Narrative:
The Antonov 2 biplane was destroyed when it impacted terrain near Novopokrovskoye, Russia during an aerial application flight. Both occupants were killed.
The aircraft was contracted to carry out agricultural operations starting at the end of April 2016. A captain, co-pilot and technician were assigned to the aircaft. On June 20, 2016 the co-pilot left the crew without explanation of the reasons. This posed a problem for the captain, as agricultural flights may only be carried by two pilots. In violation of this, the captain started carrying out flights on his own. On June 29, an acquaintance of the pilot and a former AN-2 pilot, flew along. On June 29 and June 30 eyewitnesses noticed that both men were consuming alcoholic beverages between flights.
The accident happened on the fifth flight of the day. The aircraft impacted terrain during a turn. A fire developed, which consumed the aircraft.
It was established that turns were executed at bank angles of about 40°, which exceeded the allowed 30°. Furthermore, the flight was executed at altitudes of 20-40 m where the limit was 50 m.

The accident of the AN-2SX RA-33462 occured when operating on an agricultural flight, is most likely due to an error in piloting technique, expressed in an unintentional descent when performing a turn, resulting in the collision of the aircraft with the ground surface in a controlled flight.
Contributing factors:
- PIC's lack of flight training on agricultural flights without a co-pilot;
- performing a flight by the PIC with passenger as a co-pilot;
- the presence of alcohol in the body of the PIC and the passenger;
- the possible transfer of control of the aircraft to the passenger, a former pilot of the An-2;
- violation of the An-2 Airplane Flight Manual and FAP-128 height-keeping, roll on turns and speed when performing agricultural flights;
- the lack of controls on the part of the administrative board of Krasnokutske Flight School of Civil Aviation of flight operations on agricultural flights on operational points.
