Cessna 210


In 2000, Cessna’s first retractable single turned 40. No doubt, the engineers employed by the Wichita manufacturer would be amazed to learn that their handiwork is prized as the model enters its fifth decade. So much so that pilots with large families and a penchant for speed may want to take this opportunity to face the general direction of Kansas and salute. Although it wasn’t so in the beginning, the Cessna 210, eventually called Centurion, would become an alluring high-performance load-hauler. Its ability to tote a serious load at speeds fully reasonable for the installed power has made the 210 a top seller when new and quite desirable as a used aircraft.

Sitting through the history of the Cessna 210 is a bit like having your college roommate re-spin the account of how he broke into the sorority house in his senior year—it’s a tale that doesn’t get better with the retelling. (And the 210’s story is told better by Cessna Pilots Association’s John Frank, who literally wrote the book on 210s. Call 805/922-2580 or visit to order.) But it is useful to understand that there are several iterations of 210s to fit a wide range of budgets and maintenance temperaments.

Earliest of all 210s are the 1960 models, actually introduced in the twilight of the 1950s; they are basically 182 airframes fitted with retractable landing gear and a fuel-injected version of the Skylane’s 470-cubic-inch Continental, rated at 260 horsepower. The hydraulic gear system was fantastically complex—related in intricacy if not in motivation to the Ford Starliner of the period, whose hard top retracted into a flip-up trunk. (You get the idea that in the late 1950s we thought we could accomplish any engineering task by throwing more stuff at it?)

Cessna got cracking on improving the 210, first by adding more windows and then, in 1962, widening the cabin by four inches. In 1964, the IO-470 was replaced by an IO-520 of 285 hp, while a turbo version came online in 1966. For 1967 the dowdy struts gave way to a new cantilever wing with 3 degrees of dihedral. Many pilots thought that these first strutless 210s looked funny, so Cessna reduced the dihedral angle by half for the 1969 model, necessitating a rudder-aileron interconnect to maintain suitable directional stability at low speeds. The next year, Cessna revamped the cabin again, making the 210 a six-placer and switching from four side windows to two large ones.

Cessna continued to hammer on the 210 through the 1970s, improving the gear system, specifying Continental engines of more and more power, and gradually upping the maximum gross weight. In 1979, the 210 reached its height of popularity and, coincidentally, shed its clamshell main gear doors for open slots in the aft fuselage. Ironically, Cessna finished in 1985 and 1986 with the 210R models, a substantially modified airplane that would have suited the company well into the 1990s, had it elected to keep the 210 line open.

Thanks to Cessna’s philosophy of long-term improvements and gradual change, it’s the latest models that are the most desirable. The 210R—available in 310-hp nonturbo, 325-hp turbocharged, and 325-hp pressurized iterations—is high on the desirability scale, although also depressingly rare. Fewer than 175 R models were built.

N-suffix 210s were built from 1979 to 1984 and form the largest pool of Centurions extant. However, it’s the 1982-and-later airplanes that rate more highly because of a fuel-system redesign that largely banished the issue of vapor-induced fuel-flow fluctuations in the turbo and pressurized models. For the first time, there was a Both position on the fuel selector.

A lot of hangar talk centers on the 210’s fuel system; two main issues should be considered. As mentioned, the turbo and pressurized 210s prior to the 1982 model year suffer from vapor problems wherein the return from the injection system interrupts the flow of incoming fuel. Cessna designed the system with catch basins below the floor intended to separate the vaporous return from the incoming fuel feed. This system meant that there could be just two fuel lines (one front, one rear) from the tank to the reservoir tanks with no need for a separate vapor-return conduit. It’s a nice, elegant engineering idea that didn’t work very well. Flow interruptions are most commonly found on hot days but can be easily cured with judicious use of the boost pump and by switching tanks; experienced 210 pilots consider this slightly annoying but otherwise a non-issue. Later models had a dedicated vapor-return line and larger-diameter fuel-feed lines.

A fair number of 210s have experienced fuel exhaustion, often attributed to improper filling of the integral wing tanks. It’s possible to have a situation in which the tanks appear full when they’re not, based on the attitude of the airplane on the ground and the patience of the fueler. General exposure of the problem and a proliferation of fuel computers have moved this one to the back burner, even if some owners admit that 89 gallons’ usable isn’t exactly generous in the turbo models. (Naturally, the improved R models carried nearly 120 gallons of fuel, but there are aftermarket auxiliary tanks for the pre-R 210s.)

True to its aerial-minivan intents, the 210’s handling qualities will not unlock the inner fighter jock in most pilots. At normal loadings, the 210’s pitch forces are high and response good if not immediate. Roll forces are light, with yaw response in between. With an aft loading, you might be convinced that you’ve boarded a different airplane, but the 210 nonetheless maintains its trademark Cessna safety-over-sexy handling qualities. As is true with many designs, the early airplanes are more pleasing in handling than the later, heavier models, with the exception of the last-of-line Rs. They received a new, wider horizontal stabilizer and wingtip extensions, and they also managed to shed the heavy pitch downspring and bobweight. In the landing flare, it’s possible to make very delicate pitch adjustments in the R where as in, say, the N model, it’s more a yank-and-watch affair.

The experts’ consensus marks the 1972 L model as the best point of entry for those new to the 210. By then, the 210 had the large cabin, cantilever wing, and a revised landing-gear hydraulic system that relied on an electric power pack; this replaced the old engine-driven pump.

Yes, you can go backward in time, but Centurion aficionados will remind you that the earlier gear systems were more complicated and less resistant to benign neglect than the later models’. That’s not to say the 210 gear system is dangerously fussy or frustratingly unreliable. It is, however, much less tolerant of neglect than other systems. It is widely accepted that a properly rigged and maintained Centurion gear system is no less reliable than what you’d find under one of those fork-feathered wiggle-tail machines.

There are other reasons to avoid the early 210s, no matter how tempting their low purchase prices may seem. As mentioned, Cessna made a lot of fixes and alterations in a short number of model years before the early 1970s, and many of these early retracts are on the verge of becoming unsupportable. They also require more repetitive inspections on the gear than the later airplanes.

What, then, is the future of the Centurion? Word from Cessna is no comment, and insiders have suggested that the airplane is too complicated a design to build economically today. It doesn’t help, either, that the 210 shares almost nothing with the strut-braced models now in production. Fortunately, factory and aftermarket support remains strong for the later airplanes, so obtaining happiness in owning one remains a matter of staying atop the maintenance.

Performance Summary

The 210 is an all metal, six place, high wing, single engine airplane equipped with retractable tricycle landing gear and is designed for general utility purposes.
This airplane is certificated in the normal category. Spins and aerobatic maneuvers are not permitted in normal category airplanes. The airplane is approved for day and night VFR/IFR operations when equipped in accordance with F.A.R. 91 or F.A.R 135.

The airplane is powered by a horizontally opposed, six cylinder, direct drive, normally aspirated, air cooled, fuel injected engine. The engine is a Continental Model IO-520-L and is rated at 285/300 horsepower.

The airplane fuel system consists of two 45 gallon vented integral fuel bays. Fuel flows from these bays through a reservoir tank to the fuel selector valve, through a bypass in the electric auxiliary fuel pump and the furl strainer to the engine-driven fuel pump. From here fuel is distributed to the engine cylinders via a control unit and manifold. Vapor and excess fuel from the engine-driven fuel pump and fuel control unit are returned by way of the selector valve to the reservoir tank of the wing fuel bay system being used.

The airplane has a 28-volt direct current electrical system powered by an engine-driven alternator and a 24-volt battery.
