In April 2020, Shandong Xiangyu obtained the approval for the modification of the lap belt of 737 aircraft. For the first time, the CTSO lap belt designed and manufactured by Shandong Xiangyu was used to replace the imported lap belt, which reduced the maintenance cost of the customer while ensuring safety. On October 16, 2018, the first batch of 254 sets of EFB charging components manufactured by Shandong Xiangyu were successfully delivered to customers. The successful approved acquisition and delivery of these batches of EFB charging components meant that Shandong Xiangyu made a huge breakthrough in the electronic modification project. Shandong Xiangyu will continue to increase efforts to focus on customers and provide them with customized technical services and modification solutions.
