Sixty seven people were on board Azerbaijan Airlines flight J2-8243 when it crash landed just short of Aktau airport in Kazakhstan on Christmas Day.
Footage showed the passenger plane nose diving before slamming into the ground, erupting in a fireball and killing 38 people.
In the days that followed, claims emerged that the plane's navigation systems had been compromised and the plane had been shot down, possibly confused with a Ukrainian projectile by ground artillery in Chechnya.
Local media cited government sources in suggesting jammers had 'paralysed' the plane's communication systems. Russia tried to play down speculation.
A preliminary report later uncovered fragments from a Pantsir-S missile lodged in the plane. The crew had reported losing GPS aids due to jamming.
