Boeing suspended the delivery of airliners to China because the review of the battery in the Boeing 25-hour cabin sound recorder (CVR) module has not been certified by the Civil Aviation Administration of China. Boeing told reporters that it is cooperating with China Airlines customers to determine the timing of aircraft delivery once the Civil Aviation Administration of China has completed the review of the battery in the 25-hour CVR module. Boeing also said that the system has previously been certified by the US Federal Aviation Administration (FAA) and the European Union Aviation Safety Administration (EASA). However, Boeing did not disclose which models the review will affect delivery and where the review will proceed. (Caixin)
