The Cessna 205, 206, and 207, known variously as the Super Skywagon, Stationair, and Super Skylane are a family of single engine, general aviation aircraft with fixed landing gear used in commercial air service and also for personal use. The family was originally developed from the popular retractable-gear Cessna 210.
The line's combination of a powerful engine, rugged construction and a large cabin has made these aircraft popular bush planes. Cessna describes the 206 as "the sport-utility vehicle of the air." These airplanes are also used for aerial photography, skydiving and other utility purposes. They can also be equipped with floats, amphibious floats and skis. Alternatively, they can be fitted with luxury appointments for use as a personal air transport.
Between the start of production in 1962 and 2006 the total Cessna 205, 206 and 207 production has been 8509 aircraft so far.
The 205 is powered by a Continental IO-470-S engine producing 260 hp.
The 205 was officially designated by Cessna as a "Model 210-5"
The 205 was only produced in two model years - 1963 and 1964 before being replaced in production by the Cessna 206. A total of 576 Cessna 205s were produced.
There were many sub-variants, including the U206, P206 all certified to CAR3 standards and later 206H certified to FAR Part 23.
The total Model 206 production between 1964 and 2004 was 6581 aircraft.
There was a TU206 turbocharged version powered by the Continental TSIO-520-C engine producing 285 hp. After 1967 the turbo TU206 was powered by a TSIO-520-F of 300 hp (the extra 15 hp were obtained by turning the engine at a higher rpm, and was only allowed for five minutes. Due to the large propeller diameter, the additional engine speed meant that the propeller tips were pushed to transonic speeds, which required much more power. Thus the extra 15 hp did not produce much performance improvement but did produce an unpleasant noise).
From 1964 to 1969 the U206 was known as the “Super Skywagon”. From 1970 it was named the “Stationair”, a contraction of “Station Wagon of the Air”, which is a good description of the aircraft's intended role. Sub-variants were designated U206 to U206G.
In 1977 the U206 had its engine upgraded to a Continental IO-520-F of 300 hp (continuous rating, obtained at a more reasonable speed than the previous IO-520-F) and the TU206 powerplant was changed to the TSIO-520-M producing 310 hp.
Production of all versions of the U206 was halted in 1986 when Cessna stopped manufacturing all piston engine aircraft. A total of 5208 U206s had been produced.
The P206 was produced from 1965 to 1970 and was powered by a Continental IO-520-A of 285 hp. There was a turbocharged model designated TP206 which was powered by a Continental TSIO-520-A also of 285 hp.
647 P206s were produced under the name “Super Skylane” which made it sound like a version of the Cessna 182, which it was not. Sub-variants were designated P206 to P206E.
The 206H is powered by a Lycoming IO-540-AC1A powerplant producing 300 hp. The turbocharged T206H is powered by a Lycoming TSIO-540-AJ1A engine of 310 hp.
Even though the Cessna 206H is certified as a six seat aircraft in its country of origin, the Canadian aviation regulator, Transport Canada has only certified it to carry five people in Canada. This is due to concerns about passenger egress through the rear clamshell door with the flaps extended. Cessna addressed one part of this problem early on, after a flight-test aircraft was damaged when the pilot extended the flaps while taxiing, and his passenger had the clamshell door open (for ventilation; it was a hot summer day). A switch was added to the flap actuation circuit which disabled the flaps when the doors were open. The other part of the problem is that if the flaps are already down, the passenger must perform the complicated procedure of opening the front part as far as possible (about 2 inches) then open the rear door and restow the rear door handle. This then gives enough clearance to open the rear part of the door.
Both the 206H and the T206H remain in production in 2008. By the end of 2004 Cessna had produced 221 206Hs and 505 T206Hs, for a total production of 726 "H" models.
Cessna has indicated that they do not intend to produce a P206-configuration aircraft in the future, due to lack of market demand.
The 207 was introduced as a 1969 model featuring a Continental IO-520-F engine of 300 hp. A turbocharged version was equipped with a TSIO-520-G of the same output.
At the beginning of production the model was called a Cessna 207 “Skywagon”, but in 1977 the name was changed to “Stationair 7”. 1977 also saw a change in engine on the turbocharged version to a Continental TSIO-520-M producing 310 hp – the same engine used in the TU206 of the same vintage.
The 207 added a seat in 1980 and was then known as the “Stationair 8”. Production of the 207 was completed in 1984, just two years before U206 production halted. A total of 626 Cessna 207s were manufactured.
The Cessna Model 207 has been popular with air taxi companies, particularly on short runs where its full seating capacity could be used. Very few of these aircraft have seen private use.
In April 2007 Thielert announced that the European Aviation Safety Agency had granted a Supplemental Type Certificate (STC) for conversion of Cessna 206s to the Thielert V-8 diesel powerplant. The STC allows conversion of the following models: U206F and TU206F with the 300hp powerplant, and the U206G, TU206G, 206H and T206H with the 310hp version. This modification does not require any changes to the engine cowling. In May 2008, Thielert entered insolvency proceedings, so the future availability of this diesel conversion is uncertain.
Soloy Aviation Solutions offers a turboprop conversion for all 205/206/207 models based on the 418 SHP Allison C20S engine. However, extensive engine cowl modifications are required.
Both Kenmore Air (Edo floats) and Wipair (Wipline floats) offer seaplane conversions.
