What happened
During a morning flight intended for forest fire monitoring, a single-engine aircraft departed from Vilyuysk Airport. Approximately one hour and twenty minutes into the mission, the aircraft experienced a total loss of engine power. In an attempt to perform an emergency landing following the failure, the crew navigated toward a wooded region where the plane impacted the ground.
Upon impact, the aircraft caught fire, resulting in the complete destruction of the airframe. The wreckage was subsequently located approximately 195 km southwest of Zhigansk. Despite the severity of the crash and the ensuing fire, there were zero fatalities among the three people on board, which included two pilots and one observer. All occupants survived the incident without injury.
Findings
Investigations into the accident determined that the engine ceased functioning during flight due to a camshaft failure.
