Concorde tests found 'engine risks'
![]() Air France Concordes are still grounded
A study of Concorde's engines carried out before last month's fatal crash in France found 55 "significant risks", according to New Scientist magazine.
New Scientist says BA commissioned the risk analysis because it wanted to keep the 30-year-old plane flying until 2012. BA has played down the results of the tests, saying its Concorde fleet had been undergoing a programme of "entirely routine" checks and regular improvements. 152 potential risks An inquiry is currently under way to establish why an Air France Concorde crashed two minutes after taking off from Paris on 25 July, killing all 109 crew and passengers, and four people on the ground.
Experts are said to have identified 152 separate risks, 55 of which were considered significant. No details are known about the exact problems. The implications of potential failings were divided into five categories - ranging from "trivial" to "catastrophic". Catastrophic consequences included multiple engine failure and uncontrolled fire. 'A one in a billion chance' A spokeswoman for BA said the risk analysis study was one routinely carried out on all aircraft as well as Concorde. She said: "New Scientist are referring to a continuous improvement programme carried out on all our aircraft, designed to recognise the best and the future technological advances. "The Civil Aviation Authority looked at the programme and the findings and did not find any need to demand action to improve the safety of the aircraft." The use of the word risk in engineering meant there was "a one in a billion chance of that component failing", she added. Concorde is one of the most rigorously tested aircraft in the history of aviation. Until last month's crash it had an unblemished safety record.
