FS2004 Piper PA-23, named Apache and later Aztec, was the first twin-engine aircraft built by Piper Aircraft. Originally to be named the “Twin-Stinson” and designed as a four-seater low-wing all-metal monoplane with a twin tail, the prototype first flew 2 March 1952. Declining sales of the Apache prompted the redesign dubbed PA-23-250 Aztec, with 250 hp (186 kW) Lycoming. The first models where delivered with O-540 Lycoming carburetor engines. These first models came in a five-seat configuration which became available in 1959. The later models of the Aztec where equipped with IO-540 fuel-injected engines and six-seat capacity, and continued in production until 1982. There were also turbocharged versions of the later models, which were able to fly at higher altitudes. Created with FSDS2.10 by John B. Loney, Jr.
