Investigators have downloaded information from the flight-data recorder of the Malaysia Airlines Boeing 777-200ER that crashed in eastern Ukraine.
While the recorder was "slightly" damaged, says the Dutch Safety Board, its memory unit was intact.
"Furthermore, no evidence or indications of manipulation of the recorder was found," it adds.
Its information has been downloaded and the inquiry says it contains "valid" data from flight MH17. This information will be combined with that from the cockpit-voice recorder, data from which was retrieved on 23 July.
Specialists from the UK Air Accidents Investigation Branch are conducting the examination of the recorders on behalf of the Dutch Safety Board.
