Buying a Cessna 172 (part 2 of 5)

by Jason Schappert

Which Model is Right for You?

Since 1956 a lot has been done to our beloved Cessna 172. With so many models and possible upgrades it’s hard to choose the 172 that’s for you.

Below we’ve listed a few of the more popular models, where Cessna made significant changes to the 172.

172 – As previously stated in the first post, Cessna equipped the 172 with a 145 horsepower Continental 0-300. Over a span of 5 years they manufactured 4195.

172B – In 1961 Cessna redesigned the cowling, spinner, and lengthened the engine mounts. After these minor upgrades they first deemed their airplane the “Skyhawk.”

172D – Up until 1963 the 172 featured what’s know as a “straight tail” with no rear window. The 172D was the first model to equip the fuselage with a rear window, known in 1963 as “Omni-Vision.” The 172D also saw the upgrade to a Continental GO-300E featuring 175 horsepower.

172F – In 1965 Cessna introduced electric flaps to replace it’s lever system.

172H – Cessna discontinued the Continental 0-300 in 1967 and the 172H was the last model to feature this engine.

172I – 1968 started Cessna’s well know Lycoming powered 172. The Lycoming 0-320-E2D was now the way of the future for Cessna.

172K – Made throughout 1969 and 1970 the 172K was know as the start of long range fuel tanks. A popular option to add on during that time.

172L – In 1971 Cessna introduced the 172L which featured tubular landing gear.

172M – 73 through 76 Cessna introduced the “camber lift wing” more commonly know as a droop tip. Cessna also redesigned the instrument panel to allow for more avionics and instruments. Thus the standard “six pack” was born.

172N – The 172N was the first model to have “pre-selectable flaps” and even air condition was an upgradable option.

172P – In 1981 Cessna created the 172P a model meant to fix all the woes of previous models. 40 degrees of flaps were out, 30 degrees was the new thing. The landing light was moved from the nose to the wing to increase bulb life.

172R – Which is still in production today is powered by a 160 horsepower Lycoming IO-360L2A with new sound proofing, interior, and fuel injection the 172R has been a popular choice for pilots and flight schools.

172S – Boasting many of the same features as the 172R but the 172S offers the Garmin G-1000 package.

Choosing the right model can be a daunting and difficult process but after you have ironed out all of you needs you can know what to look for.

Part 3: What to look for?

    Looking for my 1st plane, I would like to take lessons and purchase the same type of plane, any advise.

    Hey Mike,

    172's are frequent trainers.

    Things to look for

    -Low Total time airframe (TTAF) under say 4,000 is a gem but don't overlook the 5-6 thousand range

    -Low overhaul time (SMOH) Most 172's have a lycoming 0-320 and the overhaul "max suggestion time" is 2000 hours. Look for something midlife or less.

    -IFR avionics. DO you wish to get you instrument one day? This will save a ton of money and stress having them installed already.

    There's a ton more email me and keep me up to date on your progress.
  • Jason, nice overview, but I'm afraid that you're poorly informed on at least a few points...

    1) the 172S is a 180hp, 2550 lb mtow version of the 172R (160hp, 2440 mtow).

    2) the six pack instrument panel predates the 1973 172M by at least two years, as my 1971 AA-1A has a six pack.

    Can the landing gear exhibit negative camber or does this mean the gear is sprung?
  • Ira,

    Great question!

    In 1971 Cessna introduced the 172L. The biggest change in this was the landing gear from a flat tapered steel spring (no camber) to tubular landing gear.
