The European Union Aviation Safety Agency (EASA)'s certification process for China's large aircraft, the C919, has garnered significant attention. Media reports indicate that EASA Director-General Florian Guillermet has officially communicated to Commercial Aircraft Corporation of China (COMAC) that the C919 will not achieve certification by 2025, with the entire certification process anticipated to extend between 3 to 6 years. EASA's collaboration with COMAC, which commenced approximately four years ago, involves rigorous verification of aircraft design, components, and test flights. As China's first jetliner independently developed in accordance with international airworthiness standards, the C919's international certification process holds immense significance for the nation's aviation industry.
