A Regional 1 Airlines de Havilland Dash 8-100, registration C-FRIB performing flight TSH-441 from Fort Mackay Albian,AB to Edmonton,AB (Canada) with 38 people on board, was climbing through 15,000 feet out of Fort Mackay's Albion Airport when the crew noticed a vague burning odour on board, which was shortly followed by the #2 bleed air hot indication cycling on and off. The crew worked the associated checklist, turned bleed air system #2 off and requested FL200 instead of FL240. After the aircraft levelled off at FL200 the #1 bleed air hot started to illuminate and extinguish repeatedly. Again the associated checklist was performed resulting in the shutdown of the #1 bleed air system. The crew declared emergency reporting smoke in the cockpit and initiated a descent to 8000 feet due to the loss of pressurization. The aircraft landed safely on Edmonton's runway 20 about 75 minutes after departure.

The Canadian TSB reported that the crew initiated a "moderate descent" to 8000 feet due to the loss of pressurization. It was suspected that de-icing fluid in the engine intakes was the source of the odour. The bleed systems are being investigated by maintenance.
