First on CBS: Chinese authorities may already be examining a black box recorder from downed flight that left 132 dead
U.S. officials are concerned their Chinese counterparts may be proceeding with extracting data from China Eastern Airlines flight 5735's flight data recorder without National Transportation Safety Board officials present, CBS News has learned.
The Civil Aviation Administration of China — its version of the Federal Aviation Administration and NTSB — announced one of the recovered black boxes which is believed to hold audio recordings from the flight deck was already en route to Beijing for analysis overnight.
Almost five days since the crash, in which no survivors were found, the NTSB go-team is still stateside working with the State Department to streamline travel to and from China without having to adhere to the strict COVID-related quarantine requirements.
The NTSB has already appointed a senior air safety investigator, Dr. Sathya Silva, to lead the go-team which includes technical advisers from Boeing, which built the 737-800 model aircraft, CFM, which supplied the engines, and the FAA.
The UN's agreement on aviation standards establishes that the state where an aircraft was designed and manufactured is entitled to appoint a senior investigator who is authorized to assign technical advisers. Therefore, U.S. experts are supposed to be assisting Chinese officials in-country every step of the way.
While virtual communications are a possibility, it is not preferred as it also creates potential issues with secure communications and erases any chance of essential in-person analysis, a source with knowledge of the process tells CBS News.
Chinese officials also announced human remains were found at the crash site as the search continues for the doomed aircraft's second data recorder, which records crucial flight information. The cause of the flight's almost vertical dive from 29,000 feet remains a mystery. One-hundred-thirty-two people on board perished in China's worst aviation disaster in more than a decade.
