Narrative:Perimeter Flight 962 had departed God's Lake Narrows for a short 27 minute medevac flight to Shamattawa to pick up a patient. The crew were flying a night time approach to runway 01 when they carried out a missed approach because they were too high and too fast. The aircraft flew into trees slightly to the left of the runway centreline in a muskeg area about 2600 feet from the departure end of runway 01. A post-crash fire was confined to the wings which had separated from the cabin and cockpit wreckage.
FINDINGS AS TO CAUSES AND CONTRIBUTING FACTORS:
1. The aircraft was flown into terrain during an overshoot because the required climb angle was not set and maintained to ensure a positive rate of climb.
2. During the go-around, conditions were present for somatogravic illusion, which most likely led to the captain losing situational awareness.
3. The first officer did not monitor the aircraft instruments during a critical stage of flight; it is possible that he was affected by somatogravic illusion and/or distracted by the non-directional beacon to the extent that he lost situational awareness.
