Cessna Model Histories
Each model is broken down by year with information such as serial numbers, base price and gross weight. The histories will give you information on updates made, such as in 1965 the 172 flaps were changed from manual to electric. Also, in 1977 the 182Q engine was changed from the 0-470-S to the 0-470-U. The primary purpose of this change was to reduce noise but the rate of climb also increased. This information can be beneficial if you’re looking to purchase a Cessna aircraft.
