A Brussels Airlines Airbus A330-200, registration OO-SFZ performing flight SN-552 from Toronto,ON (Canada) to Brussels (Belgium) with 251 passengers and 10 crew, was climbing out of Toronto shortly after takeoff, when a number of passengers and cabin crew located in the aft cabin began to feel unwell, no odour, fumes or visible smoke were detected. Cabin crew reseated the affected passengers into the forward cabin, the affected cabin crew were administered oxygen and recovered. The flight continued to Brussels for a safe landing. Medical services awaited the aircraft and examined the affected passengers and crew.

Cabin crew reported they suffered from nausea, palpitations, headache and abnormal blood pressure, they felt a metallic taste.

The Aviation Herald learned of the occurrence on Nov 30th 2017 and contacted the airline. A first reply on Dec 1st indicated that more time was needed, the airline reported past the weekend on Dec 4th, that 5 passengers and 4 cabin crew in the aft cabin, only a few seat rows were affected, felt unwell shortly after departure as if there was lack of fresh air, no (oil) smell or fumes were present in the cabin. Cabin crew reseated the passengers in those seat rows in the front of the cabin, where no such air flow issue existed the passengers recovered. The cabin air flow rate was increased as well. A doctor examined the affected after arrival in Brussels, all passengers continued their journeys. The crew were sent to an aviation medical service for examination, tests were conducted. The aircraft was examined involving Airbus into the troubleshooting, it was concluded the lack of air flow was probably the result of a temperature sensor in the cabin that malfunctioned due to dust in its surrounding (air supply filters). Due to the wrong measurement as result of the dust the sensor instructed the air conditioning system to reduce the air flow. There had been a similiar occurrence in another (non Brussels Airlines) aircraft before.

Belgium's Mobility (AAIB) have so far not responded to an inquiry by The Aviation Herald.

The occurrence aircraft remained on the ground for 31 hours, then returned to service.
