Incident at YELLOWKNIFE NT (CYZF)
2001-08-31: UPDATE Maintenance and Manufacturing reported that shortly after takeoff the flight crew shut down the # 1 engine due to backfiring and loss of power. This was a precautionary shutdown as the loss of power and the propeller not feathered created a large amount of drag which affected climb performance. Upon return to the maintenance facility, the carburetor was replaced and the a/c ground-checked as serviceable and it was returned to service. This was a relatively high-time engine (approximately 1200 hours TSO). The company has removed the engine and sent it for overhaul, and a zero time engine was installed. The reason for removal was that the company suspected that the valve cam may have been worn enough to cause a valve timing problem and backfiring. Replacement removed the risk of further incidents and ensured a greater margin of safety.
2001-08-17: UPDATE TSB reported that during rotation at takeoff, the number 1 engine (P & W R-2800) backfired and lost power. The engine was shut down. Emergency services were requested and the crew returned and landed on Runway 27. The aircraft was shut down on the runway and towed to the ramp. The carburettor was changed and the aircraft then returned to service.
2001-08-17: BFL 315, a C46, departed Runway 33 at Yellowknife at 2019Z and the crew reported an engine out at 2020Z. They returned and landed safely on Runway 27 at 2023Z. The crew was unable to taxi the a/c, so they were towed clear at 2037Z. CFR was on standby. One aircraft was delayed 15 minutes taxing to the west side of the airport.
