COMAC C919

The COMAC C919 is part of China’s bid to become a major player in the large airliner manufacturing market. The state‑owned 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 one of the most technologically challenging industries in the world. The fact that Boeing and Airbus have dominated this space for decades is testimony to their expertise and their ability to withstand the school of hard knocks.

The C919 is the largest commercial airliner ever designed and built in China. It is a twin‑engined narrow‑body jet positioned to compete directly with the Airbus A320 and Boeing 737. This is a lucrative market segment that Boeing and Airbus fight over vigorously, as these aircraft form the backbone of low‑cost carrier fleets worldwide.

Filling the 158–174 seat market, the C919 is the first phase of China’s plan to supply one‑third of the world’s large airliner needs. COMAC intends to offer solutions for every segment of the jet transport market. Plans are already in place for the larger C929 (300 seats) and C939 (400 seats).

Shanghai is the central point for the design and production of the C919. As with Airbus and Boeing, many components are manufactured by other entities across China. For example, flaps, ailerons, wing panels, and wing box structures are produced in Xi’an, while fuselage sections are built in Jiangxi Province.

These parts are transported to Shanghai for final assembly. Most of the C919 airframe uses aluminium alloys, while the centre wing box incorporates carbon‑fibre composite materials.

Development Timeline

The development of the COMAC C919 represents China’s most ambitious commercial aviation project to date. The program was created to establish a domestic alternative to the Airbus A320 and Boeing 737 families, reduce reliance on foreign aircraft, and build a foundation for future wide‑body programs such as the C929 and C939.

The timeline below outlines the major phases of the C919’s development, from program launch to certification and early production.

Program Origins

China’s desire to build a large commercial airliner dates back to the 1970s, but the modern push began in the early 2000s. In 2008, the Chinese government formally established COMAC in Shanghai to lead the nation’s commercial aircraft ambitions. The C919 was announced as the first major project, intended to compete directly in the lucrative single‑aisle market.

Concept & Design Phase (2008–2011)

COMAC began the conceptual design of the C919 shortly after its formation. The aircraft was planned as a modern narrow‑body jet with fly‑by‑wire controls, advanced avionics, and a global supply chain similar to Airbus and Boeing.

During this phase, COMAC signed a six‑month cooperation agreement with Ryanair. The partnership allowed COMAC to incorporate operational feedback from a major low‑cost carrier, influencing cabin layout, turnaround efficiency, and maintenance considerations.

By late 2010, COMAC submitted its application for type certification to the Civil Aviation Authority of China (CAAC), marking the transition from concept to formal development.

Supplier Selection & Industrial Partnerships (2010–2013)

COMAC adopted a global sourcing strategy, selecting experienced international suppliers for critical systems. This included CFM International for engines, Honeywell and Rockwell Collins for avionics, Liebherr for landing gear and air‑conditioning systems, and multiple AVIC subsidiaries for structural and systems integration.

While the aircraft was promoted as “homegrown,” COMAC’s strategy mirrored Airbus and Boeing: combine domestic manufacturing with proven international technology to accelerate development.

During this period, COMAC also began early work on the future Chinese‑developed CJ‑1000A engine, intended to eventually replace the LEAP‑1C.

Prototype Construction (2011–2015)

Construction of the first C919 prototype began in December 2011. COMAC established a distributed manufacturing network across China, with major components produced in Xi’an, Chengdu, Shenyang, and Jiangxi, then transported to Shanghai for final assembly.

By September 2015, the first prototype rolled off the assembly line without engines. The fully assembled aircraft was unveiled on 2 November 2015, marking a major milestone for the program.

Flight Test Program (2017–2022)

The maiden flight took place on 5 May 2017. COMAC planned a six‑aircraft test fleet to complete approximately 4,200 hours of flight testing. The program included performance validation, avionics integration, structural testing, and cold‑weather and high‑altitude trials.

Flight testing was conducted at multiple locations across China, including Shanghai, Xi’an, Dongying, and Nanchang. The test program progressed steadily, though with several delays typical of first‑time aircraft development.

By late 2020, the CAAC issued type inspection authorisation, confirming the aircraft’s design was frozen and ready for final certification testing.

Certification & Entry Into Service (2022–2023)

The C919 received CAAC type certification on 29 September 2022. China Eastern Airlines, the launch customer, took delivery of the first aircraft on 9 December 2022.

The C919 entered commercial service on 28 May 2023, operating flight MU9191 from Shanghai Hongqiao to Beijing Capital Airport. This marked the beginning of China’s first domestically produced large commercial jet entering regular airline operations.

Future Development: C929 & C939

The C919 is the foundation of COMAC’s long‑term strategy. The next step is the C929, a wide‑body twin‑aisle aircraft developed jointly under the CRAIC partnership. The C939, a larger 400‑seat concept, remains a long‑term vision.

These aircraft are intended to compete with the Airbus A330neo, A350, Boeing 787, and 777 families, positioning China as a full‑range commercial aircraft manufacturer.

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 new prototypes to fruition. New technologies, new manufacturing methods, and doing things for the first time all contribute to a long development journey.

During the development of the C919, COMAC initiated a cooperation agreement with Irish low‑cost carrier Ryanair. This agreement lasted six months and allowed airline operational perspectives to be incorporated into the design phase. From here, COMAC proceeded with the final design of the C919.

The assembly of the COMAC C919 takes place in Shanghai.

Whilst the C919 is said to be China’s own homegrown airliner, many components are still supplied by foreign manufacturers. This 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 features many non‑Chinese entities, this is only until such time as China can ramp up its own technology to build these parts domestically. For example, the engines currently supplied by the General Electric joint venture with AVIC will eventually be replaced by the Chinese‑developed CJ1000. The government has a development project beginning 2021–2025, and this could take up to 15 years.

The list below shows some of the main suppliers of components for the C919.

Legacy

The COMAC C919 represents a major milestone in China’s aviation history. It is the first domestically produced large commercial jet to enter airline service, marking China’s arrival as a serious participant in the global aerospace industry. While the aircraft currently relies heavily on international suppliers, its development has laid the foundation for future Chinese‑built systems, including engines, avionics, and advanced composites.

The C919’s entry into service breaks the long‑standing duopoly held by Airbus and Boeing in the narrow‑body market. Although the aircraft is not yet certified outside China, its domestic order book of more than 1,000 aircraft provides a strong industrial base and ensures long‑term production stability. As manufacturing capacity increases, the C919 will become a familiar sight across China’s rapidly expanding aviation network.

Beyond the aircraft itself, the C919 program has accelerated China’s aerospace capabilities. It has driven investment in research, manufacturing, supply chain development, and workforce training. These advancements directly support the next stages of COMAC’s strategy: the C929 wide‑body and the larger C939 concept. Together, these aircraft aim to position China as a full‑range commercial aircraft manufacturer capable of competing in both single‑aisle and twin‑aisle markets.

The C919’s legacy will ultimately be measured not only by its operational success, but by the long‑term transformation it brings to China’s aviation industry. It is a stepping stone toward greater technological independence, expanded global influence, and a future where Chinese‑built airliners operate alongside the world’s most established aircraft families.
