COMAC C919 the new Chinese airliner.

The COMAC C919 is part of China’s bid to be a major player in the big airliner manufacturing market.  The Chinese state-owned manufacturer, Commercial Aircraft Corporation of China (COMAC), was established in Shanghai on 11 May 2008 with this mission in mind. The manufacture of large airliners is perhaps one of the most technologically challenging industries that exist in the world today.  The fact that Boeing and Airbus have managed stay in this space for so long is testimony to their expertise and their ability to withstand the school of hard knocks.

The C919 airliner is the largest commercial airliner to be designed and built in China. The design is a twin-engined jet airliner that will be put up in competition with the Airbus A320 and the Boeing 737.  This is a very lucrative market that Boeing and Airbus fight over vigorously, as these aircraft are the mainstay of Low-Cost Carrier fleets.

Filling the 158 – 174 seat market, the Comac C919 is the first phase of China’s plan to be a supplier to one-third of the world’s large airliner needs. Like Boeing and Airbus, COMAC intends to have solutions for every segment of the jet transport market. There are already plans in place for the larger C929, offering 300 seats and the C939 offering 400 seats.

COMAC C919 Airplane

The C919 is designed and built in China and is of a similar layout to the Boeing 737 and Airbus A320, being a twin-engined, low-winged, single-aisle aircraft. To look at, the C919 resembles the A320 a bit more than the 737.  The nose section is sleek looking much like the Boeing 787 Dreamliner, whereas the tail section of the fuselage is more Airbus-like, with the endpoint being aligned with the cabin roof rather than the Boeing style of having a cone with the endpoint being halfway between the top and bottom of the fuselage.

COMAC C919 Design

Shanghai is the central point for the design and production of the C919. Like Airbus and Boeing, the various components that make up the C919 are manufactured by other entities. These are spread over China, for example, the flaps, ailerons, wing panels, centre and outer wing box will be manufactured in Xi’an, China. The fuselage sections will be made in Jiangxi Province. These parts will all be brought together in Shanghai to complete the end product C919.  Most of the air-frame of the C919 makes use of aluminium alloys, with the centre wing box making use of carbon fibre composite materials.

The assembly of the COMAC C919 takes place in Shanghai.

COMAC C919 Foreign Components

Whilst the C919 is said to be Chinas’ own homegrown airliner, there are still many parts that are being supplied by foreign manufacturers. This of course is not unusual as both Boeing and Airbus adopt the same strategy in the production of their own airliners. Whilst the list of suppliers currently might feature many non-Chinese entities, rest assured this is only until such time as China can ramp up their own technology to built these parts themselves. For example, the engines which are currently supplied by the General Electric joint venture with AVIC will be replaced by the Chinese developed CJ1000. The government has a development beginning 2021-2025. This could take 15 years. The list below shows some of the main suppliers of components for the C919.

COMAC C919 History

Building a new airliner for the first time is a very challenging and time-consuming affair.  Even seasoned plane makers such as Boeing and Airbus have suffered many delays in bringing their new prototypes to fruition.  New technologies, new ways of manufacturing and doing things for the first time are all factors that will make the journey a long one.

Comac C919 – Commercial Aircraft Corporation Of China.

With the development of the C919, COMAC initiated an agreement of cooperation with Irish Low-Cost Carrier, Ryanair.  This agreement lasted six months and enabled airline perspectives to be taken into consideration during the design phase.  From here COMAC went ahead and created the design for the C919.

C919 Timeline

Date  Event
 11 May 2008 COMAC (Commercial Aircraft Corporation of China, Ltd.) is established with the aim of building airliners to reduce the dependency on foreign airliner makers.
 28 October 2010 COMAC applies to the Civil Aviation Authority of China for type certification of the C919.
 November 2010 At the Zhuhai Airshow COMAC announced it had received 55 orders for the C919 from: Air China, CDB Leasing Company, China Eastern Airlines, China Southern Airlines, GE Capital Aviation Services and Hainan Airlines.
 June 2011 COMAC and Ryanair sign a cooperation agreement on the development of the C919
 20 October 2011 ICBC Leasing agree to be the C919 launch customer with an order of 45 aircraft.
 11 November 2014 At the Zhuhai Airshow China Merchants Bank(Leasing) orders 30 C919s.
 24 November 2011 The COMAC / Ryanair agreement is concluded.
 9 December 2011 Construction of the first C919 prototype begins. Assembly was expected in 2014 with a first test flight in 2015.

 02 November 2015 The first completed C919 rolls out.
 April 2017 High speed taxi tests completed.
05 May 2017 The maiden flight of the Comac C919. 4,200 hours of testing required to meet a projected launch in 2020 but will more than likely slip to 2021.
 28 September 2017 The second flight of the COMAC C919, 2 hours 46 minutes to a height of 10,000ft. The delay of five months between first and second flights is quite unusual.
 28 July 2017 The second COMAC C919 prototype is completed. The flight test program called for six aircraft.
 03 November 2017 The third flight lasting 3 hours 45 minutes to a height of 9,800ft.

 27 November 2020 The CAAC issued a type inspection authorisation. This basically means that aircraft design is finalised and no major structural changes can now be made.

C919 Specs

The first iteration of the family of airliners planned by COMAC is the 156-174 seat C919.  This will be the smallest of the plane makers’ offerings and looks to be offered in 6 variations. It is hard to know if this encompasses the whole fleet of C919, C929 and C939.  The offerings are called: Baseline, Stretched, Freighter, Shortened, Business and Specials.

The C919 flight deck features a side control stick in place of the centre control column preferred by Boeing. As well as the large display screens, note the HUD glass panels at the top of the picture.

The C919 flight deck is very much along the lines of the Airbus style, with a side control joystick instead of the standard control column controlling the fly by wire system. Instrumentation is state of the art with two 15.4 inch main display screens in front of each pilot as well as a 12.5 inch side screen below the window. In addition, the C919 will be offered with the option of a HUD (Head Up Display). This is used in fighter jets where instrument data is projected onto a window in front of the pilot so he can monitor data such as airspeed, altitude and other information without having to look down. In other words his/her head remains up.
