     The Interstate Aviation Committee Investigation team has completed the investigation of the accident with An-2Т RA-01419 aircraft owned by "Polar Airlines" JSC occurred in the area of Vilyuysk town (RF) on August 16, 2013.
     The accident with An-2Т RA-01419 aircraft was caused by emergency landing at the landing place in marsh area selected from air that resulted in main landing gear dipping in soft ground, dynamic pitch-down moment followed by engine ground impact and fuselage separation along engine mounting fitting, airframe structure and gear damage.
     Gasoline pipeline destruction during engine separation from aircraft frame and gasoline ingestion on the hot parts of power unit caused fire which almost completely destroyed the aircraft. Wrong PIC's actions who didn't turn off ignition and shut off fuel before aircraft landing could contribute to the fire.   
     The emergency landing at the landing place selected from air was caused by oil temperature increase and pressure drop below specified by the aircraft FOM values in flight. It wasn't possible to determine the cause of temperature increase and oil pressure drop due to engine component substantial damage during fire. 
     The appropriate safety recommendations based on the investigation results were developed.
