About the CESSNA S550

The Cessna S550 Citation S/II is a highly-regarded entry in the iconic Citation business jet series, designed and produced by the Cessna Aircraft Company. This aircraft was developed as an upgraded version of the Citation II, emphasizing improvements in performance, efficiency, and passenger comfort. The S550, often referred to simply as the Citation S/II, took to the skies for the first time in 1984 and remained in production until 1994. Its design addressed the growing demands of business travelers and charter operators who sought a cost-effective, reliable, and versatile jet for short- to mid-range flights.

One of the key motivations behind the development of the S550 was to create an aircraft that could offer better fuel efficiency and enhanced aerodynamic performance compared to its predecessor. Engineers at Cessna incorporated a host of refinements, including a redesigned wing with increased span and more efficient aerodynamics, which contributed to improved overall performance. The S550 also featured upgraded engines, specifically the Pratt & Whitney JT15D-4B turbofans, which provided better thrust and fuel economy.

Key Features and Capabilities

The Citation S/II quickly found its niche in the business aviation market, offering a compelling blend of operational efficiency, low operating costs, and the ability to operate from shorter runways. Its cabin was designed to comfortably accommodate up to eight passengers, featuring a well-appointed interior that included executive seating, a private lavatory, and often, a refreshment center. This made it an attractive option for corporate executives, small business owners, and private individuals who needed a reliable means of transport for business and personal travel.

Over its production run, the Cessna S550 Citation S/II garnered a reputation for its durability, ease of maintenance, and solid performance, ensuring its status as a beloved member of the Citation family. Its continued use in various roles within general aviation highlights the lasting impact and legacy of this versatile business jet.
