1957 saw the birth of Cessna 210. It was a four-seat, single engine with retractable gear general aviation aircraft. It was also powered by Continental IO-470 engine of 250 horsepower (hp). 210 model was the top of Cessna’s single engine model lineup during its production days.

Ever since model 210 entered production, upgrades were constantly made. The early upgrades include the following: wraparound rear windows (which became known in the market as model 210B), the use of a more powerful engine (285hp) and adding 2 child seats (the model became Cessna 210 CENTURION), the wings and fuselage were redesigned; adding a third side window and making the fuselage wider and deeper. A turbocharged 210 model was also introduced in the market and called T210F or Turbo Centurion. A 210G Centurion and Turbo Centurion models went into production in 1967. It replaced the strut-braced wing with cantilever wing and has an increased fuel capacity. The rear window was restyled and the tail surfaces were enlarged.

The 1st six-seat 210 model was introduced in 1970 via 210K Centurion or and Turbo Centurion models. The Cessna 210N Centurion and Turbo Centurion models were introduced in 1979. For this particular model, they removed the folding doors that used to cover the retractable main gears.

One of the greatest developments of the Cessna T210 model is the introduction of a high performance, pressurized P210. It was out in the market in 1978. This aircraft model has a pressurized cabin and four windows in each side. The cabin’s altitude was equivalent to 8000 feet when flying 17,350 feet.

The 210 Centurion and Turbo Centurion models were in production until 1985 when Cessna decided to cease production. Flight training schools; private operators, air taxi and commercial charter and companies popularly used the Cessna 210.

Modifications:

O&N Aircraft offered a turboprop conversion of Pressurized Cessna P210. It was known as the “Silver Eye”. The converted P210 had an airframe overhaul, new avionics, new paint and installation of a Rolls-Royce Model 250 engine. It was also expected that after the conversion P210 would improve in its overall performance as well.

In November 2008, T210 was also remanufactured. It was known as the Crownair “Centurion Edition”. The aircraft featured a glass cockpit and new engine and some other refinements. It also increased in cruise speed, range and payload.
