A Swiss International Airlines Bombardier C-Series CS-300, registration HB-JCD performing flight LX-1885 from Bucharest Otopeni (Romania) to Zurich (Switzerland) with 74 passengers and 5 crew, was enroute at FL400 about 20nm eastnortheast of Graz (Austria) when the crew decided to divert to Graz reporting smoke on board. The aircraft landed on Graz's runway 34 and stopped on the runway about 19 minutes after the decision to divert. The aircraft was evacuated. A rescue helicopter positioned to the aircraft on the runway, took a flight attendant under resuscitation on board and flew him to a hospital, the flight attendant died on Dec 30th 2024. About 17 passengers and a number of crew needed medical attention, too.

The airline stated: "The cockpit crew decided to make an unscheduled landing in Graz. The aircraft is currently on the runway, the passengers have been evacuated. More information will follow." The airline subsequently added that following engine (PW1524G) trouble and smoke in cockpit and cabin they are concerned about one of their cabin crew, the other four crew also went to see doctors. Later the airline announced two additional flights were scheduled to fly to Graz, one with a care team for the passengers and crew already during the night, and another one to take the passengers to their destination the following morning. The cause of the smoke is currently under investigation. 17 passengers required medical attention.

Local Police reported one member of the crew received serious injuries and is currently in the Intensive Care Unit of a local hospital, 13 passengers received minor injuries. Both pilots and 2 cabin crew were taken to the hospital, too.

A replacement BCS3 registration HB-JCG reached Zurich the following morning with a delay of about 12.5 hours.

On Dec 26th 2024 the airline reported that two of three cabin crew are still in hospital care, one of them still in the intensive care unit. The investigation is working diligently to clarify the causes of this accident, in the focus are mechanical components like engines but also the use of the Protective Breathing Equipment (PBE).

On Dec 30th 2024 the airline reported that the seriously injured flight attendant died.

On Jan 5th 2025 the Austrian States Attorney reported that an autopsy revealed the flight attendant had died because of serious brain damage (oedema and hypoxic brain damage) caused by lack of oxygen supply. The flight attendant had an extremely enlarged heart and there are indications he suffered from septic bronchitis. Whether this is connected to the cause of death is part of further investigation, the role of the protective breathing equipment is also subject of investigation.

On Jan 5th 2025 The Swiss Federal Prosecution Office said they are investigating as well and are in contact with the Austrian Prosecution Office in Graz. The crew member had worn a protective breathing equipment (PBE), which according to findings by the airline in 2023 was error-prone, the airline began exchanging the PBEs however had not yet completed the exchange.

On Jan 10th 2025 The Aviation Herald received information stating that the later investigation leader of the Austrian SUB put the PBEs into a bag and handed it to an airport employee to take it out of the airport to the car of the investigation leader, where the PBEs were left unattended for some time until the later investigation leader - an investigation had not yet been opened on December 23rd, only on December 30th when it became known the flight attendant had died - drove away with the PBEs. The later investigation leader subsequently was not reachable until December 30th. A first examination of the PBEs by police in Graz found differences to the video material taken by passengers. Confirmation of this information was obtained by The Aviation Herald only on Jan 22nd 2025 when the airport of Graz confirmed, that an employee was asked by staff of the SUB to take packaged materials to the vehicle of the investigator. It thus is unclear whether the investigation leader took the PBEs legally or not. Austria's Ministry for Mobility, Innovation and Technology stated, an investigation was opened on Dec 23rd 2024. However, investigation authorities in the countries of manufacturers (aircraft, engine, ...) as well as the airline were informed about the opening of the investigation only a week later.

According to information The Aviation Herald received the left hand engine suffered an oil leak causing the smoke, the engine seized as result of an uncontained failure. The engine's main shaft was found fractured. The engine is being replaced.
