What happened
During a mission intended for the delivery of supplies, an aircraft was operating at a low altitude approximately 37 km north of Dibrugarh-Mohanbari Airport in Assam. While the crew was performing a supply drop, the plane suddenly became uncontrollable and descended into a crash. The impact and subsequent fire completely destroyed the aircraft.
There were eight fatalities recorded among the occupants of the aircraft during the accident.
Findings
Investigations into the accident determined that the pilot experienced a total loss of control due to an item from the cargo being released. Specifically, a sleeping bag that was part of the air drop consignment became lodged and inflated over the port tail plane, interfering with the aircraft's flight controls.
