Recently, COMAC delivered the world's first C919 large passenger aircraft to China Eastern Airlines, with the registration number of B-919A. At the delivery ceremony, CAAC issued B-919A's nationality registration certificate, standard airworthiness certificate (AC) and radio license. Prior to this, C919 has obtained Model Certificate of Conformity (TC) and Production License (PC). In addition, today, it has been issued with a standard airworthiness certificate (AC) for each single aircraft, which indicates that C919 will be used in the domestic market as a qualified civil aircraft. C919 passenger aircraft, together with Airbus A320 series passenger aircraft and Boeing 737 series passenger aircraft, which are common in daily civil aviation travel, are medium range narrow body trunk airliners, and are the type of passenger aircraft with the largest demand and use in the world civil aviation market today. According to the prediction of many aircraft manufacturers, including Airbus, Boeing, COMAC and the aviation industry, the demand for new narrow trunk airliners in China's civil aviation market in the next 20 years will be 5000-7000, while the demand for new narrow trunk airliners in the global market will exceed 30000. Such a huge demand for new aircraft means that no aircraft manufacturer has the ability to occupy the market alone. The future civil aviation passenger aircraft market is still a blue ocean for new companies and aircraft. It can be said that C919 was born at the right time. As a domestic large passenger aircraft developed in accordance with internationally accepted airworthiness standards and with independent intellectual property rights, the C919 is a large civil aircraft fully oriented to market demand, and also a product of global cooperation. Many core components are not only supplied by foreign parts manufacturing contractors such as GE and CFM International, but also developed by domestic suppliers such as AVIC Shenfei and AVIC Xifei. A common feature of these international and domestic parts manufacturing contractors is to provide manufacturing services for all civil airliners in the world. In a sense, C919 has the strength to compete with A320 and 737. The aviation manufacturing industry is a knowledge and technology intensive industry with a long industrial chain and many related industries. Global cooperation is a trend, and it is also the best choice to improve efficiency and reduce costs. No country or community of countries can independently develop aviation manufacturing. In today's world, the development of advanced industries such as aviation manufacturing cannot go against the tide of globalization, which will only lead to complacency. It is the global cooperation that has brought the C919 more excellent performance, enabling it to enter the civil aviation passenger transport market faster with a more international standard. From the perspective of global cooperation, we can still be proud of C919. The success of the development and production of domestic large aircraft marks a breakthrough in China's aviation manufacturing capacity. The technical level of the aviation manufacturing industry cluster has been further improved in international cooperation. The country's comprehensive strength has been further advanced, and the level of advanced manufacturing industry will take off again. After COMAC delivered the first C919, Boeing and Airbus, the two largest aircraft manufacturers in the world, congratulated one after another, saying that China had brought a new model to the global civil aviation market, and looked forward to the industry peers' continuing commitment to the long-term sustainable development of the aviation industry. This is a recognition, but also an invitation to compete on the same stage. The delivery of the first C919 is the new product of China's aviation manufacturing industry
