Narrative:
An Antonov TVS-2MS aircraft impacted the ground during takeoff from Ulan Bator-Chinggis Khaan International Airport in Mongolia. The ten occupants were not injured, but the aircraft was substantially damaged.
The aircraft was on a sales trip to Mongolia at the time of the accident. Eight passengers were due to be taken on a flight out of Ulan Bator. The aircraft was fueled with 950 kg of fuel.
Flaps were set at 20°, according to the crew, and the aircraft was cleared for takeoff from runway 32. After lifting off the runway, the aircraft went into an immediate climb and flaps were retracted at an altitude of 40-50 m.
Shortly afterwards the aircraft pitched up and entered a right bank with increasing roll rate. The aircraft lost altitude and impacted terrain between the runway and the taxiway. The right main gear and lower and upper right wings impacted the ground first, causing the undercarriage and wings to collapse.

The TVS-2MS was an Antonov 2T that was converted in 2013 with a TPE331 turbine engine instead of the original Shvetzov ASH-62IR radial piston engine.
