The causes of the Armavia-owned A-320 jet crash are expected to be announced today in an expanded statement. According to the International Aviation Committee, some items to the document will be added by the Armenian side. Earlier the Armenian aviation officials refuted the information that an explosion resulting from a criminal scuffle shocked the plane. The Armenian side adheres to the opinion that the crew was guilty of the crash. To remind, on early May 3 A-320 crashed over the Black Sea killing 113 people aboard.
