Cessna 170
Encyclopedia : C : CE : CES : Cessna 170
The Cessna 170 is a general aviation aircraft produced by the Cessna Aircraft Company between 1948 and 1956. Over 5,000 were built, and over 2,000 are still accounted for today. The Cessna 170 landing gear is a taildragger configuration. It was replaced by the Cessna 172 which became the most popular light plane in history.

Variants
The earliest Cessna 170's were essentially four-seat versions of the popular Cessna 140 two-seater, equipped with a more powerful piston engine and additional fuel tanks. Like the 140, they were constructed of metal with fabric-covered wings.
Beginning in late 1948, Cessna began selling the Cessna 170A, an all-metal Cessna 170 with dihedral-less wings. The price was roughly $5,500. This and subsequent versions of the 170 shared the fin/rudder of the larger Cessna 190/195 model.
In 1950, the United States Air Force, Army and Marines began using the military variant of the Cessna 170, the O-1 Bird Dog, as a forward air control and reconnaissance aircraft.
In 1952, the Cessna 170B was released. Sporting a new, dihedral wing essentially unchanged from the military version, the B model now used very effective Semi-Fowler type wing flaps with settings to 40°, and a wing planform that lives on in the Cessna light singles of today. The 170B model also included a new tailplane, a revised tailwheel, larger rear windows and other improvements over the 170 and 170A.
In 1955, the previously elliptical rear side windows were changed to a more squared-off design.
Cessna replaced the 170 with the Cessna 172 in 1956.
