NAMC YS-11. A photo. Video. Characteristics. Reviews.



NAMC YS11 is a Japanese turboprop airliner for medium and short haul lines. Manufactured and developed by the Nihon Aircraft Manufacturing Corporation by a consortium. The first flight of the analogue was made in 1962. Serial production was carried out in 1962-1974, 182 aircraft were produced.

Japan's Ministry of International Industry and Trade in the late 1950s wrote design requirements for an aircraft to replace the Douglas DC-3 on domestic airlines. The consortium for the production and design of this aircraft includes Kawasaki Heavy Industries, Mitsubishi Heavy Industries, Shin Meiwa, Fuji Heavy Industries, Japan Aircraft Industry Company and Showa Aircraft Industry Company; the consortium, formed in 1959, was named NAMC.

This multipurpose aircraft began to develop Japanese aircraft manufacturers in 1954 year and eight-year period of design has undergone many different changes, including how to design and technically. Initially it was assumed that the airplane will have exclusively the character of a passenger aircraft, but, in the course of drafting, it was decided to provide also the possibility of transport on this plane and all kinds of goods, which in the long run, and will make this a very popular aircraft.

This aircraft made its first flight in August 1962, however, not satisfying all the expectations of the leadership of the aircraft manufacturer, as well as representatives of the Ministry of International Trade and Industry, on whose initialization the development of this project began, the aircraft was sent for additional revision, where it was still in within three years, and only in 1965, the aircraft was able to perform its first commercial flight, which began the history of the operation of this aircraft.

The NAMC YS-11 aircraft is equipped with two Rolls-Royce Dart Mk.542-10K turboprop aircraft engines, each of which is capable of developing a thrust of 3030 hp, which provides the aircraft with a high carrying capacity, as well as a sufficiently high cruising speed, which, depending on from modification, about 454 km / h. The maximum flight range of the NAMC YS-11 cargo-passenger liner is also very acceptable, amounting to about 2200 kilometers, which made it possible to use it on medium-haul regional airlines.


Cabin NAMC YS-11


Depending on the modification, as well as the layout of the cabin, the aircraft NAMC YS-11 can accommodate up to 64 passengers, and if the plane was supposed to operate as a vehicle, the on board could accommodate up to 8900 kilogram payload that it is also quite satisfactory.

The aircraft NAMC YS-11 8 produced in basic versions:

  • NAMC YS-11 - the primary prototype of the aircraft used in the test flight in the 1962 year;
  • NAMC YS-11-100 - Basic production version of the airplane;
  • NAMC YS-11A-200 - modification with increased maximum take-off weight;
  • NAMC YS-11A-300 - Utility version of the aircraft, divided into the passenger compartment and cargo hold;
  • NAMC YS-11A-400 - A modified transport version of the aircraft;
  • NAMC YS-11A-500 - modification of the 1970 of the year, which is a passenger version with an increased maximum take-off weight;
  • NAMC YS-11A-600 - passenger-and-freight modification of the NAMC YS-11A-500 version;
  • NAMC YS-11E - special modification with improved power installation.


Today turboprop airliners are in limited use, however, continue to provide the performance of all tasks assigned to them, regardless of whether the carrying freight, or just transporting passengers.




The aircraft was operated extensively on domestic and imported lines of Japanese abroad. Bred in Japan to 2006 of operation.

It is noteworthy that a pair of YS-11A was exported. This YS11A was built in 1968 for the ALA of the Argentine aviation company. In it, it was used under registration number LV-JII until it was sold in 1981 to US-based Mid Pacific Air, which operated the aircraft until 1988 in Hawaii.

Greek "Olympic Airlines" was the only operator YS11 in Europe, although its aircraft soon went to the Greek Air Force.

Based on the YS-11A with extended takeoff weight models designed cargo, including YS11A200 "Combi", which is capable of carrying or cargo, or passengers. Cargo version is 400-Series, cargo - 600-Series with much greater take-off weight. All YS11A, -400, -300, -600, -500 planes were on the port side cargo door in the converted cargo planes and some others.

YS-11 used not only civilian airline - a large number of aircraft bought the Japan Self-Defense Forces.

JA8611 was the first of the NAMC YS11. He took off 30.08.1962. The initial version of the developer has not met expectations, primarily due to low power Rolls-Royce Dart engines.

The second analogue YS11, it is similar in appearance to the British Hawker Siddeley HS748. aircraft service in the regional aircraft Japanese company has received a long - last plane written off in the year 2006.

Sales in the US market were poor initially - only Hawaiian Airlines leased three aircraft. "

"Piedmont Airlines", American Airlines acquired 22 instance, but in the mid-80's they were replaced by DHC8.

The main customers of the YS11 in Japan are the aviation companies JDA, Toa and All Nippon. Toa Domestic Airlines, formed by the merger of JDA and Toa, was renamed Japan Air Systems and operated until the 2000s.

YS-11A-400 is a specially modified military transport aircraft. Under the code YS-11C, it was delivered to the Japanese Air Force Transport Aviation Wing. The Air Force squadron, which was stationed in Irum, received 3 copies of the YS11, which were then changed into electronic warfare training aircraft and received the name YS11E. Another six copies of the aircraft, named YS-11T, were in use by the Japanese Self-Defense Forces as training for training the crews of P-2J Neptune anti-submarine aircraft. Moreover, not all planes have been written off, at least 13 planes are still in operation. The Greek Air Force used one aircraft for calibration work.
