SW4, vicinity Red Lake ON Canada, 2013

Summary

On 10 November 2013 the left engine of a Fairchild SA227 on final approach suddenly ceased to produce any power at approximately 500 feet whilst continuing to operate. The crew did not identify what had happened in time to avoid losing control of the aircraft which then impacted terrain, caught fire and was destroyed. The Investigation found that premature failure of engine components had caused the engine malfunction and noted that some pilots may believe that the Negative Torque Sensing (NTS) System provided for the engines on this aircraft type will always detect high drag conditions arising from power loss.

Description

On 10 November 2013, a Fairchild SA227-AC Metro III (C-FFZN) being operated by Bearskin Lake Air Service on a scheduled passenger flight from Sioux Lookout to Red Lake was within sight of and on the extended centreline of runway 26 at its destination after completing a VOR/DME (GNSS) non-precision approach when, with only a few hundred feet of descent to go, it departed from controlled flight and crashed approximately 700 metres south of the runway threshold. A combination of impact damage and a post-crash fire destroyed the aircraft with five occupants killed, one sustaining serious injuries and one minor injuries. Damage caused to overhead power and communications lines severed these services to the airport and the adjacent community.
