Incident Overview
The crew of C-GKBN, a Beechcraft 200 Super King Air carrying five passengers, conducted a straight-in approach to a snow-covered and icy runway at Hamburg, Alberta, Canada. The aircraft was configured with approach flap settings for landing. Upon touchdown in approximately two inches of snow, directional control was lost. The aircraft turned sideways on the strip, struck a snow windrow, which then pulled the aircraft off the runway into a stand of trees.
Landing Conditions
The landing was performed by the First Officer. The aircraft had accumulated about 1/8 inch of ice on the approach. Approach flap was used instead of landing flap during the landing sequence. A five-knot tailwind was present at the time of landing, and the touchdown was reported to be very firm.
Aftermath and Examination
No injuries were reported; however, the aircraft sustained substantial damage. Company representatives who examined the runway surface after the accident discovered a rut running diagonally across the runway. The rut was apparently present prior to the landing and may have contributed to the loss of directional control.
