Piper PA-27 Aztec

Aztec 260


Basically an improved Apache, the Aztec was a full six-seater and had more powerful engines (250 hp) than the Apache. The first models were later named Aztec A. A major change came in 1962 with the introduction of the Aztec B, which had a lengthened nose giving the Aztec a completely different look from its Apache fore-runner. Improvements were made year by year and the models were given letters until 1976 when the Aztec F was marketed. By then the Aztec had longer “tiger shark” shaped engine nacelles and an even longer and sharper nose. When production ceased in 1981 a total of 4929 Aztecs had been built.
