Investigation reveals 'unknown fault pattern' in engine following fatal emergency landing in Graz, marking most serious incident in airline's 23-year history.

"This is a dark day"
"The engine had suddenly and unexpectedly failed"
In a tragic turn of events, a SWISS Airlines crew member has died following an emergency landing in Graz, Austria. The incident occurred on December 23, 2024, when flight LX1885, operating from Bucharest to Zurich, was forced to make an emergency landing due to smoke in the cockpit and cabin. The Airbus A220 aircraft, carrying 74 passengers and five crew members, successfully executed the emergency landing, but the incident resulted in multiple injuries and, ultimately, one fatality.
Initial investigations have revealed a 'previously unknown fault pattern' in one of the aircraft's engines, according to an internal SWISS memo. The affected engine reportedly 'suddenly and unexpectedly failed' during the flight. The engine will be dismantled in Graz and transported to the United States for detailed examination by manufacturer Pratt & Whitney, in cooperation with relevant authorities. The Graz public prosecutor's office has launched an investigation focusing on negligent bodily harm, aiming to determine the precise cause of the smoke that necessitated the emergency landing.
The emergency evacuation required passengers to exit the aircraft via evacuation slides. Of the 79 people on board, twelve passengers and all crew members required medical attention. Two crew members were initially hospitalized, with one tragically succumbing to their injuries at the University Hospital Graz. The second crew member has since been discharged. Out of respect for the deceased's family, SWISS has not released detailed information about the victim or the specific cause of death.
SWISS Airlines' leadership, including CEO Jens Fehlinger and COO Oliver Buchhofer, described the event as a 'dark day' in a joint statement. The airline has been fully cooperating with investigating authorities and has notified both the aircraft and engine manufacturers. The Swiss Federal Office of Civil Aviation (FOCA) has been involved in the investigation process. SWISS, a subsidiary of Lufthansa, operates a fleet of 30 Airbus A220s, including 21 long-haul and 9 short-haul versions.
This incident marks the most serious event in SWISS Airlines' 23-year history. The Airbus A220 fleet has experienced previous engine-related issues, though none as severe as this incident. SWISS has maintained a strong safety record since its establishment in 2002, following the collapse of Swissair. The airline's commitment to safety has been a cornerstone of its operations, making this incident particularly significant in the context of Swiss aviation history.
