Singapore Airlines turbulence incident: Investigation continues one year later

More than a year after the turbulence incident involving a Singapore Airlines Boeing 777-300ER, the Singaporean authorities have provided an update on their ongoing investigation. The flight from London to Singapore encountered severe turbulence, resulting in one fatality due to a heart attack.

The Transport Safety Investigation Bureau (TSIB) of Singapore announced that components of the aircraft's weather radar system have been sent to the United States for examination and testing. "Components of the aircraft’s weather radar system have been sent for examination and tests in the US. The component examination and test report detailing the findings is still pending. The TSIB will make public its Final Report upon completion of the investigation," stated TSIB.

The preliminary findings were published on May 29th, 2024, revealing that data had been extracted from both the cockpit voice recorder and flight data recorder. According to these findings, as Flight SQ321 flew over southern Myanmar on May 21st, 2024, it likely cruised above an area with developing convective activity. This led to slight vibrations with vertical accelerations fluctuating between positive 0.44G and 1.57G for about 19 seconds.
