Weather conditions for Paulatuk included a strong crosswind at 25-30 knots and blowing snow. The pilot attempted to carry out an overshoot, but the left wing contacted the ground and the aircraft cartwheeled. This happened during a transition from visual to instrument flight. The aircraft was overloaded by 840 lb. FINDINGS: 1.The Paulatuk aerodrome runway is not oriented to correspond with the prevailing winds.; 2. Environment Canada does not produce an aerodrome forecast for Paulatuk.; 3. As the aircraft landed, the cross-wind from the right increased appreciably reducing visibility in blowing snow.; 4. During the overshoot, as the pilot was making the transition from visual to instrument flight conditions, control of the aircraft was lost.; 5. The aircraft was overloaded.”
