The Dutch safety board has officially taken formal charge of MH17 crash investigation.
The organisation claimed officials have so far been unable to gain access to the site as their safety has not been guaranteed.
An international team of 24 are to investigate the disaster, and probe whether the aircraft's black boxes have been tampered with.
Decisions involving flight routes and the availability of passenger lists will also be reviewed, the safety board said.
The bodies of 40 victims have arrived in Eindhoven.
The mother of the three Australian children killed on flight MH17 told a memorial service her "arms would always be reaching for them."
A woman has apparently posted pictures of herself on social media with mascara looted from the Malaysian Airlines flight MH17 crash site.
A large section of plane wreckage and everyday carry-on items like chocolates remain scattered among the wild flowers at the crash site.
