Accident: Buffalo DC3 near Hay River on May 3rd 2019, forced landing after engine failure
A Buffalo Airways Douglas C-47A Skytrain (DC-3), registration C-GJKM performing flight J4-169 from Hay River,NT to Yellowknife,NT (Canada) with 2 crew, was enroute about 20 minutes into the 55 minutes flight when the right hand engine failed. The crew attempted to return to Hay River, however, had to perform a forced landing in open terrain around about 08:00L (14:00Z). The crew remained uninjured, the status of the aircraft is currently unknown (unverified preliminary information suggests the aircraft received damage beyond repair).
The Canadian TSB is looking into the occurrence to decide whether to deploy investigators on site.
The airline reported the cause was a mechanical fault, both crew are safe.
