This past January, an individual from China filed a Freedom of Information Act request at NTSB, which replied to him yesterday, April 29th, 2026.

Documents provided by NTSB include a report on July 2022 downloaded data, emails exchanged between NTSB & CAAC (heavily redacted), and FDR data. Since the FDR lost power when engine fuel was shut off, it did not record any data for those final minutes.

CVR, however, had a backup battery and recorded everything. According to the report, all the CVR audio recordings were successfully downloaded in “excellent quality” and given to CAAC. "No CVR audio files or other raw or intermediate downloaded files" capable of being used to create audio files were kept by NTSB.
