Design and development

Measured by its longevity and popularity, the Cessna 172 is the most successful mass produced light aircraft in history. The first production models were delivered in 1956 and they are still in production. As of 2008, more than 43,000 had been built. The Skyhawk's main competitors have been the Beechcraft Musketeer

 powered Cessna 170C with a larger elevator and more angular vertical tail. Although the variant was tested and certified, Cessna decided to modify it with a tricycle landing gear and the modified Cessna 170C flew again on 12 June 1955. To reduce the time and cost of certification the type was added on to the Cessna 170 type certificate as the Model 172. Later the 172 was given its own type certificate 3A12. The 172 became an overnight sales success and over 1,400 were built in 1956, its first full year of production.

Early 172s were similar in appearance to the 170, with the same straight aft fuselage and tall gear legs, although the 172 had a straight vertical tail while the 170 had a rounded fin and rudder. Later 172 versions incorporated revised landing gear and the sweptback tail which is still in use today. The final aesthetic development in the mid-1960s, was a lowered rear deck that allowed an aft window. Cessna advertised this added rear visibility as "Omni-Vision" . This airframe configuration has remained almost unchanged since then, except for updates in avionics

Operational history

On December 4, 1958 Robert Timm and John Cook took off from McCarran Airfield, Las Vegas, NV in N9172B. Sixty-four days, 22 hours, 19 minutes and 5 seconds later, they landed back at McCarran Airfield on February 4, 1959. The flight was part of a fund raising effort for the Damon Runyon

 Cancer Fund. Food and water were transferred by matching speeds with a chase car on a straight stretch of road in the desert, and hoisting the supplies aboard with a rope and bucket. Fuel was taken on by hoisting a hose from a fuel truck up to the aircraft, filling an auxiliary belly tank installed for the flight, pumping that fuel into the aircraft's regular tanks, and then filling the belly tank again. The drivers steered while a second person matched speeds with the aircraft with his foot on the vehicle's accelerator pedal.

Engine oil was added by means of a tube from the cabin that was fitted to pass through the firewall. Only the pilot's seat was installed. The remaining space was used for a pad on which the relief pilot slept. The right cabin door was replaced with an easy-opening, accordion-type door to allow supplies and fuel to be hoisted aboard. Early in the flight, the engine driven electric generator failed. A Champion wind driven generator (turned by a small propeller) was hoisted aboard, taped to the wing support strut, plugged into the cigarette lighter socket—and served as the aircraft's source of electricity for the rest of the flight. The pilots decided to end the marathon-flight because, with 1558 hours continuous running during the record-setting flight plus several hundred hours already on the engine beforehand (considerably in excess of its normal overhaul interval), the engine's power output had deteriorated to the point that they were barely able to climb away after refueling.

 145 hp six-cylinder, air-cooled engine and had a maximum gross weight of 2200 lb (998 kg). Introductory base price was USD$8995 and a total of 4195 were constructed over the five years.

172A
The 1960 model 172A introduced a swept back tail and rudder, as well as float fittings. The price was USD$9450 and 1015 were built.

172B
The 172B was introduced in late 1960 as the 1961 model and introduced a shorter undercarriage, engine mounts lengthened three inches (76 mm), a reshaped cowling and a pointed propeller spinner. For the first time, the "Skyhawk" name was applied to an available deluxe option package. This added optional equipment included full exterior paint to replace the standard partial paint stripes and standard avionics. The gross weight was increased to 2250 lb (1,021 kg).

172C
The 1962 model was the 172C. It brought to the line an optional autopilot and a key starter to replace the previous pull-starter. The seats were redesigned to be six-way adjustable. A child seat was made optional to allow two children to be carried in the baggage area. The 1962 price was USD$9895. A total of 889 172C models were produced.

172D
The 1963 172D model introduced the lower rear fuselage with wraparound Omni-Vision rear window and a one-piece windshield. New rudder and brake pedals were also added. 1146 172Ds were built.

1963 also saw the introduction of the 172D Powermatic. This was equipped with a Continental GO-300E

s. Gross weight was increased to 2300 lb (1,043 kg) where it would stay until the 172P. The 172E also featured a re-designed instrument panel. 1401 172Es were built that year as production continued to increase.

172F
The 1965 model 172F introduced electrically operated flaps to replace the previous lever-operated system. It was built in France by Reims Cessna as the F172 until 1971. These models formed the basis for the US Air Force's T-41A Mescalero primary trainer.

A total of 1436 172Fs were completed.

172G
The 1966 model year 172G introduced a more pointed spinner and sold for USD$12,450 in its basic 172 version and USD$13,300 in the upgraded Skyhawk version. 1597 were built.

 to reduce drag and improve the appearance of the aircraft in flight. A new cowling was used, introducing shock-mounts that transmitted lower noise-levels to the cockpit and reduced cowl cracking. The electric stall warning horn was replaced by a pneumatic one.

The 1967 model 172H sold for USD$10,950 while the Skyhawk version was USD$12,750. 839 were built that year, representing the first year that production was less than the year before.

172I

The 1968 model marked the beginning of the Lycoming

 engine of 150 hp, an increase of 5 hp over the Continental powerplant. The increased power resulted in an increase in optimal cruise from 130 mi/h TAS to 131 mi/h TAS. There was no change in the sea level rate of climb at 645 ft (197 m) per minute.

The 172I also introduced the first standard "T" instrument arrangement. The 172I saw an increase in production to record levels with 1206 built.

172J
The Cessna Company planned to drop the previous 172 configuration for the 1968 model year and replace it with a cantilever-wing/stabilator configuration that would be the 172J. However, as time for model introduction neared, those dealers who were aware of the change began applying pressure on the factory to continue the previous configuration. They felt the new model would be less usable as a trainer. Consequently, and at the last minute, the decision was made to continue the 172 in its original configuration. The planned 172J configuration would be introduced as a new model, the 177. The deluxe option would become the 177 Cardinal

. The "J" designation was never publicly used.

172K
The next model year was the 1969 "K" model. The 1969 172K had a redesigned vertical fin cap and reshaped rear windows. Optional long range 52 US gal (197 l) wing fuel tanks were offered. The rear windows were slightly enlarged by 16 in2. The 1969 model sold for USD$12,500 for the 172 and USD$13,995 for the Skyhawk, with 1170 made.

The 1970 model was still called the 172K but sported fiberglass, downward-shaped, conical wing tip

s. Fully articulated seats were offered as well. Production in 1970 was 759 units.

172L
The 172L, sold during 1971 and 1972, replaced the main landing gear legs (which were originally flat spring steel) with tapered, tubular steel gear legs. The new gear had a width that was increased by 12 in (30 cm). The new tubular gear was lighter, but required aerodynamic fairings to maintain the same speed and climb performance as experienced with the flat steel design. The "L" also had a plastic fairing between the dorsal fin and vertical fin to introduce a greater family resemblance to the 182

's vertical fin.

The 1971 model sold for USD$13,425 in the 172 version and USD$14,995 in the Skyhawk version. 827 172Ls were sold in 1971 and 984 in 1972.

172M
The 172M of 1973–76 gained a drooped wing leading edge for improved low speed handling. This was marketed as the "camber-lift" wing.

The 1974 172M was also the first to introduce the optional 'II' package which offered higher standard equipment, including a second nav/comm radio, an ADF and transponder
Transponder (aviation)

. The baggage compartment was increased in size and nose-mounted dual landing lights were available as an option.

The 1975 model 172M sold for USD$16,055 for the 172, USD$17,890 for the Skyhawk and USD$20,335 for the Skyhawk II.

In 1976, Cessna stopped marketing the aircraft as the 172 and began exclusively using the "Skyhawk" designation. This model year also saw a redesigned instrument panel to hold more avionics. Among other changes, the fuel and other small gauges are relocated to the left side for improved pilot readability compared with the earlier 172 panel designs. Total production of "M" models was 7306 over the four years it was manufactured.

172N
The Skyhawk N, or Skyhawk/100 as Cessna termed it, was introduced for the 1977 model year. The "100" designation indicated that it was powered by a Lycoming O-320-H2AD, 160 hp engine designed to run on 100 octane fuel, whereas all previous engines used 80/87 fuel. Unfortunately, this engine proved troublesome and it was replaced by the similarly rated O-320-D2J to create the 1981 172P.

The 1977 "N" model 172 also introduced rudder trim as an option and standard "pre-selectable" flaps. The price was USD$22,300, with the Skyhawk/100 II selling for USD$29,950.

The 1978 model brought a 28-volt electrical system to replace the previous 14-volt system. Air conditioning was an option.

The 1979 model "N" increased the flap extension speed for the first 10 degrees to 115 knots (225 km/h). Larger wing tanks increased the optional fuel to 66 gallons (250 l).

The "N" remained in production until 1980 when the 172P or Skyhawk P was introduced.

172O
There was no "O" ("Oscar") model 172.

172P
The 172P, or Skyhawk P, was introduced in 1981 to solve the reliability problems of the "N" engine. The Lycoming O-320-D2J

 was a great improvement.

The "P" model also saw the maximum flap deflection decreased from 40 degrees to 30 to allow a gross weight increase from 2300 lb (1,043 kg) to 2400 lb (1,089 kg). A wet wing was optional, with a capacity of 62 US gallons of fuel.

The price of a new Skyhawk P was USD$33,950, with the Skyhawk P II costing USD$37,810 and the Nav/Pac equipped Skyhawk P II selling for USD$42,460.

In 1982, the "P" saw the landing lights moved from the nose to the wing to increase bulb life. The 1983 model added some minor sound-proofing improvements and thicker windows.

A second door latch pin was introduced in 1984.

Production of the "P" ended in 1986 and no more 172s were built for eleven years as legal liability rulings in the USA had pushed Cessna's insurance costs too high, resulting in dramatically increasing prices for new aircraft.

There were only 195 172s built in 1984, a rate of fewer than 4 per week.

172Q Cutlass
The 172Q was introduced in 1983 and given the name Cutlass to create an affiliation with the 172RG, although it was actually a 172P with a Lycoming O-360-A4N engine of 180 hp. The aircraft had a gross weight of 2550 lb (1,157 kg) and an optimal cruise speed of 122 knots (239 km/h) compared to the 172P's cruise speed of 120 knots (235 km/h) on 20 hp less. It had a useful load that was about 100 lb (45 kg) more than the Skyhawk P and a rate of climb that was actually 20 feet (6 m) per minute lower, due to the higher gross weight. Production ended after only three years when all 172 production stopped.

172R
The Skyhawk R was introduced in 1996 and is powered by a derated Lycoming IO-360-L2A producing a maximum of 160 hp at just 2,400 rpm. This is the first Cessna 172 to have a factory fitted fuel-injected engine.

The 172R's maximum takeoff weight is 2450 lb (1,111 kg). This model year introduced many improvements, including a new interior with soundproofing, an all new multi-level ventilation system, a standard four point intercom, contoured, energy absorbing, 26g front seats with vertical and reclining adjustments and inertia reel harnesses.

172S

The Cessna 172S was introduced in 1998 and is powered by a Lycoming IO-360-L2A producing 180 hp. The maximum engine rpm was increased from 2,400 rpm to 2,700 rpm resulting in a 20 hp increase over the "R" model. As a result, the maximum takeoff weight was increased to 2550 lb (1,157 kg). This model is marketed under the name Skyhawk SP, although the Type Certification data sheet specifies it is a 172S.

The 172S is built primarily for the private owner-operator and is, in its later years, offered with the Garmin G1000

 avionics package and leather seats as standard equipment.

As of 2009, only the S model is in production.

Cessna 172RG Cutlass
Cessna introduced a retractable-gear version of the 172 in 1980 and named it the Cutlass 172RG.

The Cutlass featured a variable pitch, constant speed propeller and more powerful Lycoming O-360-F1A6 engine of 180 hp. The 172RG sold for about USD$19,000 more than the standard 172 of the same year and produced an optimal cruise speed of 140 knots (260 km/h), compared to 122 knots (239.1 km/h) for the contemporary 160 hp version.

The 172RG did not find wide acceptance in the personal aircraft market, but was adopted by many flight schools as a complex aircraft trainer. Between 1980 and 1984 1177 RGs were built, with a small number following before production ceased in 1985.

While numbered and marketed as a 172, the 172RG was actually certified on the Cessna 175

) derated to 195 hp with a two bladed, constant speed propeller. The Hawk XP was capable of a 131 knots (256.7 km/h) cruise speed.

Owners claimed that the increased performance of the "XP" didn't compensate for its increased purchase price and the higher operating costs associated with the larger engine. The aircraft was well-accepted for use on floats, however, as the standard 172 is not a strong floatplane, even with only two people on board, while the XP's extra power improves water take-off performance dramatically.

 under an STC. The new model was designated the 172 Skyhawk TD, indicating "Turbo Diesel".

In early 2008 certification had been planned for the summer of 2008 and Cessna had forecast delivering about 125 TDs before the end of 2008. The TD was intended to sell for about USD$15,000 more than the top of the line "SP" Skyhawk and $35,000 more than the "R". Early orders for the TD were strong with most of the demand from flight schools and non-US operators. In April 2008 the 172TD's engine manufacturer, Thielert

 filed for insolvency under German law, throwing the future of the aircraft into doubt. On May 1, 2008 Cessna announced that they had cancelled all 2008 deliveries of the 172TD due to the insolvency of Thielert. The company stated: "At this point we have decided that we will not deliver 172TD aircraft during 2008, and we have informed our customers accordingly." Cessna has indicated that they still wish to produce a diesel 172 as market demand is strong for this aircraft with over 100 orders.
