| Confidence Rating: |  Accident investigation report completed and information captured |
The aircraft was climbing through 15,000 feet after departure from London Heathrow (LHR) when it was reported that an electrical burning smell, smoke and haze, was apparent in the cabin. The crew obtained clearance to return to LHR and, after carrying out the ‘smoke and fumes’ checklist, the problem was alleviated. The aircraft landed without further incident.
A small section of wiring within the cabin ceiling lighting harness was found to have been the source of the smoke and fumes. Damage to the harness was found to have been caused by an electrical event leading to arcing between two of the insulated wires within the harness. The exact nature of this event could not be determined.
