Why did China Airlines stop flying?

China Airlines was temporarily suspended due to "security risks". On August 28th, the wing tip of China Airlines flight G52744 from Shijiazhuang to Guiyang rubbed against the ground during the landing, which was the fuse that led to the suspension of China Airlines. After the incident, the Southwest Regional Administration of Civil Aviation thought it was a serious unsafe incident. At the same time, the notice pointed out that the continuous safety supervision carried out by the Administration and Supervision Bureau this year showed that the company's management of existing safety hazards was not timely and thorough, the company's operation lacked effective control, and the safety management was not perfect. Therefore, the Southwest Regional Administration of Civil Aviation requires China Airlines to immediately carry out safety rectification and accept the investigation of the incident by the investigation team of the Administration, and the Administration will further deal with the company according to the incident investigation and safety inspection. "When to resume operation will be decided by the Administration according to the inspection results." According to the reporter's understanding, Huaxia Airlines is the only truly independent regional airline in China. This company has only been in operation for four years. At present, two operation bases in Guiyang and Chongqing and Ganzhou branch have been established, and more than 20 routes have been opened, reaching nearly 30 cities. Huaxia Airlines is a Sino-foreign joint venture airline, which was established with a joint investment of RMB 80 million by domestic private enterprises Shanghai Shang Hong Industrial Holding Group Co., Ltd., Beijing Longkai Chuangxing Technology Development Co., Ltd., two foreign-funded enterprises Elite International Co., Ltd. and Dempuni International Co., Ltd.. It is the first private airline specializing in regional passenger and cargo transportation in China.
