Boeing 747-436, G-CIVB
The engines were being started during pushback when fumes and smoke were noticed in the cabin. The commander decided to return to the stand; however, there was some delay while the tug was reconnected. The intensity of the fumes increased and as the aircraft came to a halt on the stand an emergency evacuation was carried out. An extensive engineering investigation after the event was not able to provide any explanation for the origin of the fumes. The aircraft was returned to service and no further instances have occurred. This serious incident occurred in the USA. In accordance with Annex 13 of the ICAO Convention on Civil Aviation, an investigation would normally be carried out by the State of Occurrence. On this occasion, it was agreed with the NTSB that it would be more appropriate for the State of the Operator, ie the UK, to conduct the investigation.
