What happened
During a local training mission originating from Chushul Airstrip, the aircraft experienced a mechanical failure involving one of its engines while in flight. Following the loss of power, the occupants of the plane attempted an emergency egress. Six individuals successfully exited the aircraft via bailout.
Despite the successful evacuation of most passengers, the aircraft continued on its trajectory and subsequently collided with a rocky mountain peak. The impact resulted in the deaths of the three crew members who had remained onboard the aircraft during the descent.
Findings
An investigation into the accident determined that the primary factor leading to the crash was an engine failure occurring while the plane was airborne.
