Accident Details
Eleven minutes after departing Mohanbari-Dibrugarh Airport, the pilot reported the aircraft's position to air traffic control. Shortly thereafter, the aircraft struck a mountain and crashed near the locality of Saku. The impact destroyed the aircraft, and all six occupants on board died.
Investigation Findings
Official investigation findings attributed the accident to an error of navigation by the pilot. The pilot entered a wrong valley and, without properly assessing the performance of the fully-loaded aircraft given the available space, attempted to execute a steep maneuver. This maneuver was insufficient to recover from a stall, leading to the crash.
