Piper Aerostar: A High-Performance Twin-Engine Aircraft
The Piper Aerostar is one of the fastest piston-powered twin-engine aircraft ever built. Originally designed by Ted Smith in the late 1960s, the Aerostar was created to be a high-speed, high-performance aircraft with unmatched efficiency and handling in its class. The aircraft went through several ownership changes, eventually being acquired by Piper Aircraft in the late 1970s, leading to the name Piper Aerostar.
This article explores the history, design, technical specifications, and performance of the Piper Aerostar, a true icon in general aviation.
History and Development
Origins of the Aerostar
The Aerostar 600 series was initially developed by Ted Smith Aircraft Company, a firm founded by aviation engineer Ted R. Smith, who had previously designed the Aero Commander. Smith’s goal was to build the fastest, most efficient piston twin aircraft ever created.
The first model, the Aerostar 600, flew in 1967, and subsequent models introduced more powerful engines and turbocharging for even better performance.
Piper’s Involvement
In 1978, the design was acquired by Piper Aircraft, which continued production and marketing under the Piper Aerostar brand. However, Piper eventually discontinued production in 1984, making the Piper Aerostar a sought-after aircraft on the used market today.
