Now that you know what to expect from the current Cessna 172 model, let’s take a look at the 172’s history and discover 10 must-know pieces of information about this aircraft.
1. The Cessna 172 is the most-produced aircraft ever
Since production began in 1956, over 43,000 Cessna 172s have been built with more still on the way. This legendary aircraft is well-loved, well-respected and still in demand more than sixty years after it first came on the market.
2. There have been over 20 variations of the Cessna 172 (plus some special versions)
Over the course of its long life, the Cessna 172 has naturally undergone a series of modifications, upgrades and enhancements while remaining true to the heart of her original solid design.
Among the most notable are the 172B which introduced the Skyhawk name, the 172D with its Omni-Vision rear wraparound window, and the 172S which incorporated Garmin G1000.
3. Not all Cessna 172s were built in America
It is known as an American aircraft, but you may be surprised to learn that 1,436 Cessna 172s were actually built in France. From 1965-1971, Reims Cessna constructed the Cessna 172F. This model replaced a lever-operated flap system with electric flaps. It was also the basis for the U.S. Air Force’s T-41A Mescalero – a primary trainer.
4. The “Skyhawk” name originally referred to a deluxe option package
Although you may be used to hearing the name “Cessna Skyhawk,” originally, the Cessna 172 was called just that – the Cessna 172. It had no fancy name. The name Skyhawk came about in 1960 with the release of the 172B. This model had the option for a standard package or a deluxe option package – named the Skyhawk – with extra equipment and full exterior paint. Eventually the name stuck and came to refer to the entire Cessna 172 line-up.
5. The 172’s tricycle landing gear design helps you ace your landings
One of the key design features of the 172 lineup has always been the tricycle landing gear design. This design was tested out on the WWII B-24, B-25 and B-26 bombers. The combination of a nosewheel in the front and moving the main wheels aft was found to make a tricycle landing gear aircraft easier to land.
In this configuration, the center of gravity (COG) is in front of the main wheels. What this means to you is that when you land in a tricycle gear aircraft, if you are crooked, the airplane’s weight will help to straighten you out. By contrast, a conventional landing gear setup has a center of gravity that is aft of the main wheels. Land crooked in this type of aircraft, and your mistake will just get exacerbated by the influence of the aircraft’s weight.
6. Cessna 172s are used as trainer aircraft for many flight schools
If you have a private pilot’s license, odds are that you trained on a 172 at some point. Flight schools love this aircraft for several reasons. The ease of flying a tricycle landing gear configuration is a main selling point as are the forgiving handling characteristics and increased visibility of the high wing design plus rear “Omni-Vision” window.
In fact, the 172 is so stable that its built-in aerodynamic stability can often return a plane to straight and level flight after a spin even without input from the pilot.
7. The world record for the longest endurance flight is held by a Cessna 172
Imagine what it would be like for a small aircraft to fly non-stop for over 64 days. Bob Timm and John Cook did just that from December of 1958 to February of 1959. Their 64-day, 22-hour, 19-minute flight out of Las Vegas still holds the endurance record.
Timm and Cook flew a modified Cessna 172 which was named The Hacienda after the Hacienda Hotel who sponsored the $100,000 flight as a combined publicity stunt and fundraiser for cancer research.
To prepare for the flight, the team added a 95-gallon belly fuel tank to augment the 47 gallons carried in the wing tanks. An electric pump in the belly tank allowed fuel to be pumped into the wing tanks for refueling. Oil lines were replumbed to allow inflight oil and oil filter changes. In the cabin, the pilot seat stayed, but everything else was removed and a 4’x4’x4” foam pad was added as a bed for the off-duty pilot. An added platform off the co-pilot side allowed for better footing during refueling. A small sink in the rear was used for washing and shaving.
An FAA waiver allowed the overweight aircraft to operate at 350-400 pounds over the normal limit. Twice a day the Hacienda would rendezvous with a Ford truck over a straight stretch of closed off highway. Flying 20 feet above the ground, the Hacienda used an electric winch to hook a refueling hose from the truck. Three minutes later with its belly tank full, the Hacienda would release the hose and continue her flight.
The next time you pass through the Las Vegas McCarren Airport’s baggage claim area, look up – the Hacienda is hanging from the ceiling at the airport where her historic flight began and ended.
8. There was (briefly) a diesel-powered Skyhawk on the market
Given the lower cost of Jet A and its more readily accessible nature overseas, Cessna decided to release a diesel version of the Skyhawk in 2017. The Turbo Skyhawk JT-A came powered by a Continental CD-155 diesel engine and received high marks in fuel efficiency and power.
Unfortunately, the diesel engine also resulted in a higher purchase price ($420,000 compared to $307,000 for the 172S) and reduced payload capacity because of the added weight. Just 11 months after receiving FAA certification, the JT-A was discontinued due to poor sales.
9. The triangle gear Skyhawk almost didn’t happen
Rumor has it that when a group of Cessna engineers approached the Cessna marketing department with their idea for a triangle gear aircraft, they were shot down. Marketing wanted to focus on tailwheel aircraft. Thankfully for Cessna and for all of us, the engineers were undaunted, and they continued work to build out the first concept version of the tricycle-geared Cessna 172 that we all know and love. Ultimately it met with approval and went into production.
10. The Cessna 172 can be powered electrically (at least as a proof-of-concept)
Electric Skyhawks may be in our future. In 2012, Cessna and Beyond Aviation worked together to develop an electrically powered variation of the Cessna 172. The aircraft took multiple successful test flights powered by the Panacis batteries that take the place of the back seats. One of the big advantages of an electric aircraft would be imperviousness to density altitude changes.
Bonus: Answers to Frequently Asked Questions
Finally, we have rounded up the answers to some of the most frequently asked Cessna 172 questions.
1. How safe is the Cessna 172 compared to other aircraft?
The 172 has an impressive safety record, especially when compared to the industry average. Statistically, the Cessna 172’s fatal accident rate is .56 per 100,000 hours. This is about half of the industry average rate of 1.2-1.4.
2. How much does it cost to own and operate a Cessna 172?
Cost is an important consideration for most pilots when they are contemplating the purchase of an aircraft. Beyond the purchase price, you must also account for operational costs, storage, insurance, maintenance and more. AOPA crunched the numbers for you and put together a hypothetical operating cost calculation for a Cessna Skyhawk
This particular calculation was based on a 1975 Cessna 172M with a purchase price of $39,000. For comparison, the purchase price of a new Cessna 172S is around $307,000.
Loan payments in the AOPA scenario were calculated at $290 for a $35,000 loan over 20 years at 7.9%. AOPA insurance payments came to $1200 a year, and hangar space rental was $250 a month, which equates to $3000 a year.
Yearly maintenance was estimated to be $2500 or $25/hr. for flying 100 hours or $4000 ($13.34/hr.) over 300 yearly hours.
The final factor to consider is any kind of projects you want to do, especially to an older aircraft.
The final AOPA estimate comes out to $108.10 per hour if flying 300 hours a year or $225.30/hr. for 100 flight hours.
The total annual cost is around $22,530 for 100 yearly hours of flight and $32,430 for 300 hours.
That said, keep in mind that you can save money by opting for tie-downs rather than hangars, and hangar costs vary by location. The amount you owe on your aircraft loan (should you need to take one out) is also an important variable component of this calculation.
3. What kind of engine does the 172 have?
The original 1955 Cessna 172 was powered by a Continental O-300 145 hp engine. In 1968, the 172I debuted the Lycoming O-320-E2D 150 hp engine. Previous engines had used 80/87 fuel, but the 1977 Skyhawk N (172N) tried out a Lycoming O-320-H2AD 160 hp engine running on 100-octane. The performance wasn’t favorable, so starting in 1981, the 172P switched to the Lycoming O-320-D2J.
Factory-fitted fuel-injected engines arrived with the 1996 172R’s Lycoming 160 hp Lycoming IO-360-L2A. The current 172S model was introduced in 1998 with an upgraded 180 hp Lycoming IO-360-L2A.
4. When will Cessna release a new model of the 172?
Cessna has been exploring both diesel and electric options, but for now, the 172S is the only Skyhawk on the market.
The Cessna 172 is a classic plane with a long and storied history. Dig into its past and you will find a series of well-loved, reliable, safe aircraft that are easy and enjoyable to fly. Memorize some of our top 10 facts and soon you will soon be more well-versed on the 172 than your fellow pilot friends.
