Incident at YELLOWKNIFE NT (CYZF)
2001-04-26: C-FASN, a Beech King Air, departed Yellowknife on a flight to Kugluktuk and the crew subsequently reported an engine shut down, and returned and landed without further incident with CFR on standby. No other a/c were affected.
2001-04-30: UPDATE Maintenance and Manufacturing reported that shortly after takeoff, the crew noted L/H engine oil pressure fluctuations, so engine power was reduced and the L/H torque indication began to fluctuate rapidly. The Captain observed the L/H engine venting oil from the overboard oil vent line. The engine was shut down and the aircraft returned to Yellowknife. Upon inspection by maintenance it was discovered that the L/H engine compressor seal had failed, pressurizing the engine internally which caused the oil to dump overboard via the oil vent tube. An SDR has been submitted. A Garrett approved representative is on his way to Yellowknife at this time to complete a field repair of the engine.
