B747 enroute London to Toronto advised of Smoke in the Cabin. Flight diverted to Goose Bay and landed safely 1741z. More details to follow. TSB Case Closed. Update: The flight crew isolated the Electrical power to the forward Galley area. When the odor did not dissipate, the flight crew requested and received clearance to divert to Goose Bay. It is unclear whether the flight declared an emergency. On descent through FL290
the Flight Attendant reported that the Electrical burning smell had gone away and that the odor remaining was similar to the cleaning fluid they use on the Galleys. The aircraft continued to Goose Bay and landed uneventfully 1741z. Emergency Services were invited on board the aircraft and they reaffirmed that there was no Electrical or Smoke odor present. It was later reported that the Crew located an open bottle of strongly scented mouthwash in the forward Galley area. The mouthwash contained Dettol which is the suspected source of the smell. Maintenance carried out a complete check of the electrical system and no faults were found. As a precautionary measure, the oven was disabled and removed. It will be subjected to a complete inspection at he Air Canada base in Montreal. The Aircraft departed Goose Bay later that same evening and completed the flight to Toronto. TSB File # A99A0108.
