Relatives of the passengers on-board will be informed of the document’s conclusions, before the official release on October 13.

“Prior to the official publication of the report, the relatives will be informed about the conclusions of the investigation during a closed information meeting,” the Dutch Safety board said in a statement.

“In September, the relatives will receive an invitation to the information session containing details of the location, the time and how they can register.”

Among the 298 people on board MH17 when it crashed on July 17, were 39 Australians.

The plane is believed to have been shot down as it travelled over conflicted territory in the Ukraine.

Russian and Ukrainian forces had been fighting for control of the Crimean Peninsula, a strip of disputed land within Ukrainian territory.

Western authorities have blamed Russian-backed rebels for the downing of MH17.

But neither Kiev or Ukrainian forces have claimed responsibility.
