Air safety bosses order plane changes after Airbus crash

Airlines were today ordered to replace hundreds of crucial instruments of the type suspected as a cause of last month’s Air France Airbus crash that killed all 228 on board.

Investigators have focused on the possibility that the external speed sensors on the A330, known as pitot tubes, iced over and gave false readings to the plane’s computers as it ran into a thunderstorm off the coast of Brazil.
