General Electric has asked airlines to inspect all CF6-80E1 engines after Canada 3000's first Airbus A330-200 was forced to make a precautionary diversion on its inaugural flight. The diversion followed the discovery of an oil leak in the number four bearing area. GE says the aircrew, who were flying from Toronto to Vancouver, reduced the engine power to idle and diverted to Winnipeg when they observed "indications of a low quantity of oil" in one engine.
On landing at Winnipeg, it was discovered that an oil leak had developed in the "D-sump" which acts as a reservoir for the number four bearing. The engine, which is believed to have amassed only 29h on wing at the time of the incident, was removed and transported to overhaul shops in Ontario.
