What happened
While maintaining a cruising altitude approximately 55 miles west of Jorhat, the crew encountered technical difficulties that led to an in-flight fire. The aircraft subsequently lost control and impacted the summit of a mountain at an elevation of 2,000 meters. The crash forces and subsequent post-crash fire destroyed the airframe. Among the occupants, only one passenger survived the incident. The remaining personnel, comprising the flight crew and other passengers, did not survive.
Findings
The sequence of events indicates that technical problems initiated a fire during the cruise phase of the flight. This event rendered the aircraft uncontrollable, leading to a high-altitude impact on a mountainous terrain. The destruction of the aircraft was attributed to both the kinetic energy of the impact and the intensity of the post-crash fire.
