The Piper PA-23 Apache, more commonly known as the Aztec, is a six- to eight-seat twin-engine, high-wing, fixed-tricycle landing gear utility aircraft that was produced by Piper Aircraft from 1962 to 1985. The PA-23 offered a significant step up in performance and capacity compared to Piper's previous single-engined aircraft, like the Cherokee. The Aztec was designed to be a versatile aircraft suitable for a variety of uses, including commercial operations, private flying, and even aerial photography. The PA-23-160, PA-23-150, and PA-23-235 models are all variants of the Aztec, distinguished mainly by their engine choices. The PA-23-160 was the original version, powered by two Lycoming IO-360 engines, while the PA-23-150 featured more powerful Lycoming IO-540 engines. The PA-23-235 was a later model that incorporated many enhancements and featured upgraded avionics, including a glass cockpit option.

The Aztec's popularity is attributed to its spacious cabin, capable performance, and robust construction. While not as fast as some contemporary turboprop aircraft, the PA-23 excels at short-field operations, thanks to its powerful engines and high-wing design. The aircraft features a fixed tricycle landing gear, which provides excellent ground handling characteristics, making it suitable for a variety of landing surfaces. The Aztec's versatility is also highlighted by its optional cargo door, allowing for easy loading and unloading of larger items. The PA-23 Apache remains a popular choice today, especially for businesses and private owners who need a reliable, spacious, and capable aircraft for both passenger and cargo transport. However, like any aging aircraft, the Aztec requires meticulous maintenance and careful attention to its service parts, as outlined in the PA-23 Apache Aztec Aircraft Service Parts Owners Manual.
