Jazz DH8C at Vancouver on Mar 6th 2014, heated cabin

A Jazz de Havilland Dash 8-300, registration C-GMTA performing flight QK-8416 from Vancouver,BC to Kelowna,BC (Canada) with 52 people on board, was climbing out of Vancouver when the crew stopped the climb reporting an unusual cabin heat and requesting emergency services on stand by for the arrival. The aircraft returned to Vancouver for a safe landing about 20 minutes after departure.

The Canadian TSB reported the crew received a cabin duct temperature warning with temperatures above 100 degrees C. The cabin temperature could not be controlled, a blue hue and oil smell was observed in the cabin. The crew donned their oxygen masks and returned to Vancouver.
