A YS-11 of Japan Air Commuter
Role Turboprop Airliner
Manufacturer Nihon Aircraft Manufacturing Corporation
First flight August 30, 1962
Introduced March 30, 1965 for All Nippon Airways
Produced 1962-1974
Number built 182

The NAMC YS-11 is a turboprop airliner built by a Japanese consortium, the Nihon Aircraft Manufacturing Corporation. The program was initiated by the Ministry of International Trade and Industry in 1954: the aircraft was rolled out in 1962, and production ceased in 1974.

To date, the YS-11 is the only successful commercial aircraft made by a Japanese firm, either before or after World War II. 182 were produced in total. Although most of the aircraft was designed and manufactured in Japan, the engines were built by Rolls-Royce. Also, electrical appliances, gauges, machinery and cockpit hardware were supplied either from Japanese Industries or foreign overseas providers during the YS-11's time of production.

The consortium of companies that made up NAMC included Mitsubishi Heavy Industries and Fuji Heavy Industries (now better known as the parent company of automobile manufacturer Subaru), both major producers of fighter planes during World War II. The twin-engined YS-11 delivered similar operational performance to the four-engined Vickers Viscount, and had 50% more capacity than the similarly-configured Fokker F.27.

On September 30, 2006, Japan Air Commuter flight 3806 marked the final flight for a YS-11 in Japan's commercial aviation industry. In 2007, the YS-11 was added to the Mechanical Engineering Heritage of Japan No. 13.
