The PA-28 family of aircraft comprises all-metal, unpressurized, single-engined, piston-powered airplanes with low-mounted wings and tricycle landing gear. They have a single door on the right side, which is entered by stepping on the wing. The first PA-28 received its type certificate from the Federal Aviation Administration in 1960 and the series remains in production to this day. Current models are the Warrior, Arrow, and Archer TX and LX, and the Pilot 100 and i100. The Archer was discontinued in 2009, but with investment from new company ownership, the model was put back into production in 2010. Piper has created variations within the Cherokee family by installing engines ranging from 140 to 300 hp (105–220 kW), offering turbocharging, retractable landing gear, constant-speed propellers and stretching the fuselage to accommodate six people. The Piper PA-32 (initially known as "Cherokee Six") is a larger, six-seat variant of the PA-28. The PA-32R Saratoga variant was in production until 2009.
