PA-23

The PA-23 is a foundational twin-engined light piston utility aircraft, originally developed as the Twin Stinson in the 1950s. Piper Aircraft, the manufacturer, took over the design and launched it as the Apache. The first flight was in 1952, and production began in 1954. The initial Apache model featured two 150 hp Lycoming O-320 engines, followed by the Apache 160 with upgraded 160 hp engines.

Piper Aircraft has a long history, becoming a major U.S. manufacturer of general aviation aircraft. In 1959, the PA-23 design evolved into the more powerful PA-23-250 Aztec, featuring 250 hp Lycoming O-540 engines and a swept vertical tail. Production of the PA-23 line continued until 1981, with nearly 7,000 units built across all variants (Apache and Aztec). The aircraft remains a popular model known for its sturdy and reliable twin-engine design.

Maintenance access for this aircraft requires specialized platforms and stands. A variety of access solutions are utilized to support thorough inspection and service across all critical sections, including the Nose Section (radome, antenna, avionics, and cockpit), the Forward Fuselage (doors, cargo, and lighting systems), and the Wing & Engine Pylon sections. Platforms also facilitate access to the Landing Gear, Middle Fuselage, AFT Fuselage, and Tail Section.
