Data Recorder, a Cockpit Voice Recorder, and a Quick Access Recorder has now ruled out an engine control failure, and examination of the engines "indicated no evidence of a mechanical defect or ingestion of birds or ice", the AAIB did...

Fuel 'air bubbles' caused crash From This is London Air bubbles in the fuel of a British Airways Boeing 777 could have caused it to crash land at Heathrow, according to investigators. It comes as the evacuation procedure used after the plane crashed last month was criticised for causing a dangerous fuel leak that could have proved fatal. The Air Accidents Investigation Branch has focussed on the plane's high-pressure fuel pumps, after a study found they were damaged. fuel pumps revealed signs of abnormal cavitation (air bubbles) on the...
