The Savoia-Marchetti S.56 was an Italian single-engine biplane flying boat trainer and tourer, built by Savoia-Marchetti. Of unequal span, the upper longer than the lower,〔Donald 1997, p.820.〕 of wooden construction. Instructor and student sat side by side in separate cockpits, with dual controls; a third cockpit was located just aft that. It used a 52 kW (70 hp) Anzani. The S.56A had a slightly longer span and 60 kW (80 hp) Anzani, and turned into amphibians by addition of manually retractable landing gear. Private owners and flying clubs purchased at least 12,〔 and ''Regia Aeronautica'' operated four〔 (differing in engine specification, including 96 kW FIAT A.53, 101 kW FIAT A.54, and Walter Venus radial engines, among others). The S.56A proved popular in the U.S., and the American Aeronautical Corporation (AAC) set up licence production in 1929, relying on the 67 kW (90 hp) Kinner K5 radials for power for three two-place aircraft and over 40 three-seaters.〔 This was followed in 1930 by the S.56B, powered by the 93 kW (125 hp) Kinner B-5, with an enclosed cockpit. Another was converted to a single-seater and given additional fuel tanks, as the S.56C, for an attempted round-the-world flight by American businessman Smith Reynolds.〔 In 1932, the Budd Company built an all-metal S.56 as the Budd BB-1 ''Pioneer''. ==Operators== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Savoia-Marchetti S.56」の詳細全文を読む スポンサード リンク
