The Cessna 401 and 402 are twin-engine, high-wing, fixed-wing aircraft designed and manufactured by Cessna Aircraft Company starting in the late 1960s. These aircraft were primarily designed for the corporate and commercial markets, providing reliable and versatile platforms for a variety of purposes. The Cessna 401, introduced in 1967, was the first of the series, featuring two Continental TSIO-520-A engines producing 310 horsepower each. The 402, introduced in 1969, was a stretched version of the 401, offering increased seating capacity and cargo space. Both models were known for their robust construction, dependable performance, and easy handling characteristics. They became popular choices for air taxi operations, cargo transportation, and executive transport, with many finding application in remote areas and challenging environments. The Cessna 401 and 402 were produced for over a decade, with several updates and refinements implemented throughout their production run. The most notable change was the introduction of the 402B model in 1973, which featured the more powerful Continental TSIO-520-C engines producing 350 horsepower each, boosting the aircraft's performance and payload capabilities. The Cessna 401 and 402 were known for their reliability and durability, establishing a strong reputation in the general aviation industry. Despite being discontinued in the late 1970s, these aircraft remain popular choices for various purposes, with a significant number continuing to operate today, thanks to their rugged construction, adaptable design, and relatively low operating costs.
