NAMC YS-11

The only Japanese airliner to enter production since the 1940s, the YS11 was produced by NAMC (Nihon Aircraft Manufacturing Company), a consortium of Fuji, Kawasaki, Mitsubishi, Nippi, Shin Meiwa (now Shin Maywa) and Showa. NAMC designed the YS-11 as a short to medium range airliner, with particular attention being paid to meeting the specific requirements of Japanese domestic airlines.

Fuji was given responsibility for the tail unit, Kawasaki the wings and engine nacelles, Mitsubishi the forward fuselage and final assembly, Nippi the ailerons and flaps, Shin Meiwa the rear fuselage and Showa the light alloy honeycomb structural components. The YS-11 entered service with TDA (Toa Domestic Airlines - now JAS) in April 1965.

Initial production was of the YS11-100. Later derivatives included the YS11-A200 for export markets, featuring an increased max takeoff weight; the YS11-A300, a combi passenger/freight model; and the YS11-A400, a freighter with forward freight door. The follow-up YS11-A500, -600 and -700 were equivalent to the -200, -300 and -400, but with 1,100lbs / 500kg increased max takeoff weight. Production ceased in February 1974.
