Cessna 210 vs A36 Bonanza: Which to Buy

The Cessna 210 Centurion and Beechcraft A36 Bonanza are two of the most capable six-seat retractable singles in the used-aircraft market. Both offer roughly 300 horsepower, useful cross-country speed and enough payload for serious family or business travel, but they approach the mission differently. The 210 emphasizes useful load, fuel capacity and cabin utility, while the A36 focuses more on passenger access, handling and long-term support.

The honest answer to Cessna 210 Centurion vs Beechcraft A36 Bonanza is not "one is better." It is that these two airplanes solve the six-seat problem in opposite ways. The Cessna trades a little polish for payload and fuel. The Beech trades a little payload for build quality, cabin access and the best factory support network in piston aviation. Think of it as a three-quarter-ton pickup versus a well-sorted German wagon. Both get the family there. They do not feel the same doing it, and they do not cost the same to keep.

This article is about the decision a buyer actually faces: what you get for your money, what each airframe will ask back from you in maintenance, and which one fits the mission you fly most weekends. We are going to spend real time on the things that move money, including the Cessna 210 carry-thru spar airworthiness directive, the 210's hydraulic gear system, Bonanza parts pricing, and how the useful-load math changes when you actually fill all six seats.

Key Takeaways

The Cessna 210 is the load hauler: higher gross weight, more usable fuel, more cabin volume behind the front seats, and a purchase price that usually runs well below a comparable-year A36. The A36 Bonanza is the better-built, better-supported, nicer-flying airplane, with double aft cabin doors that make loading passengers and cargo genuinely easy, and it holds value stubbornly well. Speed is close enough to call a tie in normally aspirated form, with both cruising in the neighborhood of 165 to 175 knots true on 15 to 17 gallons an hour. On earlier 210G through 210M models, a major consideration is FAA AD 2020-03-16 covering the wing carry-thru spar; later 210N and 210R models are not included in that AD but are covered by Cessna inspection guidance. The Bonanza's major ownership consideration is generally higher parts pricing.

Where Each Airplane Came From

What is the Cessna 210 Centurion?

Cessna built the 210 from 1960 to 1986, and it changed a lot along the way. The earliest airplanes were strut-braced and smaller; from the 1967 model year the wing went cantilever, which is the shape most buyers picture. Power grew from 260 to 285 and finally to 300 horsepower with the Continental IO-520-L in the 210L and later. Turbocharged T210 models arrived early and stayed, and from 1978 Cessna also offered the pressurized P210 with a cabin you could fly in the flight levels without a mask.

The airplane is certificated under FAA type certificate data sheet 3A21, and later models carry a detail every buyer should know: starting with the 1979 model year, Cessna deleted the main landing gear doors on the 210. That single change removed a notorious maintenance headache. The doors were driven by the same hydraulic system that retracts the gear, and when the sequencing valves and seals aged, owners paid for it.

Good to Know: If a broker tells you a 210 is "gear-door free," they are describing 1979 and later airframes. Everything earlier still has main gear doors, and on a pre-buy that system deserves its own hour of attention.

What is the A36 Bonanza?

Beechcraft stretched the straight-tail Debonair/Model 33 fuselage, moved the rear bulkhead back, cut in double cargo doors on the right side, and called it the Model 36 in 1968. The A36 followed in 1970 and stayed in production, in various forms, into the modern G36 with glass panels. Early A36s use the 285-horsepower Continental IO-520-BB; from the 1984 model year Beech switched to the 300-horsepower IO-550-B, which is the version most buyers chase. Turbocharged A36TC and B36TC models exist with the TSIO-520-UB and a different, longer wing on the B36TC.

If you want the family tree, we have already covered how the straight-tail airplanes differ in Beechcraft Debonair vs Bonanza, and how the 36 stacks up against Piper's six-seater in Bonanza vs Saratoga.

Performance: Closer Than the Rivalry Suggests

Which one is actually faster?

At the same horsepower, the two airplanes are within a few knots of each other. A clean, normally aspirated A36 with the IO-550-B will show about 172 to 176 knots true at 75 percent power in the mid altitudes. A well-rigged 210N with the IO-520-L does 165 to 172 knots. Most owners report the Bonanza is a couple of knots quicker on the same fuel, and that the gap widens or closes depending on antennas, paint, wheel fairings and how honest the airspeed indicator is.

Where the 210 pulls ahead is endurance. With 89 usable gallons against the Bonanza's 74, the Centurion simply flies longer. At about 15 gallons per hour, that is roughly five and a half hours of fuel versus four and a half, before reserves. On a 700-nautical-mile leg into a headwind, that difference is the whole ballgame.

Why It Matters: Cruise speed sells airplanes; fuel capacity finishes trips. A 5-knot speed advantage saves you about ten minutes on a 600-mile leg. Fifteen extra gallons can save you an entire fuel stop, which is closer to forty-five minutes plus a landing fee.

What about the turbocharged versions?

The T210 climbs into the mid-20s and holds book speed up high, which makes it a legitimate weather and terrain airplane for the western states. The A36TC and B36TC do the same job with a bit less cabin. Both come with the same warning: turbocharged Continental 520-series engines have shorter published time between overhauls, generally in the 1,400 to 1,600 hour range, and they punish careless temperature management. If you are not going to fly above 12,000 feet regularly, the normally aspirated versions are cheaper to own by a wide margin.

The Six-Seat Question: Payload, Cabin and Doors

Can either airplane really carry six people?

With full fuel, neither one can. That is not a knock on these airplanes; it is true of nearly every piston six-seater. Do the arithmetic honestly. A 210N with a 1,500-pound useful load and 89 gallons aboard has burned 534 pounds on fuel, leaving roughly 966 pounds for people and bags. That is four adults and luggage, or five adults and a light load if you run partial fuel. An A36 with a 1,250-pound useful load and 74 gallons has about 806 pounds left, which is four adults and a couple of bags.

Run either one at partial fuel and the picture improves fast. Fill the 210 to 60 gallons and you are carrying over 1,100 pounds of people, which really is six adults for a two-and-a-half-hour leg. The Cessna's higher gross weight and bigger fuel tanks give it more room to trade, and that flexibility is the single strongest argument in its favor.

Keep in Mind: Useful load on a 40-year-old airframe is whatever the current weight and balance says, not what the brochure said in 1979. Air conditioning, a heavy old autopilot, speed mods, extra avionics and thick paint can eat 100 pounds or more. Always ask for the current weighing data before you get excited about a number.

Which cabin is nicer to live with?

The A36 wins on access and loses on volume behind the third row. Those double aft doors are a genuinely great piece of design. Grandparents get in without climbing over a wing or a front seat. Club seating puts the middle and rear passengers facing each other with legroom. Load a bicycle, a dog crate or a folded wheelchair and you will appreciate the opening.

The 210 answers with a taller, boxier cabin and a large baggage area behind the rear seats, plus the high wing's practical advantages: shade on a hot ramp, a dry entry in rain, and a view straight down that sightseeing passengers love. What it does not have is an aft door. Rear-seat passengers come in through the front, which gets old if you carry non-pilots often.

Pro Tip: Bring the people you actually fly with to the showing and have them board the airplane. Twice. A cabin that is awkward on a sunny afternoon at your home field is worse in the rain at a strange FBO with a ramp full of onlookers.

Maintenance Reality: The Two Items That Move Money

What is the Cessna 210 spar AD, and should it scare you?

In 2019 a T210M suffered an in-flight wing separation in Australia after fatigue cracking developed from corrosion in the wing carry-thru spar lower cap. The FAA responded with AD 2020-03-16, requiring visual and eddy-current inspections on Models 210G through 210M and the corresponding T210 variants. The AD does not apply to the later 210N, T210N, P210N or 210R-series airplanes, although Cessna's service guidance calls for carry-thru spar inspections on those models as well.

Should it scare you off? No, but it should structure your search. Ask for documented compliance with the AD, the inspection method used, the findings, and the next due point. An airplane with a clean, recent inspection and clear paperwork is worth real money over one with a vague logbook entry. Cessna also publishes Supplemental Inspection Documents for the 210. They are not mandatory for Part 91 operators in the United States, but a shop that has worked through them has told you a great deal about the airframe's condition.

Heads Up: Budget separately for the 210's hydraulic landing gear system. The power pack, actuators, hoses and saddle assemblies all age, and on pre-1979 airplanes the gear doors add complexity. A gear system that has been recently overhauled by a shop that knows 210s is a meaningful part of the asking price.

What does the Bonanza cost that the Cessna does not?

Parts. Beech parts have always carried a premium, and on a 1970s A36 some items are single-source. Fuel bladders deteriorate with age and are a known recurring expense on Beech singles; a full set with labor is not a small invoice. Landing gear rigging is a specialist job, and the retract system's actuator and rod-end wear is exactly what type-club service clinics look for. Magnesium control surfaces on older airframes need corrosion attention.

The offsetting good news is support. The American Bonanza Society runs service clinics, publishes detailed technical guidance and maintains a network of shops that have seen every failure a Model 36 can produce. There is nothing else quite like it in piston aviation, and it genuinely lowers the risk of buying an unfamiliar airframe.

What about the engines?

Both airplanes run Continental big-bore six-cylinder engines, so the ownership experience rhymes. Continental publishes recommended TBO in its Service Information Letter SIL98-9 series; the IO-520 is generally listed at 1,700 hours and the IO-550 higher, with turbocharged variants lower. Overhaul quotes for these engines have climbed steadily, and a factory rebuilt or quality field overhaul plus accessories is a five-figure event that you should be reserving for every hour you fly, not discovering at year eight.

The IO-550-B in the 1984-and-later A36 is generally considered the sweeter installation of the two, partly because of the engine and partly because Beech refined the baffling and cooling around it. Many older 285-horsepower A36s have been converted to IO-550 power by supplemental type certificate, which is worth confirming in the records rather than trusting the ramp talk.

Those are planning ranges, not quotes. Fuel price, hangar rent, avionics age and your region all swing them. If you want a structured way to build your own number, our operating cost worksheet walks through the fixed and variable split.

Buying: Price, Paperwork and Pre-Purchase

Which one costs less to buy?

The 210, almost always. Compare a mid-1970s 210L against a mid-1970s A36 with similar avionics and engine time and the Beech typically commands a noticeable premium, often on the order of 20 to 40 percent. Late 210Ns and 210Rs narrow the gap, and clean P210s occupy their own market. On the Bonanza side, the 1984-and-later IO-550 airplanes sit clearly above the earlier 285-horsepower ones, and the later the airframe, the steeper the curve.

Prices in this segment move with fuel, interest rates and the supply of good airframes, so treat any published figure as a snapshot. What does not change is the shape of the market: Bonanzas depreciate slowly and resell quickly; 210s cost less to get into and are more sensitive to condition, especially spar AD status and corrosion history. If you are weighing new versus used generally, our piece on the benefits of buying a used plane covers the broader trade.

Flying411 keeps asking prices, specs and photos for six-seat retractable singles in one place, so you can see how a 210N and an A36 of the same vintage are actually priced against each other.

What should a pre-purchase inspection cover on each?

Use a shop that specializes in the type. That advice gets repeated because it keeps being true. For an affected 210G through 210M, you want documented AD 2020-03-16 compliance; on later 210s, verify compliance with the applicable Cessna carry-thru spar inspection guidance. In either case, give the carry-thru spar area a hard look. For the A36, you want gear rigging and retraction timing verified, fuel bladders assessed for age and condition, wing bolt and spar carry-through area inspected, and the aft fuselage and control surfaces checked for corrosion.

On both airplanes, pull a full AD search and a complete damage history. And read the logbooks yourself. A 45-year-old airframe with a thin book is not a bargain; it is a mystery. Our guide to reviewing aircraft logbooks before you buy lays out what to flag.

Quick Tip: Ask the seller who has been maintaining the airplane and call that shop. Five minutes on the phone with the mechanic who has signed the last six annuals tells you more than any listing description.

Insurance, Training and Getting Signed Off

Will an insurer cover a low-time buyer in either one?

Both are high-performance, complex singles, so you need the endorsements required under 14 CFR 61.31 for complex and high-performance airplanes, and in practice underwriters want more than the regulation does. Expect requests for a few hundred hours total time, an instrument rating, and 10 to 25 hours of dual in type with a named instructor before solo. Retractable-gear six-seaters sit in a claims category insurers watch closely, and gear-up landings are the reason.

Bonanza buyers have a strong card to play here: completing the American Bonanza Society's pilot proficiency program frequently earns a premium credit and, just as importantly, teaches you the airplane's systems from people who fly them daily. Cessna 210 owners should seek out a 210-experienced instructor and a type-focused owner group; the gear system in particular rewards a pilot who understands what the hydraulic pack is doing on each cycle.

Fun Fact: The 210 has done jobs most light singles never see. Survey operators, freight haulers and skydiving clubs have used Centurions for decades precisely because the cabin swallows load and the gross weight allows it. If you see a 210 with 10,000 hours on the airframe, that is why.

So Which One Should You Buy?

Buy the Cessna 210 if...

You haul weight and bulk more than you haul dignitaries. You fly long legs and want the fuel to do them nonstop. You like the high-wing view, the shade and the easier loading of awkward cargo. You want the lower entry price and you are disciplined enough to reserve for the gear system and the spar inspections. And you are comfortable being your own advocate on parts sourcing, because Textron's support for a 1970s 210 is not the same as a type club that specializes in one family of airplanes.

Buy the A36 Bonanza if...

You want the nicer airplane and you are willing to pay for it twice, once at purchase and again at every annual. You carry passengers who will appreciate those aft doors and club seats. You value the handling, which most pilots who have flown both describe as noticeably more harmonized in the Beech. You want a strong resale market and an owner community that has already solved whatever problem you are about to have. If you are weighing the Bonanza against other four- and six-seat options, our comparisons of the Bonanza and the Piper Cherokee and the Cessna 210 and the 172 help frame how much airplane you actually need.

Flying411 keeps specifications, photos and current listings for both types in one place, so you can compare engine time, avionics and asking price before you spend a dime on a pre-buy.

Conclusion

The Cessna 210 Centurion vs Beechcraft A36 Bonanza decision comes down to two honest questions. First, is your mission about weight and range, or about comfort and refinement? Second, how much annual maintenance variability can your budget absorb without turning flying into a chore? The 210 gives you more airplane for less money up front and asks you to stay on top of a well-documented spar inspection and a busy gear system. The A36 costs more going in and going through, and gives back build quality, cabin access, unmatched type support and a resale value that barely blinks.

There is no wrong answer here, only a wrong match. Pick the airplane whose weak points you can live with, hire a type-specialist shop for the pre-buy, and buy the best-documented example you can find rather than the cheapest one on the ramp. In this market, paperwork is worth more than paint.

Frequently Asked Questions

Is the Cessna 210 safe to buy after the spar airworthiness directive?

Yes, but first determine whether the specific model is subject to AD 2020-03-16. The AD applies to Models 210G through 210M and corresponding T210 variants, but not the later 210N, T210N, P210N or 210R-series airplanes. Regardless of AD applicability, review the airplane's carry-thru spar inspection history and have a 210-experienced shop examine the area during the pre-purchase inspection.

Which airplane has the better useful load?

The Cessna 210. A 210N is certificated to 3,800 pounds gross weight against roughly 3,600 to 3,650 pounds for the A36, and it carries 89 usable gallons versus 74. Typical 210 useful loads run around 1,400 to 1,600 pounds; typical A36 figures are closer to 1,100 to 1,350. Always confirm against the specific airplane's current weight and balance.

Is the A36 Bonanza really faster than a 210?

Marginally. A 1984-or-later A36 with the 300-horsepower Continental IO-550-B typically cruises around 172 to 176 knots true, while a 300-horsepower 210 runs about 165 to 172. Rigging, speed mods and airframe condition can erase or widen that gap on any individual airplane.

Which is cheaper to own over five years?

For most owners, the 210, mainly because of the lower acquisition cost and lower parts pricing. The gap narrows if the 210 needs gear system work or if spar inspections turn up findings. Both burn similar fuel and both run Continental big-bore engines with similar overhaul costs, so the differences show up in purchase price, parts and resale.

Should I consider the turbocharged or pressurized versions?

Only if you will regularly fly above 12,000 feet. Turbocharged Continental 520-series engines carry shorter published overhaul intervals and demand careful temperature management, and the pressurized P210 adds a whole system to maintain. If your typical trip is three hours at 8,000 feet, a normally aspirated airplane will cost you far less.

What training will my insurance company require?

Expect complex and high-performance endorsements under 14 CFR 61.31 plus 10 to 25 hours of dual in type, and often an instrument rating, before you are covered solo. Bonanza buyers who complete the American Bonanza Society's proficiency program frequently see a premium credit. Cessna 210 buyers should seek out an instructor with real 210 time, especially for gear system knowledge.
