A Westjet Boeing 737-700, registration C-FWBX performing flight WS-167 from Calgary, AB to Edmonton, AB (Canada) with 116 people on board, was climbing out of Calgary’s runway 16 when the purser detected a burning smell and haze in the mid cabin. The flight crew levelled off at about 8000 feet, declared emergency repoting smoke in the cockpit and returned to Calgary for a safe landing on runway 28 about 10 minutes later.
The Canadian TSB reported that maintenance identified a problem with the Live TV system, further troubleshooting is underway.

All commercial jets (with the exception of the 787 Dreamliner) rely upon air pulled in through the engines to provide pressurized air to the cabin. During flight high-temperature compressed air is bled off the engines and, after being cooled, is re-circulated throughout the cabin and flight deck. Pyrolized engine oil or hydraulic fluid may contaminate the air in these compressors. As a result of exposure to this contaminated air, airline workers along with airline passengers, may develop chronic health problems leading them to seek attention from health care providers.
If you have been exposed to contaminated air on an airplane there is important information that your doctor should know. Click here to obtain the Bleed Air Medical Protocol, a document designed to help doctors treat victims of fume events. Bring this document to your doctor.
