Incident at Yellowknife, NT


1999-04-07: C-FATW, a Beech C90 King Air, was on a medevac flight from Yellowknife to Fort Liard when the crew reported a problem with the right engine. They shut down the affected powerplant and indicated that they were returning to Yellowknife. The crew carried out an uneventful single-engine landing at 1955Z with ERS on standby. There was minimal disruption to normal operations at the airport. OPI - Maintenance and Manufacturing UPDATE M. & M. reported that the crew noticed right engine fluctuations and rising T5 temperatures, so they shut down the engine. Maintenance determined that the problem was a seized fuel control unit, which had about 4,000 hours since overhaul. Due to the seizure, the high pressure pump, fuel control unit and pump to control unit coupling were replaced. The company uses a computerized reliability program and the data has been captured for assessment of trends. An SDR has been submitted to Transport Canada. There had been no indications of impending failure of the unit prior to the occurrence.
