"The Dutch Safety Board (OVV) informed relatives and the accredited representatives to the investigation that the board will publish the final report on the investigation into flight MH17 on 13 October 2015," the board said in a statement.
"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 OVV added.
The passenger jet was shot down over Ukraine on July 17 last year, during heavy fighting between government forces and pro-Russian separatists. All 298 people onboard -- mainly Dutch -- were killed.
The OVV is charged with looking into the exact cause of the crash but will not identify those responsible.
