QantasLink changes air quality training, procedures after 717 crew incapacitation

An air quality event aboard a QantasLink Boeing 717-200 saw the aircraft land in Hobart with both flight crew affected by hypoxia-like symptoms. The incident has seen National Jet Systems, which operates under the QantasLink brand, update training and safety guidance about cabin air quality issues, according to the Australian Transport Safety Bureau. On 6 June 2023 the aircraft, VH-NXM, was operating a service from Sydney to Hobart, on the sland of Tasmania. After departing Sydney two cabin crew in the front of the cabin detected a “strong chlorine odour” near the forward galley. They reported this to the flight crew, who had not detected the smell. At cruising altitude, the crew conducted a company air quality event procedure. At 21:08 local time, about 10nm (18.5km) from Hobart at an altitude of 4,000ft, the captain and first officer noticed a chlorine odour, likely coming from the air-conditioning vents. “About 30 seconds later, while the flight crew were configuring the aircraft for landing on runway 30, the captain noticed quickly developing adverse effects on vision, mental capacity, and movement, and self-assessed as unable to safely fly the aircraft,” says the enquiry. “The captain later described the symptoms as fogginess of thought, confusion, deteriorating situational awareness, weakness and tingling in the arms and legs, and narrowing of vision.” The captain transferred control to the first officer, who saw that the captain looked pale, but not incapacitated.
