Preliminary version of reasons that could have caused Il-76 aircraft owned by Silk Way airway company to crash in Afghanistan has been announced.
Chairman of the investigative committee set up to probe causes of the crash said it is unlikely that the crash occurred due to interference of illegal forces, according to sources in the State Civil Aviation Administration.
Black boxes of the aircraft were sent to Moscow to be deciphered on 15 August.
The black boxes are being examined in accordance with the article 13 of International Aviation Convention involving representatives of Afghan authorities and investigative committee.
Investigative materials and a report will be handed over to aviation leadership of Afghanistan as soon as the work completes.
The crash occurred on 6 July 6 at 00.10 Kabul time. The same day spokesman for the US-led coalition forces in Afghanistan British Maj. Tim James reported that the plane crashed into a mountain at an altitude of about 3,800 meters. However, a number of Afghan media reported that the plane was shot down by Taliban.
