Switzerland’s Transportation Safety Investigation Board (Sust) has officially taken over the investigation into the emergency landing of a SWISS Airbus A220 in Graz, Austria, on December 23, 2024. The flight, en route from Bucharest to Zurich, was forced to land due to engine trouble and smoke in the cabin. Several passengers and crew were injured, and a 23-year-old flight attendant later died.
Though the incident occurred in Austria, which would normally lead the probe, the Austrian Safety Investigation Board (SUB) stepped aside following a criminal complaint and internal investigation into possible misconduct. To avoid allegations of bias, Austria dismissed the original investigator, and Switzerland has assumed full responsibility for the inquiry.
