Originally a public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

The Cessna 170 is a light, single-engined, general aviation aircraft produced by the Cessna Aircraft Company between 1948 and 1956.

It is the predecessor of the Cessna 172, which is the most produced aircraft in history...

Development

170

In late 1948, Cessna began sales of the 170, with a metal fuselage and tail and fabric-covered constant-chord wings. These earliest 170s were four-seat versions of the popular 140 with a more powerful 145 hp (108 kW) Continental C145-2 and larger fuel tanks. Like the 140, they were constructed of metal with fabric-covered wings supported by a "V" strut.

170A

In 1949 Cessna began marketing the 170A, an all-metal 170 with zero-dihedral wing tapered outboard of the slightly-enlarged plain flaps, and a single strut replacing the "V" strut of the 170. This and subsequent versions of the 170 shared the fin/rudder shape of the larger Cessna 190 and 195 models.

305

In 1950, the United States Air Force, Army and Marines began using the military variant of the 170, the Model 305, designated the L-19 and later O-1 Bird Dog by the military. It was used as a forward air control and reconnaissance aircraft. The Bird Dog was extensively redesigned from the basic 170 and included a revised tandem-seat fuselage and a wing with large modified Fowler flaps that deployed up to 60°.

170B

In 1952, the Cessna 170B was introduced, featuring a new wing tapered outboard of the flaps, incorporating dihedral similar to the military version. The B model was equipped with very effective modified Fowler (slotted, rearward-traveling) wing flaps which deflect up to 40°, adapted from the C-305/Bird Dog, a wing design that lives on in the Cessna light singles of today (constant NACA 2412 section with a chord of 64 inches (1,600 mm) from centerline to 100 inches (2,500 mm) (the outboard end of the flaps), then tapering to 44-inch (1,100 mm) NACA 2412 section chord at 208 inches from centerline, with three-degree washout across the tapered section). The 170B model also included a new tailplane, a revised tailwheel bracket, and other refinements over the 170 and 170A. It was marketed in 1952 for $7245.

In 1955, the previously elliptical rear side windows were changed to a squarer design.

Experimental

In 1958 Cessna experimented with a belt driven 145 hp Continental engine. The company completed 1000 hours of test flying. The belt drive reduced vibration, engine noise and propeller noise. A 92 inch propeller with 70 degrees of pitch improved the rate of climb 12 percent. The belts used were developed by Goodyear Tire and Rubber Company and were 3/8-inch wide, 7/16-inch deep, and 41 inches long.

Successor

The 170 is equipped with conventional landing gear, which is more challenging to land than tricycle landing gear. In 1956, Cessna introduced a replacement for the 170 that was essentially a nosewheel-equipped 170B with a square tailfin, designated the 172. 170 production was halted soon after the 172 became available...
