The Piper PA-23 Apache and Aztec are twin-engine, high-wing, fixed-tricycle landing gear aircraft manufactured by Piper Aircraft from 1959 to 1981. These aircraft, known for their versatility and rugged construction, have enjoyed widespread use in various roles, including commercial air transport, corporate transportation, flight training, and personal use. The PA-23 designation encompasses several distinct models, each with unique features and capabilities. The Apache, originally marketed as the "Comanche," debuted in 1959, featuring a sleek fuselage and a powerful Lycoming engine configuration. The larger, six-seat Aztec arrived in 1962, offering increased payload and range, making it a popular choice for commercial operations. Both the Apache and Aztec models have been praised for their reliable performance, spacious cabins, and ease of maintenance. Their robust construction, proven over decades of service, has earned them a reputation for dependability and safety. The aircraft are known for their ability to handle a wide range of weather conditions and terrains, making them suitable for both short and long-distance flights. However, despite their legacy and enduring popularity, the PA-23 series has been discontinued, making access to comprehensive manuals, service parts information, and owner's guides crucial for maintaining these valuable aircraft. The digital availability of these resources, compiled into a convenient PDF format, ensures that owners, mechanics, and enthusiasts can readily access the information they need to keep their Apache and Aztec flying safely and efficiently.
