The final investigation report of the Malaysia Airlines flight MH17 that crashed in Ukraine last year is expected to be published early October, the Dutch Safety Board said on Thursday.
"For the investigation, we are following International Civil Aviation Organisation rules," a Dutch Safety Board spokesperson told Xinhua.
The Netherlands is leading the international investigation into the crash with accredited representatives from Australia, Malaysia, Russia, Ukraine, Britain and the US.
The report is said to pin some blame on Malaysia Airlines because it did not review other countries' warnings and was unaware of conflict zones that other airlines were avoiding.
A total of 298 people, 196 of them Dutch, were killed after aircraft crashed in the Donetsk area of east Ukraine.
A preliminary report published last September said the plane "broke up in the air probably as the result of structural damage caused by a large number of high-energy objects that penetrated the aircraft from outside".
