Piper PA-28 Cherokee is a family of light aircraft designed for flight training, air taxi and personal use, built by Piper Aircraft.

All members of the PA-28 family are all-metal, unpressurized, four-seat, single-engine piston-powered (piston engine) airplanes with low-mounted wings and tricycle landing gear. All PA-28 aircraft have a single door on the co-pilot side, which is entered by stepping on the wing.

The first PA-28 received its type certificate from the FAA (Federal Aviation Administration) in 1960 (1960 in aviation) and the series remains in production in 2009. Current models are the Arrow and Warrior III. The Archer was discontinued in 2009, but with investment from new Piper owners Imprimis, will be revived in 2010.

Competition for the PA-28 series include the Cessna 172, the Grumman American AA-5 series (Grumman American AA-5) and the Beechcraft Musketeer. Piper has created variations within the Cherokee family by installing engines ranging from 140 to 300 hp (105-220 kW), providing turbocharging (turbocharger), offering fixed or retractable landing gear, fixed-pitch or constant speed propellers, and stretching the fuselage to accommodate 6 people. The larger, six-seat variant of the PA-28 is generally the PA-32; earlier versions were known as the "Cherokee Six," and a PA-32 version is still in production today under the model name Saratoga.
