What happened
During a mission to survey for forest fires, a single-engine aircraft departed from Nizhneudinsk Airport. The flight was carrying a crew of two pilots and two observers. As the aircraft reached an altitude between 150 and 170 meters during its climb, the engine began to exhibit significant vibrations.
In response to the mechanical instability, the captain initiated an emergency descent to perform a landing. The aircraft subsequently crash landed in a marshy area situated approximately 4.9 km from the departure airfield. The impact caused the plane to come to rest in an inverted position. While the aircraft sustained damage that rendered it a total loss, all four occupants managed to exit the wreckage without any injuries.
Findings
- The aircraft experienced engine vibrations during the initial climb phase.
