## Accidents and incidents

Perimeter Airlines has had five reported accidents.
* 1 November 1996, a Swearingen SA.226TC Metro II aircraft was on a scheduled flight (PAG207) to Gods River (ZGI) from Gods Lake Narrows (YGO). With about 345 ft (105 m) to the threshold of runway 27 the right hand main gear touched the ground and collapsed. After travelling about 20 ft (6.1 m) they hit a ridge of snow. The left gear touched down about 326 ft (99 m) ahead of the threshold and the aircraft went off the right side of the runway. The aircraft had two pilots and five passengers on board and there were no fatalities or injuries but the aircraft was a write-off.
* 11 or 12 October 2001, a Swearingen SA.226TC Metro II Perimeter Flight 962 arrived at Shamattawa on a MEDIVAC flight to pick up a patient. It was night and the aircraft was coming into runway 01 too fast and too high so the crew performed a missed approach. Flying to the left of the runway centreline the aircraft hit some trees and came to rest in some muskeg. There were three people on board, both pilots were killed and the third person required hospitalization.
* 8 November 2006, a Swearingen SA.226TC Metro II was touching down at Norway House. The crew selected propeller reverse and the aircraft turned to the left with the main tire making contact with some loose snow. The aircraft next went over a ditch and climbed an embankment where the landing gear collapsed. The seven passengers and two crew evacuated the plane safely but it was a write-off.
* On 23 December 2012, a Swearingen SA227-AC Metro III passenger plane with nine people aboard, operated by Perimeter on behalf of Kivalliq Air crashed at Sanikiluaq Airport (YSK) in Sanikiluaq, Nunavut, killing an infant boy and injuring all the others. The aircraft was on a second approach at the time.
