Cessna 172 Skyhawk


What can be said about the Cessna 172? It's the reason the word "venerable" came into use. First manufactured in 1956, the descendant of the 170 model took the general aviation world by storm with its "Land-O-Matic" tricycle landing gear and made ground control of light aircraft easier and more manageable than ever. One of the world's most popular GA aircraft, it is still in production by Cessna, and trains more pilots than any other aircraft. Despite the fact that it won't win any STOL contests, it possesses all the great flight characteristics of the Cessna 100 series wing, and is easily one of the greatest values on the used market in terms of ownership, utility, and cost of operation. There are 3 main varieties of the 172, distinguished by powerplant:

Years Models Engine
1956-1967 Cessna 172A through 172H Continental O-300 running at 145 HP
1968-1982 Cessna 172I through 172P Lycoming O-320 running at 150-160 HP
1983-present Cessna 172Q through 172S Lycoming O0360 running at 180 HP

Of course the distinctions are many that go beyond just the powerplant, but in terms of utility in the mountains and load hauling, the engine will be a major deciding point.
