A Finnair Airbus A350-900, registration OH-LWH performing flight
AY-141 from Helsinki (Finland) to Bangkok (Thailand), was climbing out of Helsinki's runway 15 when the crew stopped the climb at 4000 feet due to smoke developing in the cabin. The aircraft returned to Helsinki for a safe landing on runway 22L about 12 minutes after departure.
Passengers reported they had been advised there might be some steam off the air conditioning system, however, after departure they smelt smoke first and saw intensifying smoke, while smoke detectors went off around the aircraft.
The airline reported the aircraft returned due to smoke detector indications, the passengers were taken to hotels. The cause is being investigated.
On Jan 6th 2022 Finland's Onnettomuustutkintakeskus (AIBF) reported de-icing glycol ended up in the wrong place, the auxiliary power unit (APU). The airline continues investigation, the AIBF did not open an investigation.
