PD246 - Incident: Porter DH8D at Toronto on Jul 5th 2022

A Porter Airlines de Havilland Dash 8-400, registration C-GLQB performing flight PD-246 from Toronto City,ON to Thunder Bay,ON (Canada) with 67 passengers and 4 crew, was climbing through 16000 feet out of Toronto's Billy Bishop Airport when the crew heard a popping noise and detected an electrical odour. The crew worked the related checklists and decided to divert to Toronto's International Airport, where the aircraft landed without further incident. The aircraft vacated the runway, stopped on the taxiway and commenced a rapid deplanement.

The Canadian TSB reported maintenance determined the #1 air cycle machine had failed and replaced it.
