NTSB narrative
On 22 December, 2012, at approximately 2313 UTC time, a Swearingen SA227-AC Metroliner, registration C-GFWX, was operated by Perimeter Aviation as chartered flight number PAG993, from Winnipeg, Manitoba (CYWG) to Sanikiluaq, Nunavut (CYSK). During the second approach to the airport, the aircraft touched down hard and overran the end of the runway. The aircraft came to a stop approximately 150 to 200 meters past the end of the intended runway surface. The flight crew sustained serious injuries, 6 passengers sustained minor injuries and one passenger, an infant, was fatally injured. The aircraft was substantially damaged.
The investigation is being conducted by the Transportation Safety Board of Canada. The NTSB has appointed an Accredited Representative to assist the investigation under the provisions of ICAO Annex 13 as the State of Manufacture and Design of the airplane.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- No bulk values were replaced by the NTSB case API.
- The date is the UTC date the NTSB stores; the local time zone is not recorded, so the local date may differ by a day.
