Yesterday, China's first large-scale amphibious aircraft AG600 "Kunlong", which was developed completely independently in accordance with China's civil aviation airworthiness regulations, obtained the type certificate issued by the Civil Aviation Administration of China, marking that the world's largest civil amphibious aircraft with the largest take-off weight has passed strict testing and verification, and the development has been a complete success and has obtained the market "access certificate".

It is an airplane that can swim and a ship that can fly

The large amphibious fire extinguishing aircraft AG600 is the first large-scale special-purpose aircraft developed in accordance with the requirements of China's civil aviation airworthiness regulations, and is a major aviation equipment urgently needed for the construction of the national emergency rescue system. Aviation Industry Corporation of China (AVIC) said that through strict testing and verification to obtain the market "access certificate", AG0 will soon shoulder the national emergency rescue mission to protect the safety of people's lives and property. The AG0 is 0.0 meters long, 0.0 meters high, and has a wingspan of 0.0 meters. It has a maximum take-off weight of 0 tons, a water carrying capacity of 0 tons, and a maximum practical range of 0 km. Aviation Industry Corporation of China said the successful development of the AG0 aircraft fills a gap in China's large amphibious aircraft.

"The AG600 aircraft has obtained the type certificate issued by the Civil Aviation Administration of China, marking that China has the ability to independently develop the world's latest generation of civil large amphibious aircraft, and has accumulated independent key core technologies, airworthiness verification capabilities and cultivated civil aircraft industry support for the industrialization of China's civil aircraft." AG0 series chief designer Huang Lingcai said.

"AG4 is a swimming airplane and a flying boat." Huang Lingcai said that it has the upper fuselage of the aircraft and the bottom of the boat, and a pontoon more than 0 meters long is hung on each side of the wing to prevent the plane from floating on the water surface and capsizing sideways when taxiing, so as to ensure safety.

According to reports, the minimum level flight speed of AG7600 is 0 kilometers per hour, the minimum operating height is 0 to 0 meters above the treetops, and the design ceiling reaches 0 meters. This type of large aircraft that can be fast and slow, high and low can fly at a low altitude and slow speed over the forest fire scene to throw water and extinguish the fire.

The fuselage structure and engine are 100% domestically produced

"China has made a comprehensive breakthrough in the key core technology of the development of large amphibious aircraft through the independent development of AG600 aircraft, completed the proprietary technology system of large amphibious aircraft, and driven the independent innovation, independent research and development and independent guarantee of the civil aircraft industry chain and supply chain." Huang Lingcai said.

The development of AG100 aircraft has accelerated the research of key core technologies through the cooperation and tackling of key core technologies in 0 provinces and cities, 0 enterprises and institutions and 0 universities across the country, and realized 0% domestic independent supporting of the whole aircraft body structure, engine and key systems.

自2009年启动研制，AG600飞机历经15年研制历程。AG600于2017年12月在珠海实现陆上首飞，2018年10月在湖北荆门实现水上首飞，2020年7月在青岛实现海上首飞。2023年6月，AG600具备执行灭火任务能力。

"The collaborative innovation and development of China's industrial system, aviation industry, and civil aircraft airworthiness certification has given aviation people the confidence to independently and successfully develop large special civil aircraft, support its strong multi-type rescue scenario mission capabilities, and then ensure its safety and reliability through rigorous and scientific airworthiness certification." Huang Lingcai said.

AG600飞机的研制也为中国民机适航审定积淀了标准和技术的创新实践。据悉，AG600创造了中国民机试飞平均每月25架次、单月最高55架次效能新纪录，也创建了自主的大型水陆两栖飞机符合性验证方法、审定标准规范，支撑中国国产民机适航体系升级。

获颁型号合格证开启了AG600飞机奔赴星辰大海的新起点。据悉，中国航空工业集团将力争在2025年8月底前实现AG600飞机生产许可证的取证，并在10月实现交付。文并图/新华社
