Singapore Airlines Flight Faces Severe Turbulence, Rapid G Force Changes

A Singapore Airlines flight from London to Singapore experienced severe turbulence, resulting in rapid changes in G-forces that led to one fatality and multiple injuries. The incident occurred on May 21, 2024, when the Boeing 777-300ER was flying over Myanmar.

The Singaporean Ministry of Transport (MOT) published its initial findings, revealing that the aircraft's flight data recorder (FDR) and cockpit voice recorder (CVR) data indicated an uncommanded increase in altitude due to an updraft. The aircraft climbed from 37,000 feet to 37,362 feet before descending back, causing rapid fluctuations in G-forces. This turbulence caused vertical accelerations to change drastically, lifting unsecured passengers into the air.

The flight crew turned on the seatbelt sign just eight seconds before the turbulence hit, but the sudden changes in G-forces were severe. The aircraft's autopilot was disengaged during the turbulence, and the pilots manually flew the plane for 21 seconds before re-engaging the autopilot. The turbulence caused the plane to drop by 178 feet, contributing to injuries among passengers and crew.

Following the incident, the flight diverted to Bangkok Suvarnabhumi Airport (BKK), where it landed safely at 08:45 UTC. Eighteen passengers were hospitalized, and twelve others received treatment for injuries. Unfortunately, there was one fatality.

Singapore Airlines has since reviewed and updated its seatbelt policies. The airline now suspends hot drink and meal services when the seatbelt sign is on, secures loose items in the galley during turbulent weather, and ensures passengers return to their seats when the seatbelt sign is activated. These measures aim to enhance passenger and crew safety during turbulence.

The investigation into the incident is ongoing, and Singapore Airlines has committed to supporting the affected passengers and their families, including covering medical expenses and providing additional assistance as needed.
