Faulty equipment and the crew's "inability to control the aircraft" led an AirAsia A320 to crash into the Java Sea last year, killing all 162 people onboard, a report said on Tuesday. Flight QZ8501 went down in stormy weather on December 28, during what was supposed to be a short flight from the Indonesian city of Surabaya to Singapore. In their final report into the accident released Tuesday, Indonesia's official National Transportation Safety Committee said a major factor was a fault with a system that helps control the rudder's movement.
