Occurrence
On 28 April 2020, Buffalo Airways Ltd. Beechcraft King Air A100 aircraft (registration C-FCBZ, serial number B-116) was conducting charter flight BFL666 under instrument flight rules from Cambridge Bay Airport, Nunavut, to Kugaaruk Airport, Nunavut. On board were two flight crew members and freight. At 1350 Mountain Daylight Time, during daylight hours, the aircraft landed at Kugaaruk Airport on Runway 23. Immediately after touchdown, the aircraft veered to the right and departed the runway surface. It came to rest after colliding with a snowbank on the northwest side of the runway.
Damage and Injuries
The two crew members were not injured and egressed the aircraft via the main cabin door. There was no fire, but the aircraft sustained substantial damage. The 406 MHz emergency locator transmitter did not activate.
Investigation
The Transportation Safety Board of Canada conducted a class 3 investigation, which analyzes a small number of safety issues and may result in recommendations. The investigation found that a continued approach below required aerodrome operating visibility led to the runway excursion.
