The third batch-produced AG600 Kunlong (1103) - China's domestically developed large civil amphibious aircraft - has rolled off the final assembly line and successfully completed its production test flight, marking an important transition for the AG600 program from type certification to small-batch production, according to the aircraft developer, Aviation Industry Corp of China (AVIC), Science and Technology Daily reported.

The second batch-produced AG600 Kunlong amphibious aircraft (1102) completed its production test flight in August. The forward fuselage section of the fourth batch-produced aircraft (1105) has been delivered to AVIC General Huanan Aircraft Industry Co, according to Science and Technology Daily.

The AG600 Kunlong aircraft is specially designed to meet urgent needs for forest firefighting and maritime rescue. It is also the world's largest civil amphibious aircraft by maximum takeoff weight, the report said.

The Chinese Society of Aeronautics and Astronautics and the China Aero-Space Tooling Association recently released standards for water scooping sites for AG600 series aircraft. Led and organized by AVIC General Huanan Aircraft Industry Co, the standards are China's first technical specification specifically for water scooping sites for large amphibious aircraft, CCTV News reported.

These standards fill a gap in both domestic and international regulations and mark a key step forward in establishing a supporting standards system for China's domestically produced large-scale emergency rescue equipment. It specifies multiple key technical parameters for water scooping sites and sets detailed operational limits on conditions such as wind speed, wave height, and visibility to ensure flight safety, CCTV News reported. 

The standards will take effect on November 1 and has already been preliminarily applied in water scooping site surveys in Northeast China's Jilin Province and East China's Zhejiang Province, the report said.
