YANGON, July 19 (Xinhua) -- Myanmar has found out the cause of the June 7 military plane crash, blaming adverse weather for the main reason of the accident, according to a statement of the office of the commander-in-chief of the Defense Services issued Tuesday night.
Based on the weather report and the two black boxes, flight data recorder and cockpit voice recorder, that were retrieved on June 18, the accident was found out to have occurred due to loss of control after experiencing irregular weather.
It caused the plane to stall or lose the ability to attain lift, resulting in a spin or nose dive, according to a third party investigation group involving Australian technicians.
The investigation and analysis concluded that the aircraft had crashed due to adverse weather condition and not from any act of sabotage, explosion or engine failure.
No equipment malfunction of any part of the plane up to the crash time, the statement said, however adding that while en route from Myeik to Yangon, the wind speed increased gradually, then the heating system to heat both wings was activated in order to fly through the cloud.

With a load of 2.4 tons of cargo and 122 people aboard, including 108 military personnel and their family members and 14 crew members, the aircraft lost contact with the ground shortly after taking off from Myeik on June 7.
