The Comac C919 is a planned family of 158–174 seat narrow-body twin-engine jet airliners to be built by the Commercial Aircraft Corporation of China (Comac).〔 It will be the largest commercial airliner designed and built in China since the defunct Shanghai Y-10. Its first flight is expected to take place in 2016, with first deliveries scheduled for late 2018. The first model off the production line was rolled out in Shanghai on November 2, 2015. The C919 forms part of China's long-term goal to break Airbus and Boeing's duopoly, and is intended to compete against Airbus A320, Boeing 737 and Irkut MC-21. As a long term plan the twin‑engine, twin aisle C929 and C939 are proposed, offering 300 and 400 seats, respectively. ==Development== Comac applied for a type certificate for the aircraft from the Civil Aviation Authority of China on 28 October 2010. The company plans to conduct the first flight of the C919 in 2016, with deliveries beginning in 2018,〔 whereas Marwan Lahoud, Chief Strategy & Marketing Officer of Airbus Group,〔(【引用サイトリンク】title=Airbus Group – media )〕 assumes a competition outside China around 2020.〔(Airbus to Seek Alliances as Rivals Try to Sell Big Planes ) Bloomberg〕 In June 2011 COMAC and Irish low-cost airline Ryanair signed an agreement to co-operate on the development of the C919〔(【引用サイトリンク】title=Welcome to Ryanair! )〕 On 24 November 2011, Comac announced the completion of the joint definition phase, marking the end of the preliminary design phase for the C919.〔 The company said it planned to cut the first metal for the aircraft in December 2011, with estimated completion of the detailed design phase in 2012. With an estimated development cost of $8.3 billion, Comac planned to produce 5–10 planes per year in 2016 and 2017, subsequently ramping up to 150 C919s. The company intends to manufacture up to 2,300 aircraft of that type.〔Aboulafia, R. Comac C919 Program Briefing. World Military & Civil Aircraft Briefing. 2010.〕 In 2014 delivery was yet again delayed by technology and supplier problems, this time to 2018. Comac rolled out its first C919 aircraft off the assembly line in September 2015 with no engines installed. On November 2, 2015, Comac rolled out its first C919 aircraft. 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「Comac C919」の詳細全文を読む スポンサード リンク
