The Kreutzer Air Coach is an American-built light trimotor transport aircraft of the late 1920s. ==Design and development== Joseph Kreutzer formed the company of the same name in Los Angeles in late 1928. In 1929 the firm moved to Clover Field, Santa Monica, California, occupying the former Bach aircraft factory. Kreutzer was joined by Lawrence Brown and Albin Peterson who had designed the Brown-Mercury C-2.〔"(Data and information on the Air Coach series )", ''Aerofiles''. Retrieved 22 September 2010.〕 Kreutzer developed a series of small high-winged trimotor light transport aircraft, naming each the Air Coach. Each had a fixed tailwheel undercarriage with the two outboard engined slung from the supporting bracing struts to the high wing. The first model was the K-1 Air Coach of late 1928 which was powered by three Velie engines and accommodated four persons. The sole example ''NX71E'' first flew on 5 December 1928. It was later fitted with a single J6-9 engine and a hopper for agricultural purposes. It crashed at Yuba City California in 1936.〔 The next Air Coach was the K-2 of 1929 which had a similar wing span but was lengthened by five feet to permit six persons to be carried. The K-2 was fitted with one and two LeBlond engines. Four examples were built. The K-3 was similar to the K-2 but was fitted with three LeBlond engines. Two were built and two earlier machines converted to this standard. The K-4 designation was not used.〔 The K-5 Air Coach, also of 1929, had similar dimensions to the K-2 and K-3 but was fitted with three five-cylinder Kinner K-5 engines. The extra power enabled heavier loads to be carried and in addition to eight new-build aircraft, one earlier aircraft was converted to this standard.〔 Kreutzer's operations were suspended in 1931 and no further development was undertaken. The firm was reorganized as the Air Transport Manufacturing Co in 1935 and a T-6 design was developed, but no production materialised.〔 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「Kreutzer Air Coach」の詳細全文を読む スポンサード リンク
