The final report about what caused a Malaysia Airlines plane crash last year is expected to be published by the Dutch Safety Board on Tuesday. <br /><br /> Flight MH17 broke up high over eastern Ukraine in territory held by pro-Russian rebels last July killing all 298 people on board, mostly Dutch citizens. <br /><br /> Victims’ families will be the first to know the findings of the investigation at a Dutch military base where parts of the plane have been reconstructed. <br /><br /> The Dutch prime minister will then hold a news conference. <br /><br /> The report is expected to conclude the plane was brought down by a Russian-made BUK missile, but under rules governing flight crash investigations, the board is not authorised to apportion blame. <br /><br /> A preliminary report issued last year said the Boeing 777 flying from Amsterdam to Kuala Lumpur likely was hit by multiple “high-energy objects from outside the aircraft,” fuelling widespread speculation that it was downed by a surface-to-air missile, likely a Russian SA-11 system
