Computer glitch led to Airbus nosedive
Julian Walsh, chief air investigator at the Australian Transport Safety Bureau, said an initial investigation indicated the cause was a computer unit that detects through sensors the angle of the plane against the airstream. One of the plane’s three air data inertial reference units, known as ADIRUs, malfunctioned and sent the wrong data to the main flight computers.
He said Airbus had notified all operators of A330 and A340 aircraft, equipped with the same sensors, about how crews should respond to such a malfunction. But aircraft are unlikely to be grounded over a malfunction that had never happened before, he added.
