What happened
During an en route flight phase, the aircraft experienced a critical mechanical issue when one of its engines failed. This loss of power rendered the airframe uncontrollable, prompting the crew to initiate an emergency ejection procedure. Following their departure from the cockpit, the unmanned machine entered an uncontrolled dive and impacted the terrain. Despite the severity of the crash, all four members of the flight crew were recovered with no reported injuries.
Findings
The official investigation identified the primary factor behind the incident as a mechanical malfunction. Specifically, the loss of thrust due to the engine failure was cited as the direct cause that led to the loss of control and subsequent ground impact.
