H./GHT International, 23 November 1967 867 NAMC Nihon Aeroplane Manufacturing Company Ltd, Toranomon Daiichi Building, No 1 Kotohira-cho, Shiba Minato-ku, Tokyo, Japan. YS11 There has been a marked revival in the fortunes of the NAMC YS-11 during the past year, following the announcement of the improved version and in the light of successful operating experience. Largest of all twin-turboprop feederliners (and the only aircraft designed from scratch for the most powerful version of the ubiquitous Rolls-Royce Dart), the YS-11 has been used by several Japanese carriers since April 1965, and during the past twelve- month three airlines outside Japan (Hawaiian, LANSA and Cruzeiro) have joined the ranks of users now flying a total of some 42 YS-lls. This operational experience has been a valuable sales point for the YS-11 A—the developed version announced last year and subject of recent intensive world-wide campaigns that have included demonstration tours of North and South America. The most important commercial success so far was announced early this month: the sale of ten YS-lls to Piedmont Airlines. Faced with a booming sales potential, NAMC is stepping up production. With the support of the Japanese Government, output will shortly be raised to two aircraft per month, then to three per month, and finally to five per month by next year. NAMC is committed to building ten YS-lls by the end of 1969. The manufacture of the YS-11 was first proposed by the Japanese Ministry of International Trade and Industry in 1956. The Trans- port Aircraft Development Association (TADA) was established in 1957 to run the project, and was superseded by NAMC in June 1959. Manufacture of the YS-11 is divided between six private companies: Mitsubishi Heavy Industries Ltd, Kawasaki Aircraft Co Ltd, Fuji Heavy Industries Ltd, Shin Meiwa Industry Co Ltd, Japan Aircraft Manufacturing Co Ltd and Showa Aircraft Industry Co Ltd. NAMC retains overall responsibility. The newly developing YS-11 A is offered in three versions: the Series 200 for all-passenger work; the Series 300 mixed-traffic version with a 98in x 72in side door towards the front of the cabin; and the Series 400 all-freighter, with a 120in x 72in door on the port side aft. All versions of the YS-11 A have the same kind of engine and overall dimensions as the original YS-11, but the maximum permitted operating weights have been increased following a strengthening of the wing structure. The first Series 200 is due to fly this month, and the first Series 300 next June.
