Incident at Vicinity of Koala, NWT

Summary

1997-07-08: The HS 748 was enroute from Yellowknife to Gjoa Haven with 29 people on board, at 15,000 feet when the cabin and cockpit began to fill with smoke. The crew declared an emergency and initiated an emergency descent. The crew then proceeded to Koala which was about 12 miles west. The starboard spill and dump valves were opened to try to dissipate the smoke, without success as the spill valve was jammed. The a/c landed at Koala about 7 minutes after the smoke was first detected. Inspection determined that the port supercharger had failed and that a piece of metallic debris had blocked the spill valve. The passengers were examined by a nurse at Koala and there were no injuries.
