What happened
During an en route phase of flight, the operating crew reported significant technical difficulties with the airframe. Recognizing the severity of the situation, the captain made the decision to evacuate the aircraft immediately. All four members of the crew successfully bailed out before the machine lost control completely. The aircraft subsequently dove toward the terrain, impacting the ground and sustaining total destruction upon impact. Despite the catastrophic loss of the airframe, all four individuals were located alive following the crash.
Findings
The official investigation concluded that the incident was triggered by an unknown technical failure. No specific mechanical component or system malfunction could be definitively identified as the root cause based on the available evidence.
