Incident at YELLOWKNIFE NT (CYZF)

Summary

2001-07-09: BFL 308, a C-46, had departed Yellowknife for Cambridge Bay at 1331Z but had to return because the crew had shut down one engine. The crew requested priority but did not declare an emergency. Emergency vehicles were called out. C-GDPB, a medevac flight, was delayed about 10 minutes because of the occurrence but the pilot said he was not a priority and it was no problem. BFL 308 landed safely at 1516Z and operations returned to normal.
2001-07-10: UPDATE TSB reported that the number 1 engine (P & W R-2800) on the Curtiss-Wright C46D began to ""pop"" intermittently about 130 NM north of Yellowknife. The flight diverted back to Yellowknife, and the crew secured the engine approximately 30 NM north of the airport. They requested priority but did not declare an emergency, and the landing was accomplished without further incident, with AFF standing by. Maintenance personnel traced the problem to a stuck valve. They changed the applicable cylinder and returned the aircraft to service.
