The Cessna Model 170 aircraft is a development of the Model 140, featuring a new engine and an enlarged cabin capable of accommodating four people. The machine proved to be successful, resulting in the Model 170 and Model 172 becoming the most mass-produced aircraft by “Cessna”.

First Flight and Initial Design

The prototype of the Model 170 made its first flight in November 1947. Its fuselage was all-metal, the wing’s structural frame was made of aluminum, and the covering was fabric. The prototype was equipped with a 6-cylinder Continental C-145 piston engine, delivering 145 hp.

Evolution and Series Production

A large family of modifications was created based on the Cessna Model 170. In 1948, 729 Model 170 aircraft were assembled, after which production shifted to the Model 170A, featuring an all-metal wing of modified shape, single wing struts, and a large area dorsal fin. Wheel fairings for the main landing gear first appeared on the newly built Model 170A, but were subsequently installed on all aircraft of the Model 170 family.

A total of 1536 Model 170A aircraft were built, and between 1952 and 1956, 2907 Model 170B aircraft were assembled. The 170B was equipped with the C-145-2 engine (later O-300), characterized by slotted air intakes to the right and left of the propeller. The wing of the 170B was also fitted with Fowler flaps. Over nine years of series production, 5172 aircraft of all variants of the Model 170 were produced.
