Cessna 210 centurion rolls royce turbo in flight
The Cessna 210 Centurion is a six-seat, high-performance, retractable-gear, single-engine, high-wing general aviation aircraft which was first flown in January 1957 and produced by Cessna until 1985.

Design and development
The early Cessna 210 (210 and 210A) had four seats with a Continental IO-470 engine of 260 hp (190 kW). It was essentially a Cessna 182B to which was added a retractable landing gear, swept tail, and a new wing. In 1961 the fuselage and wing were completely redesigned - the fuselage was made wider and deeper, and a third side window was added. The wing planform remained the same (constant 64" chord from centerline to 100 inches (2,500 mm) out, then straight taper to 44" chord at 208 inches from centerline), but the semi-Fowler flaps (slotted, rear-moving) were extended outboard, from Wing Station 100 to Wing Station 122, which allowed a lower landing speed (FAA certification regulations state that a single-engined aircraft must have a flaps-down, power-off stall speed no greater than 70 miles/hour). To compensate for the reduced aileron span, the aileron profile was changed and its chord enlarged. The 1964 model 210D introduced a 285 hp (213 kW) engine and two small child seats, set into the cavity which contained the mainwheels aft of the passengers.
In 1967 the model 210G introduced a cantilever wing replacing the strut-braced wing. Its planform changed to a constant taper from root chord to tip chord. In 1970 the 210K became the first full six-seat model. This was achieved by replacing the flat leaf-springs used for the retractable main landing gear struts (undercarriage) with tapered tubular steel struts of greater length. This allowed the tires to be nested farther to the rear of the fuselage, making room for the full-size rear seats. In 1979 the 210N model eliminated the folding doors which previously covered the two retracted main wheels. The tubular spring struts retract into shallow channels along the bottom of the fuselage and the wheels fit snugly in closed depressions on the underside of the fuselage. Some models featured de-icing boots as an option.
The aircraft was offered in a normally aspirated version, designated the model 210, as well as the turbocharged T210 and the pressurized P210 versions. The Centurion II was an option introduced in 1970 with improved avionics, and was available in both normally aspirated and turbocharged versions (Turbo Centurion II)
On 21 May 2012 the airworthiness authority responsible for the design, the US Federal Aviation Administration, issued an emergency Airworthiness Directive requiring 3,665 of the cantilever wing Cessna 210s to be inspected for cracks in the spar cap, wing spar and wing. Aircraft with more than 10,000 hours of airframe time were grounded immediately pending a visual inspection.
Succession
In November 2007, Cessna acquired the assets of Columbia Aircraft Company. The Columbia 350 and 400 models were integrated into the Cessna single-engined range and redesignated as the Cessna 350 and Cessna 400. These aircraft replaced the Cessna 210 at the top end of the Cessna single-engined model line.
Modifications
There are a wide range of modifications available for the Cessna 210, including:
Aeronautical Engineers Australia has developed a life extension package for 210s suffering from wing spar carry-through beam corrosion.
Crownair Aviation developed a “Centurion Edition” T210, which is a remanufactured aircraft introduced in November 2008 that features a glass cockpit and new engine along with other minor refinements.
O&N Aircraft offers a Rolls-Royce Model 250 turboprop conversion of the T210 and Pressurized Cessna P210N known as the "Silver Eagle".
Riley Rocket - Restoration and addition of intercooler to Continental TSIO-520 models to boost from 310 to 340 hp (231 to 254 kW).
Vitatoe Aviation offers the TN550 conversion which uses a Continental IO-550P engine with an IO-520 turbocharger with dual intercoolers and a larger alternator.
Variants
The Cessna 210 was manufactured in 26 model variants. The C210, C210A-D, the Centurion C210E-H&J, Turbo Centurion T210F-H&J, the Centurion II C210K-N&R, the Turbo Centurion II T210K-N&R and the P210N&R. The 210N, T210N (turbocharged), and P210N (pressurized) versions were produced in the greatest quantity. The rarest and most expensive models were the T210R and P210R, which were produced only in small quantities in 1985-86.
Several modifications and optional fittings are also available including different engine installations, wingtip tanks, speed brakes, STOL kits and gear door modifications.
The early strut-winged Cessna 210B was developed into a fixed-gear aircraft known as the Cessna 205. This spawned an entirely new family of Cessna aircraft including the 206 and the eight-seat 207.

Accidents and incidents
On 12 July 1968, Leonard Bendicks hijacked a Cessna 210 from Key West, Florida, to Cuba. He was deported to the US in September 1968. On 4 March 1971, he was sentenced to 10 years for kidnapping.
While flying N6579X, an early model 210A, famed test pilot Scott Crossfield crashed and died in the woods of Ludville, Georgia on April 19, 2006. The National Transportation Safety Board established the probable cause as "The pilot's failure to obtain updated en route weather information, which resulted in his continued instrument flight into a widespread area of severe convective activity, and the air traffic controller's failure to provide adverse weather avoidance assistance, as required by Federal Aviation Administration directives, both of which led to the airplane's encounter with a severe thunderstorm and subsequent loss of control."
On 9 August 1981, a Cessna 210M, VH-MDX crashed in or near Barrington Tops in NSW, killing all 5 on board. It is the only post WWII incident in Australia in which the aircraft remains missing. The ATSB reports mentions icing, violent weather, and instrument failure.
