Flight QZ8501 plunged into the ocean in stormy weather on December 28, during what was supposed to be a routine flight from the Indonesian city of Surabaya to Singapore.

The crash of the Airbus A320-200 triggered a huge international search, with ships and aircraft from several nations involved in a lengthy hunt that was hampered by strong currents and bad weather.

The bodies of 56 of those who died have never been found. In their final report into the accident released today, Indonesia's official National Transportation Safety Committee said poor maintenance and a fault with the system that helps control the rudder's movement was a major contributing factor to the crash.

Investigators said there was miscommunication between the pilots as the plane plunged towards the sea, with the men at one point pushing their control sticks in opposite directions.
