United Kingdom investigators are to start examining the flight data recorder from the downed Malaysia Airlines plane.
The Air Accidents Investigation Branch in Farnborough will start the process almost a week after the plane crashed in eastern Ukraine.
All 298 people on board flight MH17 were killed in the crash in Ukraine on 17 July.
British accident investigators will attempt to retrieve data from the recorders following a request by authorities in the Netherlands.
The data recorder records technical information on the performance of the aircraft.
The other box takes down sounds such as pilots’ voices and, potentially, an explosion.
