Files erased from three engines of an Airbus A400M could be the cause of a Spanish military plane crash on May 9 in Seville.
The machine’s engines failed minutes after takeoff killing four of the six-crew members on board.
According to Reuters, crucial data files were missing from three of the four engines of the €20 billion aircraft, leaving the turboprops unoperational.
In a statement, Airbus said: "CITAAM confirmed that engines 1, 2 and 3 experienced power frozen after lift-off and did not respond to the crew’s attempts to control the power setting in the normal way, whilst engine 4 responded to throttle demands."
The missing files, known as "torque calibration parameters", are believed to have been erased during a software upgrade carried by Airbus.
The UK and other European NATO members cancelled their A400M orders following the incident.
Spain prohibited Airbus from flying any A400M model, leaving the manufacturer grounded with dozens of scheduled test-flights.
