3 years on: no final report and no answers to China Eastern plane disaster
Chinese authorities opt out of issuing update on MU5735 crash investigation

The cause of China’s worst plane crash in 30 years remains unknown, with Chinese authorities opting to not file a progress report on the third anniversary of the disaster.
The International Civil Aviation Organization (ICAO) convention requires the country conducting an air accident investigation to publish the final investigation report within 12 months of the event. If this is not done, the investigating authority must publish an annual update on the anniversary of the accident each year.
Instead of a final report on the Boeing 737-800 crash, the Civil Aviation Administration of China (CAAC) released updates in 2023 and 2024. But it did not do so on Friday for the third anniversary.
The incident was China’s worst air crash since 1994 and ended the country’s world-record run for aviation safety. Before the crash, Chinese carriers had amassed more than 100 million hours of safe flying.
A family member of one of the crash victims told the South China Morning Post on Thursday that they had not been told how the investigation was progressing, only learning about last year’s briefing from the news.
