| Executive Summary: | Saturday, 7 August 1999, Flight British Airways 8412 from Birmingham to Geneva (operated by Maersk Air UK) was initiating the descent from FL370 towards the destination airport when the cabin crew recognized smoke and an acrid smell in the cabin. The commander issued a pan-pan-pan message and started a rapid descent. 12 minutes later the aircraft was landed uneventfully on runway 23 in Geneva. The 40 passengers and the crew evacuated the aircraft via the forward passenger door over the inflated slide. Nobody was injured and no damage resulted to the aircraft The incident was caused by engine oil, penetrating the air conditioning system through the right-hand high pressure bleed air port, that evaporated and formed a smoke-like aerosol in the passenger cabin. |
