Descripción:
An Antonov 148-100E jet, registered 61708, was destroyed in an accident near Garbuzovo, Belgorod Region, Russia, killing all six crew members.
The airplane, operating on its 32nd flight, was used to train pilots of the Myanmar Air Force. The AN-148 was due to be delivered to Myanmar later that year.
Around 10:40 the aircraft broke up in flight. Parts of the aircraft, including part of the horizontal stabilizer with elevator, were found 2-3 km from the main crash site.

Probable Cause:

The cause of the accident was the inadvertently permitted the aircraft to accelerate 110 km/h above the design limit speed during an emergency descent.
This led to low-frequency vibrations on the aircraft in all axes, an increase of alternating accelerations exceeding the margin of safety. The result was the break up of the aircraft in the air, followed by its collision with the earth.
The main factors contributing to the accident were:
1) untimely and inadequate actions of the crew to control the emergency decent;
2) lack of proper coordination among the members of the crew;
3) deviations from recommendations in the flight manual in executing the emergency descent ;
4) misleading indications on basic instruments when outside characteristic operating conditions
