172H
The 1967 model 172H was the last [Vous devez être inscrit et connecté pour voir ce lien] powered model.
It also introduced a shorter-stroke nose gear oleo 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 [Vous devez être inscrit et connecté pour voir ce lien]$10,950 while the Skyhawk version was [Vous devez être inscrit et connecté pour voir ce lien]$12,750. 839 were built that year, representing the first year that production was less than the year before.[Vous devez être inscrit et connecté pour voir ce lien]

172I
The 1968 model marked the beginning of the [Vous devez être inscrit et connecté pour voir ce lien] powered 172s.
The familiar 172 needed to be re-engined because Cessna had cancelled its contract with Continental for their venerable 0-300 6-cyl engine of 145 hp (108 kW).
The "I" model was introduced with a [Vous devez être inscrit et connecté pour voir ce lien] engine of 150 hp (112 kW), an increase of 5 hp (3.7 kW) over the Continental powerplant.
The increased power resulted in an increase in optimal cruise from 130 mph (209 km/h) TAS to 131 mph (211 km/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 [Vous devez être inscrit et connecté pour voir ce lien].
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 square inches (103 cm2).
The 1969 model sold for [Vous devez être inscrit et connecté pour voir ce lien]$12,500 for the 172 and [Vous devez être inscrit et connecté pour voir ce lien]$13,995 for the Skyhawk, with 1170 made.
[Vous devez être inscrit et connecté pour voir ce lien]
The 1970 model was still called the 172K but sported fiberglass, downward-shaped, conical [Vous devez être inscrit et connecté pour voir ce lien]. 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, 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).
[Vous devez être inscrit et connecté pour voir ce lien][Vous devez être inscrit et connecté pour voir ce lien]
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 [Vous devez être inscrit et connecté pour voir ce lien]'s vertical fin.
The 1971 model sold for [Vous devez être inscrit et connecté pour voir ce lien]$13,425 in the 172 version and [Vous devez être inscrit et connecté pour voir ce lien]$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 [Vous devez être inscrit et connecté pour voir ce lien].

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 horsepower (119 kW) 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 [Vous devez être inscrit et connecté pour voir ce lien]$22,300, with the Skyhawk/100 II selling for [Vous devez être inscrit et connecté pour voir ce lien]$29,950.[Vous devez être inscrit et connecté pour voir ce lien]
