History
On 2 June 2017, a TVS-2MS aircraft (RA-2099G) owned by FSUE SibNIA was scheduled for a demonstration flight from Chinggis Khaan Airport in Ulaanbaatar, Mongolia, to Eroo. The crew consisted of two pilots, two technicians, and eight passengers. The aircraft had been refueled to 1,150 liters of fuel. Preflight preparation was conducted by the captain approximately three hours before departure. The originally planned departure time of 04:00 UTC was delayed due to passenger arrival, and the actual takeoff occurred at 07:18 UTC. The flight was conducted under visual flight rules in simple weather conditions during daytime.
Damage
During the takeoff roll, the aircraft experienced an accident and sustained significant damage. No fire occurred at the accident site. All crew members, passengers, and other persons were uninjured.
Investigation
The accident was reported to the Interstate Aviation Committee (IAC) on the same day. The Mongolian Aviation Accident Investigation Bureau delegated the investigation to the IAC. A commission was formed, including representatives from the IAC, the West Siberian Territorial Administration of Rosaviatsia, and SibNIA. The National Transportation Safety Board of the United States was notified as the state of manufacture of the engine.
Notes
A preflight medical examination was not performed, as permitted by relevant regulations for airports without medical personnel. The captain conducted a health inquiry among the crew and recorded no complaints.
