it says C, E or F on the data plate.
Who it's for. The Aztec suits a pilot who needs to move people or cargo, often out of short or unimproved fields, and cares more about load and stability than outright speed. It is a common choice for a first twin because it is docile, has benign stall behavior and is stable on instruments. Its relatively low engine-out minimum control speed for its size also helps. It is still a twin, though, and the insurance market treats it that way. A low-time pilot with a fresh multi-engine rating should expect a meaningful premium. Expect a requirement for formal transition training, and possibly a stretch of dual time with an experienced Aztec instructor before solo coverage kicks in. Pilots with a few hundred hours of multi time and an instrument rating will see much better terms. Turbo models usually draw slightly higher premiums and more scrutiny.
Generations and variants
| Version | Years | What changed |
|---|---|---|
| PA-23 Apache (150/160) and Apache 235 | 1954-1965 | The four-to-five-seat ancestor with smaller Lycoming four-cylinder engines and, on the 235, the Aztec-style swept tail. These are rarely seen for sale and trade as economical training twins well below Aztec prices. |
| Aztec (original) and Aztec B | 1960-1963 | These introduced the 250 hp carbureted O-540 and the five-seat cabin, and the B added a longer nose with a baggage compartment and sixth-seat capability. They are the cheapest Aztecs, and the low end of current listings is dominated by early-1960s airplanes. |
| Aztec C and Turbo Aztec C | 1964-1968 | Fuel-injected IO-540 engines, redesigned longer nacelles and an optional factory turbo made the C a big step forward. Fuel injection and improved nacelles put these a notch above the early carbureted airplanes in value. |
| Aztec D and Turbo Aztec D | 1969-1970 | Panel and systems refinements over the C, including an improved instrument layout and interior. They are priced much like a well-kept C, and condition drives the difference. |
| Aztec E and Turbo Aztec E | 1971-1975 | The longer pointed nose added baggage room and a cleaner look, along with more modern panels. A well-equipped E is a strong middle-market buy. |
| Aztec F and Turbo Aztec F | 1976-1981 | The final version added a flap and stabilator interconnect for smaller trim changes, cambered wingtips and fuel and systems improvements. F models command the top of the market, and late-1970s listings show the highest averages. |
What a Piper PA-23 Aztec / Turbo Aztec costs to buy
13 priced listings on fyiAero right now ask between $75,000 and $395,000, with a median of $184,900 and a median of 4,907 hours total time. Against fyiEstimate, 3 are priced below estimate, 0 within range and 2 above.
- Know the spread before you shop: fyiAero listings range from $75,000 to $395,000 with a $184,900 median. The 1964 examples average $87,500, while 1977 airplanes average about $259,700 across three listings.
- Year is not destiny. A 1976 listing is asking $129,000, well below earlier 1969 to 1971 airplanes near $185,000 to $199,000. Engine time, avionics and paperwork move the price more than the model letter.
- Do not over-discount high airframe time. Listings with 3,000 to 5,000 hours show a $154,000 median and those over 5,000 hours a $162,400 median, because the market prices engines, panel and corrosion history over total time.
- Price both engines and both props separately. Two mid-time or run-out IO-540s, especially turbocharged ones, can swing the real cost of an airplane by tens of thousands of dollars. Ask for engine overhaul invoices, not just log entries.
- With only 13 airplanes listed nationally, good ones sell quickly. Have your pre-buy shop and insurance quote lined up before you call on a promising airplane.
- Decide on turbo or normally aspirated up front. Turbos earn their keep for high-altitude airports and flying over weather but add maintenance, while normally aspirated airplanes are simpler and cheaper to keep.

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:
- Wing main spar, spar caps and carry-through. Corrosion and cracking in the spar area are the biggest structural concerns on an aging Aztec. The shop should research applicable ADs and SBs and inspect through every available access panel.
- Stabilator, attach fittings and tail cone. The all-moving stabilator and its hinge and horn area have a history of cracking and corrosion findings. Freeplay, cable tension and fitting condition need a close look.
- Janitrol combustion heater. The gasoline-fired cabin heater is subject to recurring inspection and pressure-decay testing. A neglected heater is a carbon monoxide and fire risk, so confirm compliance and look for a CO detector.
- Hydraulic landing gear and emergency extension. The engine-driven hydraulic gear system, actuators, hoses and the emergency CO2 blowdown system must be inspected and tested. Gear-up and gear-collapse events are a known theme in the accident record.
- Engines, compressions, borescope and oil analysis. Check both IO-540s for time since overhaul, calendar age and cylinder condition, with trend oil analysis if available. Long-idle engines may be corroded inside even if hours are low.
- Turbochargers, wastegates and exhaust system (turbo models). Exhaust cracks, slip-joint leaks and turbo bearing wear are common and expensive. Inspect closely for heat damage in the nacelles.
- Fuel tanks, bladders, selectors and crossfeed. Aging bladder cells can crack and leak, and fuel selector valves wear. Verify that every tank and the crossfeed function correctly, since fuel mismanagement is a recurring twin-engine accident cause.
- Propellers and governors. Confirm overhaul status, applicable ADs and feathering function on both props. A prop that will not feather turns an engine failure into an emergency.
- Corrosion in nose baggage, battery box and belly. Battery acid, trapped moisture and fluids collect in these areas. Belly skins and nose compartment structure deserve careful inspection.
- Logbook continuity and damage history. Gaps, old repairs and freight or survey use with heavy cycles all affect value and future maintenance. Pull the FAA records and compare them against the logs.
Popular upgrades
- Modern GPS navigator and digital instruments. A WAAS GPS, ADS-B Out and electronic attitude or HSI displays are the single biggest value adders. Airplanes with original panels sell at a clear discount.
- Digital autopilot or upgraded legacy autopilot. A reliable, GPS-coupled autopilot greatly reduces single-pilot IFR workload in a twin and is a strong selling point. A worn-out original autopilot is often a liability.
- Dual engine monitor. All-cylinder EGT and CHT monitoring helps manage turbo and cylinder temperatures. Buyers expect it, and it adds modest value.
- Vortex generators or STOL modifications. Aftermarket VG and STOL kits can lower stall and minimum control speeds and improve short-field performance. They add value for backcountry and safety-minded buyers.
- Fresh engines and overhauled props. Not a modification, but matched low-time engines are the most powerful price driver in this market. They often justify an asking price well above median.
- LED lighting, interior and paint refresh. These improve reliability and curb appeal. They help an airplane sell faster but rarely return their full cost.
Ownership costs
An Aztec is an honest twin to operate. It burns about twice the fuel of a single, and you maintain two of everything. fyiAero's operating estimate puts variable cost at about $215 per hour, based on roughly 27.2 gallons per hour, a 178-knot cruise and a 770 nm range, which works out to about $1.21 per nautical mile. Flying 90 hours a year, the estimated annual budget is about $30,956, against an average pre-owned value near $121,204 in that same estimate. Beyond that, budget for engine and prop overhaul reserves on two engines, which is the big-ticket item. Plan for recurring heater and structural inspections and a fairly involved annual on an older twin, plus insurance that reflects your multi-engine experience. Turbocharged airplanes add exhaust and turbo maintenance. Hangaring is strongly recommended to slow corrosion on airframes this old.
Safety record
NTSB records show 33 PA-23 accidents in the last 10 years, 11 of them fatal and 8 with the aircraft destroyed. Against a registered fleet of 1,302, that is about 25.3 accidents and 8.4 fatal accidents per 1,000 aircraft over the decade. Some of those registered airplanes fly little, and others fly hard in freight or utility work, so the numbers need context. The Aztec itself is known as a stable, forgiving twin. The recurring risk areas are the ones common to all light piston twins: loss of control after an engine failure, especially on takeoff or a go-around, fuel mismanagement across multiple tanks, and gear-related mishaps. On older airframes, maintenance issues such as heater, exhaust or fuel system faults also show up. The best defenses are recurrent multi-engine training with realistic engine-out practice and disciplined fuel management. A careful pre-buy and conservative weather decisions round them out. Most Aztecs are not certified for flight into known icing, so ice is a real limitation.
Alternatives to consider
- Beechcraft Baron 55/58. It is faster and better built, with a more refined feel, but costs more to buy and maintain and carries less in a less forgiving short-field package.
- Cessna 310. It is quicker and sporty to fly, with tip tanks and good speed, but has a tighter cabin and its own corrosion and fuel system quirks.
- Piper PA-34 Seneca. It burns less fuel, has counter-rotating props on later models and is more common for training, but is slower to climb and less capable with heavy loads and on rough strips.
- Piper PA-31 Navajo. It offers a bigger cabin and more payload for charter or freight, with much higher acquisition and operating costs.
- Beechcraft Travel Air / Piper Twin Comanche. These are cheaper and far more fuel-efficient light twins, but have much less cabin, payload and short-field capability.
Frequently asked questions
How much does a Piper Aztec cost?
fyiAero listings currently range from $75,000 to $395,000, with a median asking price of $184,900. Early-1960s airplanes sit at the low end and late-1970s F models at the top. Engine time and avionics heavily influence any individual price.
How much fuel does an Aztec burn?
fyiAero's operating estimate uses about 27.2 gallons per hour at a 178-knot cruise. That works out to roughly $215 per hour in variable costs, or about $1.21 per nautical mile.
Is the Aztec a good first twin?
It is one of the more forgiving light twins, being stable, docile at low speed and roomy. Insurers will still expect formal transition training and may require dual time for low-time multi-engine pilots, so get a quote before you commit.
Should I buy a Turbo Aztec or a normally aspirated one?
Choose the turbo if you regularly use high-elevation airports or want to climb over weather. It adds turbo and exhaust maintenance and usually a higher purchase price. For lower-altitude flying, a normally aspirated Aztec is simpler and cheaper to own.
Does high airframe time hurt an Aztec's value?
Less than you might think. In fyiAero listings, airplanes with 3,000 to 5,000 hours show a $154,000 median versus $162,400 for those over 5,000 hours. Engine condition, avionics and structural history matter more than total time.
How safe is the Piper Aztec?
NTSB records show 33 accidents, 11 of them fatal, over the past 10 years, or about 25.3 accidents per 1,000 registered aircraft. Most twin accidents trace to engine-out handling, fuel management and maintenance rather than airframe design. Recurrent training and a thorough pre-buy are the best protection.
