Historical Note
The SIAI-Marchetti S.205 was designed in the mid-1960s as a versatile four-seat touring aircraft for both civil and military training markets. Manufactured at Sesto Calende on Lago Maggiore, the S.205 family was distinguished by its all-metal airframe, NACA 63-series laminar flow airfoil (root: 632618; tip: 632415), and a range of engine and undercarriage configurations. Variants included the S.205-18/F and 18/R (180 hp Lycoming O-360), the S.205-20/F and 20/R (200 hp Lycoming IO-360-A1A), and the S.205-22/R (220 hp Franklin 6A-350-C1). The S.208 represented the definitive development with a 260 hp Lycoming IO-540 engine and was adopted by the Italian Air Force as a liaison and training aircraft. Approximately 620 S.205 and 120 S.208 units were built. The type holds FAA Type Certificate A9EU and remains airworthy in private hands across Europe and North America.
