Circumstances:
The crew was returning to Yellowknife on a flight from Shepard Bay. En route, the crew became lost and after multiple attempts to establish their location, did a controlled ditching (at night) into a lake in the Thoa River area. The crew was unable to get to shore due to the water temperature and sat on the extended flaps, just 3 feet above the water surface. After 2 days the Captain died from exposure but the Co-pilot remained alive until rescued 10 days after the accident.
Probable cause:
The crew became lost in flight.

Captain / Total flying hours:

Circumstances:
Shortly after takeoff from Yellowknife Airport, the twin engine aircraft encountered serious difficulties to gain height. It then hit a building and crashed. Both crew members who were performing an on-demand cargo flight were killed.
Probable cause:
It was determined that the total weight of the aircraft was 1,400 pounds above the MTOW. Investigations revealed that the aircraft was parked on the ramp for six days prior to the accident and the crew failed to deice the plane before departure. No deicing, defrosting or contaminent removal was performed prior to departure. In such conditions, the aircraft failed to gain height due to a loss of lift, loss of aerodynamic performances and a subsequent overload.

Circumstances:
The ski-equipped C-47 attempted to depart from a 4200 feet long airstrip which was covered with five inches of snow. The crew had checked out the location to see if a C-54 could land there for resupply operations. During the night frost had accumulated on the aircraft. The windshield was cleared, but the wings and stabilizer were not. At a weight of 28850 pounds, 850 pounds over the allowable gross weight, the pilot tried to take off. After becoming airborne the right wing dipped. The pilot recovered, but the main gear then touched the ground. The wheels and skis then hit a river bank. The C-47 bounced and came down on the right wing, sliding to a stop in a tail high position. The wreckage was still on the same location by 2005.

Circumstances:
During the takeoff roll, the aircraft started to veer to the left, and although the report does not give a clear reason for this, it may have had something to do with the thick cover of about 10-15 cm of soft snow. This may have been slightly thicker on the left (downwind) side of the airstrip, causing more drag for the left main gear. The pilots fought hard to keep the aircraft on the narrow airstrip, but failed. The left main gear hit the base of a snow bank next to the airstrip, and a moment later the left propeller dug deep into that same snow bank. Because it was running very high power at that time (in an attempt to steer the aircraft to the right), the impact tore the entire #1 engine off the wing. Losing so much power on the left side so suddenly, with the right engine still running at reduced take-off power, caused the aircraft to make a violent left turn, completely destroying the left wing and tail boom. It then continued along the strip for another 150 meters and came to a stop, again to quote the report: "completely wrecked but in an upright position". There were no injuries.
