What happened
Shortly after taking off from Mohanbari-Dibrugarh Airport, the pilot contacted air traffic control to provide a position update. This communication occurred approximately eleven minutes into the flight. Not long after this report, the aircraft collided with a mountain in the vicinity of Saku.
The impact caused the total destruction of the plane. There were no survivors among the six fatalities recorded during the accident.
Findings
Investigations concluded that the crash was the result of a navigational error by the pilot. The flight crew inadvertently entered an incorrect valley. While attempting to maneuver within the limited space available, the pilot attempted a steep turn that the heavily loaded aircraft could not sustain. This maneuver led to an aerodynamic stall from which the plane could not recover.
