Accident Details
On 8 July 2009, at an unspecified time of day, a Mil Mi-2 helicopter with registration RA-20413 operated by ZAO Smolenskaerotrans was conducting a pipeline survey flight. The aircraft was flying in simple meteorological conditions during daylight hours. On board were the commander and three representatives from the LPU MG (gas pipeline management unit).
Flight Sequence
Takeoff from Smolensk-Yuzhny airfield to the Divasy helipad occurred at 09:25. After picking up the representatives at Divasy, the helicopter departed at 10:55. The planned route was from Divasy, following the pipeline towards Dukhovshchina at a true altitude of 50 to 100 meters, then a turn and return along the pipeline to land at Smolensk-Yuzhny.
Ten minutes into the flight, one of the representatives requested a landing at the 295 km mark of the gas pipeline to inspect work. The commander decided to land on a site selected from the air, informed the MDK controller, and executed the landing. After landing, the representatives exited the helicopter and asked the commander to fly to the Lisichino area and wait for them while they walked along the pipeline. The commander took off and flew to the designated location.
Accident Occurrence
During the subsequent landing at that site, selected from the air, the helicopter's tail rotor made contact with the ground, resulting in its destruction. The helicopter then lost control, rolled over onto its right side, and caught fire. The commander shut off the engine (further details unspecified).
