A brief history of Cessna C-172 Skyhawk aircraft: The Cessna factory first flew the prototype C-172 in 1955. The C-172 was a development of an earlier aircraft, the C-170, and initially the only difference between the two models was the nose landing gear and new angled tail surfaces of the C-172. The first cosmetic changes to appear on the new model were introduced in 1960 when the angled fin was replaced with a stylish new one with a sweep back. The next big change in the appearance of the aircraft came in 1963 when the fuselage behind the passenger cabin was lowered and wrap around windows introduced. The Cessna sales material from the time refers to this as the Omini Vision version! So, from 1963 onwards, the Skyhawk had got to the looks that are still present today. From the start of production until 1967, the Skyhawk was powered by the Continental 0-300 engine. The model produced for the first time in 1967 had the Lycoming 0-320 as power plant, and since then all Skyhawks have used Lycomings of various horsepower as power plants. From 1977 to 1981 Cessna produced a version of the Skyhawk, called C-172K Hawk XP. If had a Continental IO-360 engine with 195 hp and a constant speed two bladed prop. It was often uses with floats, as it was so much more powerful that the standard models. The Skyhawk was produced by Cessna until 1985, when prodution was stopped due to legal liability rulings in the US where relatives of people injured or killed in Cessna products could sue the company for high amounts of money. The production line was restarted in 1996 after a change in American law which severely reduced the liability of the manufacturer of light aircraft. The Cessna Skyhawk is still in production when this is written. The Skyhawk has enjoyed a tremendous popularity since it was first introduced. To date about 43.000 examples have been built, making it the greatest produced aircraft of all time. For interest, it might be worth mentioning the second and third place for the most produced aircraft of all time, but both of these come from the former Soviet Union. In second place is the Polikarpov PO-2 biplane which was produced in approximately 40.000 examples. In third place is the Ilyushin Il-2 Shturmovik which was produced in 36.000 examples. The Skyhawk has proven very popular with Icelandic pilots, and the first Skyhawk was imported new in 1957 getting the registration TF-BOB. Since then 58 Skyhawks have been registered in Iceland. |
