French investigators have called for a review of the design and maintenance of titanium alloy engine parts to ensure they guard against the risks of metal fatigue following an engine blowout on an Airbus A380 exactly three years ago. France’s BEA agency made the recommendation in a final report into the accident in which an Air France jet carrying more than 500 passengers lost the front section of one of its four engines while flying over Greenland, before landing safely in Canada.
